The example illustrated gives rise to the following values for a dew-point
temperature of 70 °C:
- Minimum gas sampling hose temperature = 87 °C
- Ideal gas sampling hose temperature = 100 °C
- Maximum gas sampling hose temperature = 120 °C

The gas sampling hose temperature is adjusted within the proportional range
in proportion to the deviation from the setpoint value so that it can move to-
wards this value quickly. The proportional range is factory-set to 3%.

You can define a target gas sampling hose temperature and the equipment
will automatically monitor the adherence to this target. If the actual gas sam-
pling hose temperature deviates by more than

10 °C from the target tem-
perature, a fault message is output.

5.2.3 Programming the pump control
The delivery rate of the water pump must be set in such a way that there is
always excess water that flows out of the measuring cell and guarantees the
self-cleaning effect of the humidity sensor. You should then see the water
dripping off at the outlet connection.
The pump operates intermittently. The delivery rate is modified by means of
the length of the breaks (pauses) between the intervals.
The break is factory-set to 30 intervals. This time is sufficient for standard
applications. In the case of dry gas or a large quantity of dirt, you can in-
crease the delivery rate by shortening the break.
