The push button <FULL SCALE> is also used for the zero point adjustment
(
® Illustration in "Adjustment at Atmospheric Pressure").
 Operate gauge for approx. 10 minutes at a pressure of 1×10
-4
mbar.
 Insert the pin through the opening marked <FULL SCALE> and push the
button inside for at least 2 s.
The adjustment is done automatically and ends after 2 minutes.
The zero point of the gauge is now adjusted.
In the event of a fault or a complete failure of the output signal, the gauge can
easily be checked.
· Voltmeter / ohmmeter
· Allen key, size 2.5 mm
· Spare sensor (if the sensor is faulty)
The output signal is available at the sensor cable connector (Pin 2 and Pin 12).
In case of an error, it may be helpful to just turn off the mains supply and
turn it on again after 5 s.
