HP 41 CV (STO) ....2nd


Thank you Gene,

I've tried all. I pressed shift and CLX/A simultouniusly during switching on; display shows MEMORY LOST and then
0.0000 (i.e. that majar claer was done), but all the same.

Even I took out batteries out during calculator was on,
all the same, only 63 registers, no more.

Thank you all, Bauscher


Then it may be as described in a response below:

1) An HP-41CV case with the logic board of an HP-41C (only 63 memories) inside


2) A memory failure

Try "XEQ SIZE 000" and tell us what is shown when you press PRGM.

00 REG 63




Thank you Gene and thank you Luiz (boa tarde, muito obrigado para a sua carta)

Both of you seem really be experts!! I appreciate.

The HP 41 CV I am speaking of is about 15 - 20 years old. I have got it from a colleague, who retired end Dec.

The problem started, when I was using a balancing program (made by Schenck company) for balancing fans in field. The program (chip to put in in one of the four slots) is using the device GTO 063. Then the program ends, indicating in the display NO ROOM.

- Gene: when I do what you are telling (XEQ 000),the display is showing 00 REG 63

- Luiz: LCD shows a thin black frame with rounded edges.
My retired colleague is telling, that he did not have noticed this behavior. So it started suddenly.
In the moment I cannot use the calculator. I appreciate any help and would like to do some SIZE STO and PRGM sequences.



Hallo, Bauscher; Wie geht's? Vielen danke, der Portugiese ist korrekt!

Please, read this post and tell me what do you really have in hands. I am a bit confused: if you have an HP41CV halfnut type, I cannot understand what is going on.

But I will not give up. Will you follow me?

Mach's gut!

Dear Luiz, voce fala bem alemao; muito bom!! Onde voce appreendeu?

To sum up:

Thank you for not giving up.

I have 2 HP 41 CV. First is okay, second I have got from a colleague, who has retired end Dec.

Sometimes I work as a field engineer and I balance big fans in pellet plants (like CVRD, Samarco and Ferteco, near Belo Horizonte MG and Vitoria ES, you know better).

For this I am using the calculator with a module (set in in one of the 4 slots). The module is made by Schenck.

With the first calculator everything is okay, with the second calculator (the one, which I received from the colleque recently) not. The program is not running, because it stops, indicating in the display NO ROOM. At a certain step the program is telling GTO any register > 063. This is the moment, where the program stops, because the HP has only 63 free registers (from 000 to 062 i.e. sum = 63). I am not able to increase the registers. It works only up to XEQ SIZE 063. When I press XEQ SIZE 064 the display is saying TRY AGAIN. No master clean or XEQ PACK is improving the situation. That means STO (and RCL) up to 062 is working, STO and RCL 063 and larger indicates NONEXISTING in display.

Do you have any hints? A proximo!


Hallo, Bauscher;

Danke. Your Portuguese expression is also very good. Ich mag die Deutsche Kultur, but I did not have the chance to study German, I just attended six classes and felt I must learn it, it amused me. When I write something in German (like the few words above) I first write in German than I spell check it and finally I use a translator from German to English. If the translation makes sense, chances are the sentence is "korrekt, rechts?". It seems to me you have been in my country some times, am I right? My brother, Paulo Vieira, have already been working at CVRD for many years, but he was in Rio de Janeiro.

Well, let's go for the calculators: I still believe you have an HP41C (fullnut type, earlier) mainboard built inside an HP41CV case OR you have a genuine HP41CV with a failure RAM IC. In the second case, what happens is the following. (a bit of HW) The fullnut type 41CV has six RAM chips, being the first chip (1LA701) a 16-register long and it holds the system "variables", known as the stack registers (X, Y, Z, T and Last X), ALPHA registers (despite being one single memory reference, the system uses four internal registers to hold it), flags and other data. The second one (1LE701) is 64-register long and holds the first 64 registers (you see only 63 because there is a permanent .END. that always uses three bytes and kind of "hide" one register from the count) and it is present in any fullnut type, being it a C, a CV or a CX. When any of these RAM chips fail, the calculator will not switch to ON (I saw an HP41C that insisted on a MEMORY LOST because the 1LA701 had a bad soldering contact with the mainboard). The last four ones (from 1lE702 to 1LE705) hold 64 registers each and are equivalent to four Memory Modules or one Quad Module in the HP41C. If by any reason one of them is no longer working, the remaining ones will never be part of a PROGRAM, but if they exist, they can store data.

