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.
