Ambient Temperature Calibration
Ambient Temperature sensing is needed for Software compensation of Pressure Sensor. Accuracy of ambient
temperature (offset) is not critical for such purpose. Nevertheless, it is strongly recommended to perform Ambient
Temperature Calibration. 1-Point Temperature calibration method is implemented for this parameter. See Ambient
Temperature Calibration flowchart below.

Pressure Calibration
Three points of calibration are used for AdEM®-PTZ pressure calibration. It is recommended that prior to calibration
first remove AdEM®-PTZ from service and leave in service shop for at least 24 hours to acclimatize the unit.
Calibration should be performed at room temperature. Setup the calibration equipment (pressure controller,
hosepipes etc.). In order to perform calibration, the Program Switch on the Main Board must be moved to the
“Enable” position (refer to section 4, SECURITY). Connect the pressure supply to the unit. Check for any leakage. If
confirmed OK, set the pressure controller to the LOW pressure point (approximately 20% of the range).
