If the final pressure is too high for zero adjustment (>25%
of the F.S.), the zero cannot be reached and the
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 button with a pin. The zero
adjustment runs automatically. The 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.
