Issue Details

The specifications of my NI DAQ device show it has a built in CJC (cold junction compensation) sensor. How do I use this sensor with my temperature readings? 

Solution

The CJC is active by default and is used in the calculation for your temperature readings by default. You also have the option to change the 'CJC Source' property in both LabVIEW and NI MAX. This property has three options: 

1. Built In - This is the default option and uses the built in CJC in your device to give you temperature readings. 
2. Constant - Allows you to use a constant value from which your temperature readings will be calculated. 
3. Channel - Allows you to use a external CJC routed to a channel on your device.
