CJC Calibration:

CJC (cold junction sensor) calibration only applies to the ADAM-5018

(1). Prepare a voltage source which is accurate to the mV level.

(2). Run the zero calibration and span calibration function.

(3). Use a temperature emulation device (such as Micro-10) to send a temperature signal to the ADAM module and then compare this signal with the reading from the ADAM module. If the reading value is different from the signal, adjust the CJC value to improve it.

(4). Click the “CJC Calibration” button. See Figure 5-11.
