Power up
In this menu there is a button for each slot for Cold Junction Calibration. Calibration is per-
formed per slot/card.
• Select the desired slot button. If a CJC connector is not fitted a message box will
appear.
• The CJC temperature reading is displayed in the CJ Temp column.
• If the known temperature is different to the recorder’s reading an Offset can be entered
to make an adjustment to future values. The Cold Junction temperature should be
measured at the point where the thermocouple is connected in the terminal block.
Ensure the measured temperature is accurate to within 0.1
°
C.
• Enter the difference between the CJ Temp on the recorder and the measured reading
as the Offset Value. The offset is added to all future readings and displayed in the Cal-
ibrated CJ Temp column.
• The Measured Temp column will display the actual temperature using the Calibrated
CJC Temp, on channels with T/C fitted. For more details of how a thermocouple works,
refer to
“Appendix C: Thermocouple Connections” on page 247.
• Select the tick box to go back and the Finish button to Commit, Discard or Commit
Later.
