Calibrate
The calibration can be done here just like on the end device. A two-point calibration with
comparison measurement device can be performed.
Procedure
1. Evacuation of the system with
search
lower point (Pmin) for the lower point.
2. Take over the value with
OK
, if the pressure is constant.
3. Ventilate the system with
search
upper point (Pmax)
for the upper point.
4. Take over the value with
OK
, if the pressure is constant.
5. Takeover the settings with
save
. The calculated calibration coefficients are displayed.
Calibration with atmospheric pressure:
Calibration with low pressure
(ultimate pressure):
The diaphragm pump is switched off
The diaphragm pump is switched on
The ventilation valve is open
The ventilation valve is closing
The vacuum control valve is closed
The vacuum control valve is opening
Sensor exposed to the ambient pressure
Sensor exposed to the ultimate pressure
With