Now let's perform some tests and verify what's going on. Think of an HP41C without any data stored on it and one single memory module. Plug the module in port two instead of port one, switch the calculator to ON and execute [SIZE 000]. Toggle to PRGM mode and you see [00 .REG. 63]. If you execute [RCL] 63 you get an instantaneous [NONEXISTENT]. BUT if you execute [RCL] 64, the calculator will not complain. If you switch the calculator to OFF, remove the module from port two and plug it into port three, switch the calculator to ON and execute [STO] 64 again, you have [NONEXISTENT] back to the display. Now do the following:

input   press     display

128 [STO] [STO _ _ ]
[shift key] [STO IND _ _ ]
[.] [STO IND ST _ ]
[X] [ 128.00 ]

You'll see [STO IND X ] briefly in the display, and if everything is fine, no complains again. In the first case, the missing port-1 module leaves a gap in memory that is 64-register long (R00 to R63) and the first "existing" register is number 64, as long as you have the first ones defined as program memory (what is done by the [SIZE 000] execution). In the second case, the gap is now 128-register long (R00 to R127), being R128 the first one existing. This seems to happen because the system probably checks for memory contiguity at program (uncommitted) level, there is no need to check for memory contiguity at register level.

If you have three modules plugged each in ports two, three and four and you execute [SIZE 000 ], you will still see [00 .END. 63 ] in PRGM mode, provided no program is stored in the calculator. But you may access from R64 to R255 in this case. So, try it: execute SZE 000 and try recalling memory contents (with indirect access) from 64 up to 318, just a few of them in the range for each RAM chip (e.g.: 64, 128, 192, 256; these are the first positions for each of the four RAM chips when you execute [SIZE] 000)

Hope this helps.


I think he said the "bad" machine has the halfnut rounded display corners. It sounds like the machine most likely has a bad RAM which is located in the display module... not really fixable.


Hi, David;

I agree with you, I also had the feeling, but I thought I could even help others in the same situation. Anyway, do you know how does the actual HW "fit" in the halfnuts LCD assy? I wonder if we may find PQPF or resine bubbles, like the ones in the fullnuts' LCD divers. Do you have any knowledge about this?

If it is a halfnut, I have no knowledge about the LCD's contents or the RAM circuitry.

Just for being sure, I'm including a photo (scanned image) so Bauscher may check. (big image, will not fit in the screen...)

Hope this helps a precise identification.



Hi David, Hi Luiz, thank you very much for all the conversation and help. I am only a small user, I never needed to go in to the details so far, so please excuse me, if I need a bit more time to understand all.

First to Luiz: Eu falo Portugues so um poco, so umas palavras. Estava em Brasil 15 vezes, a primeira vez 1987, nas ultimas duas vezes ultimo ano.

Second to the calculators:

The good one has Serial No. 2907S20384.
The bad one 2541S21111.

The program for the balancing I am using is a module:

C. Schenck AG
ID 21/31 Singapore

and additionally 8619. Also is it written CAB 41 on the small side.

(Schenck is a company; which is manufacturing all kind of equipment which is required for vibration measuring and monitoring)

The program (module) works without problem in the good one.
In the bad one after some short time NO ROOM is to be seen in the display. I have put it in slot, or as you say, in port 2. Module was working perfect in good calculator for the last 15 - 20 years. I have not put any other module in the slots.

