Hello,
I have a problem reading thermocouples and 0-10 V voltage signals simultaneously with an Agilent 34970A in LabView.
I used the Agilent components from the "HP34970A Advanced Scan" example. The VI and a screenshot are attached.
If I read out the thermocouples only, the VI works. Reading out the voltages alone also works. I can also read out resistance sensors without any problems.
The problem occurs as soon as I want to read thermocouples and voltage signals simultaneously (in one scan). The Agilent then gives an error tone. (Thermocouples and resistance sensors at the same time or voltage signals and resistance sensors at the same time are also no problem.)
I suppose the reason for this is that the thermocouples are in principle also a voltage measurement. If I use the BenchLink software, everything works simultaneously without any problems - so it is possible in terms of hardware. Is there a way to use the Agilent components in LabView so that thermocouples and voltage signals can be scanned simultaneously?
Best regards,
Michael
