Maintenance
Check the zero point every 6:th month.
Zero setting of the pressure transmitter
Disconnect the pressure tubes or set the manifold
valve in the calibration position.
With the startmenu displayed, press simultanously
both the keys ¹¸ until the display shows:
ZERO OFFSET
Release the keys when the display shows:
ZERO OFFSET
ADJUSTING
When zero set is ready, the unit displays
ZERO OFFSET DONE
and automatically returns to start menu.
