F.2 Sensor settings

It is possible to set an NO
(dilution/disconnect). The actual calibration data and the status of the sensors can be
displayed. Recalibration can be carried out.
Calling up the function:

Setting sensor protection:
To extend the measuring range and protect the sensors against overloads, you can set
thresholds which, when exceeded, activate sensor protection. Thresholds for a variety
of parameters can be set, depending on the sensors that are connected.

Measurement CO (H2-compensated) sensor:
In order to protect the sensor and for a longer sensor life, we recommend that in
measurements with unexpectedly high CO concentrations (more than 1,000ppm),
the CO sensor is installed in slot 2, and that the threshold of the CO sensor protecti-
on is set to 1,000ppm. From a CO concnetration of 1,000ppm, dilution with a factor
of 5 is automatically activated.
This setting can also be made if H2 concentrations of more than 1,000ppm are to be
expected.
Display ppm/hour counter (active only when sensors with exchangeable filters are
used):
For those sensors which have an exchangeable chemical filter for neutralizing cross-ga-
ses, a ppm/hour counter is available.
