Cold Junction Compensation
Calibration
To recalibrate or check the cold
114
junction measurement system for both
input and output, use an electronic
thermometer with a maximum error of
±0.07°C (0.13°F). Remove the
compensation wire fixation screws
from the T/C terminals. Insert the
thermometer probe in the appropriate
T/C terminal hole and make sure a
good thermal contact is made down at
the bottom of the terminal. Take
measurements samples of both
terminals and calculate the average
temperature. Enter this temperature
to recalibrate. Do not use thermal
conductivity gel as this can not easily
be removed from the terminal.
