Calibrating a TC temperature transmitter

The following procedures will be used to calibrate and test temperature to mA
transmitter.
EXAMPLE: Transmitter has a TC type K input; 2-wire 4/20 mA output on 0 to 600°C
Switch the calibrator ON
Connect the instruments as in figure (the calibrator will supply the transmitter).
Set the CH2 in output mode and configure it for TC type K with internal Rj
compensation.
