BNC 2120 thermocouple CJC with M6289

Go to solution

I am trying use my CJC of BNC-2120 thermocouple Ic sensor for temperature measurement,but I am not able to acquire it with M6289 mass terminator device.

Whenever I make labview program using DAQ assistant,using ai1 as physical channel and ai0 as temp ref for CJC(default in device),It is giving daq error that task is not specified.

I don't know what is the program whether 6289 can control temperature sensor directly or not.

Please assist me in this regard.

You need to configure the Build in CJC channel first and then select "Build In" at the DAQ Assistants configuration.

This is explained in this KB.

Hi christian,


This option of changing properties is not coming for M6289 mass terminator device,so I can't change its properties to enable the CJC reference..

you have to be more specific with your explanations in order that we can help you!

I have absolutely no idea about what you mean with "this changing properties".


Another thing I want to be sure about is that we are talking about the same hardware. With "M6289 mass terminator" you are talking about a PCI/PXI/USB-6289 DAQ card, right?

Hey Christian,


These are specifications for my equipment: NI 6289 USB High-Accuracy (Up to 625 kS/s, 32 Ch, 18-Bit)> Link for device which I am using.


I have attached the JPEG picture of the device when I open my Measurement and Automation Explorer,You can have a look at it when I right click on my device,what options are coming out.

The image shows that the device is not present anymore since shows up in MAX in white with a red cross. It should be green if it is installed correctly and connected to the system.

By the way I got the way how to change settings.


Please check it once in the attachement if I got the right window or not.
