To achieve optimum results of the adjustment we recommend
to consider a warm-up of at least 5 minutes at the appropriate
calibration pressure before any adjustment.
For adjustment first remove the rubber cap above the ADJ button (1), then press
the pushbutton several times by means of a screwdriver or other suitable tool (2)
until the status LED starts quickly flashing orange. After further 3s a slowly
flashing status LED signalizes that the transducer now can be readjusted by
pushing the button once again. Finally insert the rubber cap again.
Readjustment via RS485
Readjustment on atmosphere or zero pressure is also possible by means of
software commands via RS485 interface.
To avoid unintended adjustment the corresponding adjustment point for
atmosphere or zero pressure must be unlocked before the actual adjustment can
be performed.