Now I am trying to do, what you are telling.

- master clear is being done. Display showed MEMORY LOST and than 0.0000.
- I inserted module HP 82181A (X MEMORY) in slot 2.
- I switched on, I executed SIZE 000.
- In PRGM mode displays shows 00.REG.63
- I executed RCL 63. Display shows NONEXISTANT.
- I executed RCL 64. Display also shows NONEXISTANT.
You said, calculator would not complain. What shall I do??

Thank you Luiz for the photos. Both calculators have round edges, i.e. they are both halfnut types (I am beginning to learn).

Thank you.


Hi, Bauscher;

Wow! You must say "I speak Portuguese", not "I speak A BIT OF Portuguese". There are some guys in Brasil that would write what you wrote with grammatical errors, and your Portuguese, for a Deutschlander (is it correct?), is perfectly understandable. Zillion times better than my poor deutschesprechen ... Now I'm ashamed of trying.

Well, for the calculators: I'm sorry I did not express myself in an understandable manner. The X-Memory (HP82181A) you plugged in your calculator will need an X-Functions module (HP82180A) for working, otherwise its memory capacity (238 extended registers) will never be accessed by the normal functions. And the functions and procedures (create data files) to access the X-Memory are way beyond the simple and handy [STO] nn and [RCL] nn. There are four options to access x-Memory's contents:

1 - Use an HP41CX, that already have the X-Functions as default
2 - use an HP41C or CV (not a CX) with an X-Functions module to access the X-Memory
3 - use another wizard module (I believe PANAME does it) that will allow the X-Memory to be accessed and
4 - the least probable, the Schenck module provides X-Functionality, I don't know if it does.

The examples I gave were based on the fact you might have an HP41C instead of an HP41CV to illustrate what might be happening. The memory I intended to use as for an example was the HP82106, a single Memory Module that should be used only in the HP41C, neither the HP41CV nor the CX should use it because of address conflict (internal 256 upper registers in the HP41CV and CX are internally mapped as having the same address as four HP82106A memory modules or one HP82170A Quad Memory module). I'm sorry I did not explain it this way.

Now, after all you mentioned, my only concerns are about the fact that your HP41CV has a failing RAM. If it is an HP41CV halfnut, the only way to transform it into an HP41C is by changing the LCD's module. And changing the LCD in a halfnut type as a complete block is not too hard, provided that the halfnuts have the same connectors found in the fullnuts to keep the LCD assembly in place, say, they have the metal small brides (smaller than the ones found in the fullnuts' LCD). And this can only be done if the calculator is opened by someone, what I believe was not done by your friend, right?

I'm almost sure the other key sequences I suggested did not work too, right? Say,

128 [RCL][shift][.] X
192 [RCL][shift][.] X
256 [RCL][shift][.] X
Did you try any of these?

The next possible step now is trying to find a Quad memory module or one single standard Memory Module, plug it in Port one, execute [SIZE] 000 and try [RCL} nn, nn>63. If the memory is bad OR it is a sheep (HP41C) in a wolf's suit (HP41CV), it may work. OR a bigger step: opening the calculator. Can you do that? Anyone you know could do that? If this calculator is mine I'd have already opened it and tried something. But the big problem is that it is a halfnut, and it's easy to mess it up if you do not know what to do. And I have not gone into the LCD's assembly of a halfnut so far...

There is another thing: what do you get when you list ([CAT] 2) the Schenck resources? Do you have a printer so you can hardcopy the resulting list? I'm curious to know if it has only programs or also functions, who knows... I have never seen one of these.

Success and forgive-me not helping the way you mostly need. I posted my e-mail address, if you want a private converstion, but I confess I like to discuss calculators at a community level, mostly because if I miss something, someone will surely call our attention for that. This IS the forum!

Mach's gut!

