For Cold Junction compensation, you will also require a stable
temperature source, for example an ice bath, and a conversion table
to provide the sensor’s corresponding
µ
V value for the bath’s
temperature.
Note…
Before calibrating/adjusting the inputs, the ASM-80x must
have been turned on for at least half an hour.
In order to calibrate the inputs the following calibrated signals must be
used:
Nominal values
