Answer Posted / anzal
IF U USE MV INJECTOR FOR THERMOCOUPLE CALIBRATION.........
FIRST U SHOULD MEASURE THE ROOM TEMPERATURE AND TO COMPUTE EQUELENT THERMOCOUPLE VOLTAGE.......V REF....
IF U R INJECTING 100 DEG EQULENT MV U SHOUD DEDECT V REF MV FROM THAT ACTUL MV...AND APPLY ADJUST 100.......
IF U R USING TEMPERATURE CALIBRATOR NO NEED THIS ONE ...U CAN APPLY DIRECT......BECAUSE IT GIVES THE COMBENSATED OUTPUT
