Cannot read resistance measurement from DAQ973A into LabVIEW. Using DAQM901A multiplexer

[chaoticllama]

Hi all,

I am new to LabVIEW and am trying to read resistance, current, temperature, and voltage measurements from a DAQ973A DMM. I am using the mutliplexer module DAQM901A and communicating with the instrument via GPIB using the Keysight drivers associated with the DMM.

The example files that came in the Keysight DAQ970 Series driver have almost got me there, but there do not seem to be options to read these parameters into LabVIEW. I can configure the DMM to measure the parameters I want and display them on the DMM interface, but cannot get the DMM to communicate the measurements back to LabVIEW. I am only seeing options to do this for Frequency, Period, Threshold Noise, and Threshold Distortion.

Currently I am trying to accomplish the feat of measuring a resistance first. The file I am working with is attached. I have also attached a picture of the Read Measurement VI not giving the option to select resistance, voltage, current, or temperature.

I appreciate any help! Thanks!

hi 

I never used this instrument. But from other instruments, you need to find the correct order to send commands and then read the data back. 

Check for samples on the provided drivers and see if there is anything on the documentation on the sequence of commands you need to send in order to read the measurement you need. 

Sorry I couldn't do more.

The Keysight DAQ97x series uses an IVI driver. Personally I have never had good luck with any IVI type driver. 

Lucky the DAQ97x series is backwards compatible with the HP/Agilent/Keysight 3497xA series drivers.

Yep, the Agilent 39470 drivers worked like a charm. Now I can do all I need. Thanks a lot!
