I wrote a program to that uses the Keithley DMM to check voltages on multiple channels, wait a period of time, and then check again. This cycle continues for the time specified. I made this program on one laptop and it worked fine. When I moved it over to a different laptop and a different Keithley DMM, then I started to see this issue.
After stepping thru the program, It seems that the error comes from the "Configure Scan.vi". The exact error message is:
<ERR> ke2000 Error Query;
instrument reports:
-260,"Expression error"
and the error code is: -1074001424.
I searched for these myself and couldnt find anything helpful. i changed a few things around and it seems that the "scan mode" parameter seems to be the problem. It needs to be set to "internal" to read the channels on the additional scan card, but the program will return an error if it is not set to "none"... and when its set to "none" nothing happens.
Please help me out! Thanks
