Cold Junction Compensation, Open-Circuit Detection and Digital Filter.
5.5.1
Cold Junction Compensation
Cold junction compensation only specific to thermocouple, other input type is invalid.
Cold junction and hot junction
Measuring terminal of thermocouple is hot junction, the terminal that is connected to measuring
circuit by leading wire (input terminal) is cold junction.
About thermocouple cold junction temperature compensation:
In theory, thermocouple cold junction use 0°C as standard to begin measurement, but when
make measurement, instrument is usually under condition of indoor temperature, because test
input terminal (cold junction) is not 0°C, it leads to thermos potential difference decrease,
which will make measurement incorrect and cause error. In order to minimize error, the
indemnifying measure is cold junction temperature compensation.
Instrument built-in cold junction temperature compensation function, users can turn it on or off
by [Compensation] field.

to thermocouple/RTD/Resistance whether thermocouple is bad contact, whether thermocouple
is broken or not, numeric display field appear OPEN.
