This service is used for activating the adjustment of the Piezo sensor to the
Capacitance diaphragm sensor via Profibus.
The atmosphere pressure sensor can be adjusted to the internal (vacuum cham-
ber) Capacitance diaphragm sensor.
If you want to adjust the atmosphere pressure sensor to the Capacitance
diaphragm sensor, proceed as follows:
n
Vent the vacuum system to atmospheric pressure
o
Send the "Release User ATM adjust" command
p
Perform the "User ATM adjust command" as specified below.
After this procedure, the atmosphere pressure sensor will give the same pressure
value as the Capacitance diaphragm sensor at atmospheric pressure.
