34970A termocouple configure

So, i remove de sequence structure and kept the changes, but it still re-changing for j-type, indifferent of my choice.

And what does the trace file show?

You're leaving the transducer type unconnected so it default to  "last", you should try to set it to 0 (thermocouple). In your picture the thermocouple type seemms to be set to 8: Def-T, that strange the driver i'm using the value of 8 is Def-Last (notT). That could be the reason but it's hard to tell by seeing just a part of the block diagram.

So, this is my VI in LabVIEW 8.6

[Kossmann]

I dont know how to use trace file 😕

[Dennis_Knutson]

It's in MAX. Older versions were called NI-Spy. You open it and turn capture on.

NI Trace show me it

You'll have to look at the complete string for the MEAS:TEMP? command to see the scan list and the thermocouple configuration.

[ben64 · Accepted solution]

From what we can see you are using the default parameters MEAS:TEMP? DEF,DEF ....

Set the transducer type input to Thermocouple and the Thermocouple type to T

see the attached screenshot for an example.

I think Ben is correct. What is shown in the trace is truncated since the scan list is missing but the DEF is a problem.
