If the final pressure is too high for zero adjustment (>25%
of the F.S.), the zero cannot be reached and the
<STATUS> LED blinks green. If this is the case, activate
the factory setting and adjust the zero again (
→
39).
Operate the gauge for at least 90 minutes under constant
ambient conditions (until the signal is stable).
Briefly press the <ZERO> button with a pin. The zero
adjustment runs automatically. The <ERROR> LED blinks
red until the adjustment (duration
≤
8 s) is completed.
Press the button briefly
max. ø1.1 mm
After zero adjustment, the gauge automatically returns
to the measurement mode.
