4Calibration Instructions
If a Thermocouple Calibrator/Simulator is used, such as the OMEGA Model CL511 Precision Calibrator, select the Temperature Input Z (zero) and S (span) values.
3.Set the DC mV source to the selected Z (zero) mV value. Adjust the Z potentiometer to read 4.000 mA on the monitoring instrument.
4.Set the DC mV source to the selected S (span) mV value. Adjust the S potentiometer to read 20.000 mA on the monitoring instrument.
5.Repeat steps 3 and 4, as required, until the readings are exactly
4.000 mA and 20.000 mA. This procedure is necessary since there is interaction between the two potentiometers.