Luiz C. Vieira


Dear Luiz, thank you for the fast answer. ..for a German..
correctly it is ..für einen Deutschen... if it is a male person; for a female it is ..für eine Deutsche..
..Deutschlander.. does not exist, not as Highlander.

Don't be ashamed, keep on trying.

Now to the calculators:

When I do balancing I am only using the Schenck CAB 41 module, not any other module, and it works. I have a booklet from Schenck company (about 40 pages), in which the different possibilities are explained. But it is in German.
I can send it to you via fax or via normal post, if you want. When I do CAT 2 it starts like CSD-CAB41/1.....SIZE?....PSIZE....RCLFLAG.....STOFLAG....and so on. I don't know how long the program is, so I stop for the moment. I have a printer 82162A. But I have received it only recently with the second HP 41 CV. Is the printing working automatically or must I go through CAT 2 step by step with R/S on the calculator and press PRINT on the printer step by step? Anyway, if you are interested in the single steps of the Schenck program I will do. Pls. tell me.

PS: The Schenck module is working in any of the 4 ports.
I can do 1 stage up to 4 stages balancing, polar and fixed location spreading, sum up different masses to one resultant mass, everything, what is required to balance big machines outside in field.

Now again back to the bad HP 41 CV. As I received it from the collaegue, there had been 2 modules coming with the calculator. The first is the HP 82181A (X MEMORY) and the second one is the HP 5061-5256 (X FUNCTIONS); also 8931 in the plastic bottom. I have seen the both modules for the first time in Dec., as they had been coming along with the
bad HP 41 CV. I had no requirement to use it before Dec. with my good HP.

The calculator was not opened so far by anyone, that is for sure.

I have tried now with module X FUNCTIONS in port 1 and X MEMORY in port 2 thr same as you told before; i.e.
SIZE 000 then PRGM and 00.REG63 was to be seen. The I did RCL 63, showing NONEXISTENT. Again by pressing RCL 64 also NONEXISTeNT is on the display. I have stopped now, do have same advice? Beginning of January I did some balancing in a power plant. At that time also the bad one was working perfectly.

I did 128 RCL....,192 RCL...,256 RCL.... Always NONEXISTENT is coming in the display.

After I did SIZE 000 not any RCL is working. Even RCL 00 shows NONEXISTENT. Only after SIZE up to 063 I can use RCL
(and STO of course). When I press SIZE 064 display is showing TRY AGAIN.

To sum up: good HP is working only with Schenck module perfectly, bad HP is working not, either if I put the 2 modules in or not. From outside they both look same round edges and HP 41 CV written on. Good HP starts program without problem with first question (How many angles? Of course I am saying then 360°). Bad HP indicates before coming to that step NO ROOM.

We can also cummunicate with seperate own e-mail number, but
as you said, maybe the dicussion can also be helpful to others. I don't mind. E-mail adress will of course be company number of TLT.

By the way, we have good contacts to Ventiladores Bernauer in Sao Paulo, tecnologia do ar e meio ambiente.

Muito obrigo, ate logo.


Hello, Bauscher;

well, definitely your HP41CV has only 64 registers, being the last one used by the permanent .END. I cannot understand it in any other way except for a bad RAM. This is easily understandable in a fullnut type, but that's the first time I "see" it in a halfnut.

The only reasonable way out (without opening the calculator) is to use one extra Memory Module or a Quad Memory module, but you should try first to see what happens. If the program uses less than 127 registers, one single 82106A will do the job.

About the X-Functions and the X-Memory, there are many, many other resources available so you can use these features, but you should get a bit acquainted with the "philosophy" surrounding the X-functionality. If you want to we can go any further, but chances are these modules will not be of much help if you do not change the original program so it can access X-memory to store and retrieve data instead of using conventional memory. Both X-Functions and the extra X-Memory allow you to use up to 360 data registers, but you would need to create a data file and use SAVEX and GETX (instead of [STO] nn and [RCL] nn) to "sequentially" access stored data. And it is more likely that the Schenck programs do not provide this functionality.

