Hey everybody,
I'm currently tryinng to set up resistance measurements with a Keysight DAQ970A using LabVIEW 2020 on Windows 10. The trial resistance is connected to channels 105 & 115 by 4-wire connection. The DAQ970A is connected to my PC via USB. Attached you find my VI for reading the resistances. I use the sVIs from Keysight specifically for the DAQ970A.
There are two major issues appearing:
First, LabVIEW seems to read values of 1.00, no matter if the channels is occupied. I also had runs, where occupied channels read 1.00 and empty channels read 9.00, but I can't reproduce that at the moment. Nonetheless, I never got the exact measurements of around 109 Ohm, that DAQ970 shows for the occupied channel on its monitor.
As my measurements didn't seem to work out using the VIs from the DAQ970A-palette, I tried setting up my LabVIEW code using the Agilent 34970-palette's VIs. This leads to my second issue: Using the VIs from the 34970A-palette gave me error code -252 "Missing media" but at least showed the correct measurements. Nevertheless I was concerned about the error and tried to work with the frist VI (using the DAQ970A-palette) again but now the error persisted. I did not find any information on how to fix this error.
Can anybody tell me how to get a resistance measurement running using the DAQ970A-palette and how to solve error -252? I would be very grateful!
As a background information - I have the following driver and suites installed on my machine:
- IVI Shared Components 300
- DAQ970A Data Acquisition System IVI-C Driver 1.0.0.0 64-Bit
- DAQ790A LabVIEW Driver 1.0.1.0
- IO Libraries Suite 2022 Update 1
- Keysight Instrument Control Bundle 6.2020
