Note: During the direct calibration of an instrument with reference-junction
temperature compensation, it is recommended to press the RJ-ON button
so that the instrument can start the function of automatic reference-
junction compensation. Thus providing the required thermo-electromotive
forceforoutputfollowedbydisplayingthesymbol"RJ-ON"where:
Output thermoelectric force = corresponding emf of set
temperature – emf of room temperature
•
It takes two seconds for the instrument to start its internal referencejunction
temperature. After this, each automatic compensation occurs at
10 second intervals.
