Connecting probes / sensors

Sensor detection at the sensor socket takes place during the
activation process.
✓ Sensors that are required must always be connected before the
measuring instrument is switched on, or the instrument must be
switched off and then on again after the sensor has been
changed, so that the correct data can be read into the
measuring instrument.
Probe/sensor detection at the flue gas socket is carried out
continuously. It is possible to change the probe/sensor even while
the measuring instrument is switched on.
Connecting flue gas probes / gas pressure adapters /
temperature adapters
> Insert the connector plug into the flue gas socket and lock by
slightly turning it clockwise (bayonet lock).
Connecting other sensors
> Insert the connector plug of the probe into the probe socket.
There must be no more than one extension lead (0554
1201) between measuring instrument and flue gas probe.
