I waited 25 years for this? - Casey Drew - 09-19-2011

My order for the HP15C LE came in and I immediately fired the calculator up. After my first computation, I ran the self test for the heck of it. Display comes back immediately reading "ERROR 9"

Not happy.

That's normal! It is the firmware of the original being emulated, and it's normal that the self test doesn't work because it is designed for the original hardware.

There is a different self test, I don't know from the top of my head how it works but I'm sure someone here will post it soon :)


15C LE test Re: I waited 25 years for this? - troy - 09-19-2011

1. turn off calculator
2. press g+ENTER together, do not release.
3. press ON then release.
4. release g+ENTER.

There are three 15C LE self tests, all different from those that apply to the original 15C; the manual revision process failed to reflect this.

An authoritative HP person says this about the LE tests, quote:

This also applies here to the 15.

BTW, the original keyboard self-test still works as long as you are *FAST*. The calculator speedup causes a time-out otherwise.

Whew! Great to hear!

If I am very "fast" on ON-X, I get 2.00. What does that mean?

Always get error 9 on ON-+.


Re: I waited 25 years for this? - M. Joury - 09-19-2011

Haven't a clue <g>. The only one that appears to make sense at all is "ON /" (keyboard test).

You can review postings to this list since September 9 (when gamma testers first got their 15C-LE) to see all the issues thus far identified. I identified this failure of the original self tests within five minutes of receiving mine that date.

More serious, however, is the other problem that I identified that date with the original self tests: Performing the ON plus * or the ON plus + self tests will corrupt program memory!

While we're at it, my other and most serious discovery on September 10 was the display irregularities that occur after two or more PSE commands are executed in a program's runstream.

The HP 15C-LE's new self tests are the same as those for the HP-12C+. Start them by turning the calculator OFF, push and hold g and ENTER keys, push ON, then release all keys.

Enjoy.

Real Self Test for 15C LE linked here

No idea why this procedure was left out of the printed manual that came with the 15C LE. As others have noted it is the same as the new 12C's in fact the link actually indicates 12C.

I printed a copy and included it with the 15C LE's print manual.

The manual was printed in China. That's why.

Ahh, SNAFU!


Re: I waited 25 years for this? - Howard Owen - 09-20-2011

The problem isn't with the printing, but the editing.


Re: I waited 25 years for this? - Michael de Estrada - 09-20-2011

It is when the Chinese printer ignores the US editor.


Re: I waited 25 years for this? - Walter B - 09-20-2011

Taking into account the Chinese talent in copying, I bet they printed exactly what was given to them. Textbook example for GIGO I guess.


Re: I waited 25 years for this? - Mike Morrow - 09-20-2011

All this is putting emphasis on the wrong things. Even IF the manual had been printed as desired, which was to have NO reference to any type of self test at all:

(1) That leaves in existence a couple of keyboard actions that can corrupt program memory that should NOT corrupt anything (ON plus * and ON plus +). A properly edited manual would NOT cause those problems to go away!

(2) The real self tests would NOT be described in the manual. That is certainly a deficiency.

(3) An unnecessary deficiency and difference between the HP 12C+ and the HP 15C-LE exists. The HP 12C+ apparently tolerates performance of BOTH the old self tests AND the new self tests without any problems arising. One wonders why that doesn't also apply to its doppelgaenger, the 15C-LE.

You nailed it - the manual is the symptom, the real issue is what you describe.
