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. Evacuate the system for the lower point using the
search
lower point (Pmin) (1).
2. Take over the value with
Ok
(2) when the pressure stops dropping.
3. Ventilate the system for the upper point using the
search
upper point (Pmax) (3).
4. Take over the value with
Ok
(4) when the pressure stops rising.
5. Take over the settings with
save
(5). The calculated calibration coefficients are displayed.