Well, my friend, I did not give up yet, but I have no other reasonable suggestion that trying to see if an extra 82106A Memory Module (better if it's a Quad Module) is enough for your program to run. I have one 82106A with me and I'd gladly send you the module so you can test to see if it is enough for what you need, but I believe you'll find this type of module closer to where you are. Please, let me know if you need it or not. If you test and it works, you will be sure your HP41CV behaves as an HP41C (perhaps Doc. Mike, as a psychiatrist, would accept the case... Kidding, Doc, kidding...) and the memory module can be used.

Sorry, I'd like to see a better closing for this case.

Mach's Gut.

Luiz C. Vieira


Thank you Luiz,

do you think, that another module will help? I am not quite sure now. Just keep in mind:

- good HP is working with Schenck module and without any other module.

- bad HP not, even with one X MEMORY and one X FUNCTIONS module.

Can it be, that it is not a memory fault? Both calculators accept STO and RCL 63 and answer to RCL 64 NONEXISTENT.

Thank you very much for offer, I think that another module will not help.

What is a Quad module?

Thank you,


Hallo, Bauscher;

I read your posts again and I failled in a very important point: you mentioned in previous post that NO ROOM message appears when running the Schenck program in one of the calculators (how could I miss it???). Well, NO ROOM message only appears when you try to access extended memory and there is no room to store data, say, when you try to access more extended memory than you have.

I believe you need both X-Functions and X-Memory to run the Schenck program in any HP41CV (or simply the X-Memory in an HP41CX) because the only way to generate NO ROOM message (unless it's written by the program itself) is by trying to access unavailable X-memory. Please, plug the X-Functions and the X-Memory in each calculator (if you have a pair of each, even better) plus the Schenck module, and do the following:

 1 - execute a MEMORY LOST with [ON] [<-];
2 - press [XEQ][ALPHA] SIZE [ALPHA] 200 (or any number grater than 64)
Was it successfull in both of them? I mean, did any of the calculators not accept the SIZE definition you choose? If both accept, chances are they will run your program alright.

Please, let us know if anything changed.

Best regards.


Dear Luiz, thank you for your mail 1 FEB 2003, 4:23 p.m.
Pls. see my mail 1 Feb 2003, 3.01 p.m.

I have only 1 X MEMORY and 1 X FUNCTIONS. Even if I had a pair, I cannot plug a pair AND the Schenck, because there are only 4 ports.

Pls. see my above mentioned mail. Good HP runs ONLY with Schenck module, not any other module required. Bad HP runs NOT, even with or without X MEMORY AND X FUNCTIONS.
I have not tried good HP with modules. I do not want to take any risk with the working one.

With X MEMORY and X FUNCTIONS plugged in bad HP, SIZE 063 is the maximum I can achieve (than RCL 00 - 62 is possible).
When I am trying SIZE 064 display shows TRY AGAIN.

I can not do SIZE 200. This will lead to TRY AGAIN.

I will not play around with the working one. I only looked at the RCL. RCL 62 possible, RCL 063 show NONEXISTENT. That means, that all both behave same, only that bad HP is showing NO ROOM.

I am sitting here in second floor, maybe when I open the window and......

Thanks again. Regards

I have tried what yiu said (Create MEMORY LOST and XEQ ALPHA SIZE 200 ALPHA) witout modules with the 2 and with the 3.

All the same TRY AGAIN. only difference, that together with the SCHENCK the HP switches automatically to USER mode. In this I can of course not do XEQ.....


Hallo, Bauscher;

Well, I'd like not to be so far, because I'd be waiting for a flying HP41 hight below your window... ;-)

Anyway, I was reading your posts again and it seems that the Schenck module alradey has the extended functions set built on it. In Jan. 31, 12:39PM you wrote:

"When I do CAT 2 it starts like CSD-CAB41/1.....SIZE?....PSIZE....RCLFLAG.....STOFLAG....and so on.

