Trying to read temperature - Keysight DAQ970A

Hi there,

I'm trying to reading a thermocouple on a Keysight DAQ970A. I've managed to get the instrument drivers connected and dont have probelms intializing/closing and even configuring a thermocouple channel. As soon as I add a measure VI from DAQ970A library it seems to throw this BFFA4214 error.

Has anyone else had any luck doing simple temperature or voltage readings with Labview/DAQ970A with usb connection?


Thanks!

Maybe this?

 

Does the error happen immediately (on first read) or after a while? Error suggests the read times out.

Have you tried highlighting execution?

I opened the measure VI and highlighted that block, that one referenced another 970a block which I highlighted. I'm not 100% sure what the issue is at this point?

I'm just trying out DAQs atm for some suitable applications so its not the end of the world but this DAQ seems to be a bit of a pain to work with labview just to do some slow temperature measurement logging.

Theas instruments are the next gen of the venerable Hp/Agilent/Keysight 34971A DAQ/Switch unit.

 

But in general you do this:

  1. Configure measurements (voltages, current, thermocouples, etc) 
  2. Build a "scan list"
  3. "Scan" the instrument (take readings)
  4. Save and display measurements
  5. Wait for some time duration
  6. Goto 3 (Scan) or exit 

 

BTW: Here is an example of how to properly configure and use this device Don't let the fact that this example is for a 34790A, the DAQ97x are fully compatible with the 3497xA LabVIEW "drivers".

 

Our new ATE systems are using a DAQ970 now and I did not have to change a single bit of LabVIEW code!

Hello, 

i'm going to Replace 34970 by DAQ970A , do i will change any of my old code on labview as i used 34970 Drivers to acquire the temperature, voltage and current from the agilent 34970. when i connect the new DAQ970 it will be plug and play or i will use a new drivers ??

 

Thank u in advance

In general the DAQ97x series is backwards compatible with the 3497xA series. 

 

There is even a setting to make it respond to *IDN? queries as a 34970A if your software checks the instrument ID.

 

As I said above:
