COLD JUNCTION COMPENSATION
Choose cold junction compensation by the cold junction temperature sensor included in the product package for thermocouple
input.
When the setting is disabled, the terminal temperature is assumed to show 0°C so that the measured emf is directly converted
into temperature.