I'd like to have a look at the user's "handbuch", at least the specifications for this module and the memory requested to make the programs run. I have in mind that it is a complete X-Functions with an extra program listing. In this case, you could try a single procedure for now:

- take the bad HP41 and keep yourself as far as possible from the window or keep it closed... :-)
- connect the Schenck module on it
- proceed with a [MEMORY LOST ] wit [ON] and [<-}
- press [XEQ] [ALPHA] SIZE [ALPHA] 063
- execute the progra
You mentioned a couple of things I'd like to understand, but I believe if I have a look at the module's "handbuck" I'm gonna find the answers. For now I'd like to know:

• What are the starting procedures for using the Module's resources?
• Does the calculator go into USER module at the moment you plug the module in and turn it to ON?
• Have you noticed if the calcualtor automatically start running a program?
• Do you have to [XEQ] anything before using the module's resources?

There is an Autostart and Duplication module for the HP41, so there is a way to force the calculator to run an specific program at the moment it is switched to ON. Also, as the program is running, the X-Functions allow an on-line keyboard scanning, so the program does not need to stop for data input, if this is the case.

Two notes by my own:

• When I mentioned the posibillity of having a pair of each X-Functions and X-Memory modules, I meant one of each in each calculator, not all four in one. The ROM modules must never be used with "replicas" in the same calculator because of logical conflict. They have resources with the same logical address and there would be problems if both resources are availble in two different addresses. In other hand, you can plug two X-Memory modules in one HP41CX or an HP41C/CV with an X-Functions, provided they are both in one even- and another odd-numbered port at the same time, say, they must never be in the same "column", related to the ports position.
• The USER mode may be canceled by pressing [USER] key again; I do not know if it is possible with unconventional resources, but if you cannot withc off the USER mode wihile the calculator is using the Schenck module, so we have not only a rare module (in fact, it is the sort of module that may only be usefull for the realted Schenck equipment) but a module with resources to fully customize the HP41.

Well, Bauscher, if it is not asking too much, is it possible to scan the module's manual and let me have a lok at it? Maybe most of the answers for these questions are already there.

Once again, I wrote too much. I'd like to invite others to participate and post in here, there is something I'm probably missing.

Mach's gut!

Luiz C. Vieira


Dear Luiz, thank you for answering. First i have closed the window. It is anyway better, because we have winter time here.

To work with the SCHENCK-program is very easy. You plug the module in and switch the calculator on. The calculator goes automatically in USER mode. Then the calculator is waiting for the further steps. The program does not start automatically. The module can do lots of different programs (maybe 10). Automatically the keys will be assigned to special devices, they will not initiate the old meaning.
(For example: the key square root will lead to german dialog, the key LOG will lead to english dialog, the key LN will lead to french dialog and so on.). Together with the module it was coming a mask, which I can lay over all the keys, so that I can see what will happen, when I press them.

Tomorrow I am trying to scan you some pages of the manual and of this mask, but you will not find much information about the internal module design. 95 % of context is what programs are in, and how to start.

Further it goes. Module in, calculator started, I pressed Square root (for german language), X><y (for single plain balancing). That's all. Then the program begins to ask me first question. I put in the answer and the calculator is continuing after I pressed R/S. Then second question and so on, until the results are there.

To aour questions:
- What are the starting.... Only switch on and press the key for the program you want to execute.

- Does the....USER... Yes.

- Have you..... No, it will not start by its own. I must press a certain key (acc. to the program I want to do).

- Do you .....No. no XEQ required. When I press XEQ the calculator does things which are according to the newly assigned key (in this case POLAR cordinates of the result).

After switching off USER modus, I can calculate normally, even with Schenck module still in the calculator. All keys are assigned to what they shoud be. Some flags are still set, but I put them back by pressing CF 00 and CF 02.
(Other flags are also changed, e.g. the dot in decimal digits, american and german writing as 1.234,4 or 1,234.4
some flags 27 28 29 or so, I have to look up, but that is not important here.)

