Calibration
When SEARCH
(lower point)
is activated, evacuation is to the lower point. If the pressure
does not fall any further, the value can be entered by using a comparison measurement de-
vice and confirmed with OK. The system is vented and the ambient barometric pressure en-
tered as the upper point. Do not confirm until the value has been established.
If the controller is integrated in a complete system or pump system (LVS), evacuation and
venting take place automatically when the stated buttons are pressed.
The calculated correction values are displayed and can be stored with Save.
CAUTION !
Ensure that the set pressure is also present at the sensor.
