I have an HP 3468B digital voltmeter and am trying to do some remote measurement logging with it using my HP 41. The problem is that when I do an IND to get the meter data I get a Transmit Error. However, other Meter command functions work fine, includng the INSTAT command during which the 3468B transmits a data byte back to the 41. So I think the IL loop is OK? But, because the only manual I have is a partial one for a 3468A, I'm thinking I might not have a setting just right. Maybe the DVM is sending back some other form of data? Also, what is the difference between the A and B models?
Thanks