I tried to print out what is behind the Schenck module. The following happened: When the printer was connected, after pressing CAT 2 only all normal HP devices in alphameric order were shown. The contens is only shown with printer off. I must stop each step by pressing R/S.

Schenck is running in good HP without other modules.

Now I have tried what you have said (window still closed!!)
1. Schenck plugged in.
3. XEQ SIZE 063 Answer: TRY AGAIN !!!
(Pls. notice, that before step 3 I had to go out of the USER modus, otherwise the program started some calculation acc. to the assigned key).

Very sorry, program not running (still window closed).

I would like, if others could join, maybe there is some engineer, who also is using this CAB 41 (Schenck's name for the module.)

Thanks, Regards


Dear Luiz, sorry, one mistake, third paragraph from the end:
Now I have tried ........In USER modus it is showing NONEXISTANT, when I press XEQ, program of course is not running.

Now I will open the window (maybe).

Regards Bauscher



this is the biggest interrogation point that foolows me everywhere I go (If I'm Felix, the cat, I've already found something to do with it...). How come? If the module has a sort of engine able to activate USER mode at the moment you switch the calcualtor ON, what other settings does it alter? That's what I want to find answers about in the module's "handbuch" (I wrote this wrod the wrong way in my previous post... Entschuldigen Sie, bitte! It's too polyte, rechts?)

The other doubt goes for the SIZE requst denying. Assignmets for global labels are stored in the labels themselves, but function assignments are stored in convetional memory ("uncommitted registers" in the newer HP41 literature). So, if the Schenck module also assigns functions to keys, some registers will not be available. Would you, please, try (sorry if I am using this sort of "what...if" technique) a sequence of SIZE nnn starting with 062 and lower the nnn value (061, 060, 059) till you find the one that fits in actual available memory? Maybe you'll find a reasonable amount of memory that the program will accept.

Another thing: as the module is inserted (only the Schenck module) and the calculator in ON, would you please try a simple command?

set USER mode mode OFF
then you tell me what happens and if there are no error messages, tell me what value remains in teh X-Regiater.

The last hint is to contact Schenck's support and ask for possible problems.

Sorry, I'd like very much to "see" it working.

Mach's gut!

Luiz Claudio Vieira


Dear Luiz,

of course I apologize, but the english right is coming from allright, that means: everything ok? Right is correctly translated into the german 'rechts', but that means the opposite of left. rechts = direito (nao esquerda). You could not use it the way you used it.

I have witnessed the following alterations after the balancing program is finished: flag no 00 set. flag no 02 set. digits after the dot: 2 (as shift fix 2). flag 28 cleared (answer to shift FS? 28 will be NO). flag 29 set (answer to shift FS? 29 will be YES). This lead to the display: 999999999.11 instead od 999.999.999,11 (as we Germans write).

If I take the good HP only from 064 and greater the display show TRY AGAIN (shortly PACKING appears). If I take the bad HP TRY AGAIN is coming with 063. (good HP is accepting SIZE 000 - 064 without complaining, bad HP only 000 - 063.)
Status: good HP: USER off, Schenck plugged in, bad HP: USER off, X MEMORY and X FUNCTIONS plugged in.

When I do XEQ ALPHA EMDIR ALPHA the result is (display):
good HP: NONEXISTANT; bad HP: DIR EMPTY. Status as above.
What is the X-Register?

I think, that Schenck will bring no help. The equipment is 15 - 20 years old. Noone will remember. Because they are pretty large (we buy lot of equipment from them), they will say: Why don't you buy a CD for your notebook with advanced program and more possibilities?

Ate logo, vamos tomar caipirinha!

you started a new thread in here, but I posted an answer in your first thread; I just want to know if you read it.

Anything new?
