Have you looked into the subVI to see where it is hanging up? I use RS connector with baud rate Even then its not that accurate. Message 2 of 7. Thank you very much for your brilliant inspiration. Message 2 of 8. My collegue solved my problem.

The problem with this approach is that it will turn the source off every iteration which is undesirable. Message 3 of 4.

Instrument Control (GPIB, Serial, VISA, IVI)

You don’t use the same GPIB address for both devices? Can I use similar code as for Keithley ? How do you “find” the Pickering card? The address of the controller should never be changed to match an instrument’s. If that change doesn’t work, attach the code and I’ll have keithly look. It is not the same thing as LF.

Message 1 of 7. Message 6 of How do you communicate with it?

Keithley ke199 Meter

I have a linear stair sweep program that works well so I decided to base it off lzbview that. Simultaneous isn’t possible, but in succession is i. Message 3 of 7. Message 2 of I’ve read manual for my instrument and commands arre very simple.

Message 4 of 4. I don’t see it in Your manufacturer list.

Message 3 of My collegue solved my problem. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Could that be causing the issue?

Keithley Set constant source, make measurements over lzbview of time.

Post some code and we can help you figure it out, otherwise it is just a guessing game. This would be specified in the instrument’s manual.

Message 3 of Message 1 of 4. My experience with DMMs is that there is a manual switch to tell which terminals to read.


I still not understand, would you tell me precise about this. Message 1 of You want to measure DCV on one channel repeatedly while also measuring temperature?

Keithley ke Meter – IEEE (GPIB) Driver for LabVIEW – National Instruments

Message 2 of 8. When the VI works on one computer and doesn’t on another there must be a difference. I already conduct test with temperature measure in first time, than measure DCV in next day.

You should not use the low level GPIB functions. Message 1 of
