Calibration Instructions

3
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.
