Thermocouple Sensor Type
Background
The DM2571 accepts thermocouple inputs and calculates
the temperature from the voltage difference of two
dissimilar metals. Thermocouple sensor type is one of
the main factors to be considered.

Reference Junction Temperature (SIM Temperature)
Background
(Thermocouple
only)
When a thermocouple is connected to the DM2571, the
temperature difference between the thermocouple lead
and the DM2571 input terminal should be taken into
account and be cancelled out; otherwise an erroneous
temperature might be added. The value of the reference
junction temperature should be determined by the user.
