Figure 5-3(b) Cold Junction Calibration
NOTE:
1. Because the CJC sensor of ADAM-4118 is located in the side
of channel 0 to 4, the measurement will have the difference ± 1
o
C between channel 0 ~ 4 and channel 5 ~ 7. The following
table is ADAM-4118 Input Range Accuracy for Thermocouple.
2. It had better send back to Advantech Repair Service (RMA) to
conduct calibration if user find or doubt the standard shift.
3. If user want to conduct calibration by themselves, please use the
high precision instruments to be a calibrating source and follow
up process the “Zero”, “Span” and “CJC” calibration in
sequence.
