I'm trying to read some thermocouples from an AG34980A with 34921T using Labview. I'm using the "AG34980A Configure Thermocouple.vi" to configure the channels to read Type-T thermocouples with the "internal" reference junction. But when I read them using the "AG34980A Measure Thermocouple.vi" it changes the reference junction back to "Fixed" and gives me wrong results.
I opened the "AG34980A Measure Thermocouple.vi" and it is sending this command: MEAS:TEMP? TC,T,DEF,(@1001:1040,2001:2020). In the past I used exactly this VIs to measure thermocouples using AG34980A and it always worked, why isn't it working now?
PS: this VI's came from the Labview Drivers supplied from Keysight for this instrument.
Any help or insight is welcome here, I'm struggling for a couple of weeks already...
