To use the semi-automatic calibration system, connect the compressed air (instrument
air) for offset calibration and the test gas manually to the probe one after the other and
set the required quantity.
** If no instrument air is available for the reference air, an optional pump unit is
available.
The pressure sensors are integrated in the probe connection box on the head of the
probe. The differential pressure sensor monitors the reference air, the absolute
pressure sensor monitors the rise in pressure in the preliminary filter during
calibration.
Electrical und pneumatic connections see chapter 10.3 and 10.4.
