General Information
This document will walk a technician through the steps necessary to calibrate/recalibrate the Steam QM-3. It is estimated
this process will take between two to four hours. Once recalibration has begun, all components must be recalibrated before
returning the unit to service.
Recalibration is required annually or whenever any component is changed.
What to expect:
Temperature sensors:
There are three temperature sensors which can be calibrated either by simulated measurement method or true
measurement method.
 •Simulatedmeasurementmethod—simulatestheresistancethatshouldbecreatedbythetemperaturesensor.
 •Truemeasurementmethod—placethetemperaturesensorsintheoilbathandrecreatetheactualtemperaturesfor
calibration. This method is not covered in this document.
Pressure transmitter:
The pressure sensor is calibrated by simulating the voltage created at a specific pressure.
Heating Element:
It is important to calibrate the natural resistance of the heating element and cable with the Steam QM-3 computer. This is done
by measuring the actual resistance.
Condensate Flow Meter:
Measure the average amount of condensate discharged per cycle of the EV2 valve.
Gas Flow Meter (NCG flow meter):
Measure the average amount of non-condensable gasses (NCGs) discharged per cycle of the EV1 valve.

14. Write 80 °C on the adjusted column of the calibration certificate.
15. Restart the procedure from point 5 with 140 °C instead of 80 °C.
16. Control the calibration with random temperature between 80 °C and 140 °C (restart the procedure from point 5) and
write it on the calibration certificate.
17. If the three calibrations are correct, check the valid mark on the calibration.
