6. Enter the LM94022’s mean temperature (see red box in the figure above) in the
“T_board” field located on the upper left hand side of the GUI. The software will use
this “T_board” value to calculate for the thermocouple’s absolute temperature (Thot).
If the LM94022 or any other temperature sensor is not connected to do cold junction
compensation, then the user can still manually enter a Tcold value in the “T_board” field
box.

7. In the Sensor Window, click on CH1 to read the thermocouple’s voltage and temperature.

8. In the “Measurement” tab, choose the “Output Format” as “Output Voltage (V)”,
and click “Run” to capture the thermocouple relative voltage.
