E.2 Probes/sensors

E.2.1 Connecting probes/sensors
Sensor socket:
Sensor detection is carried out at the sensor socket during the activation process:
Always connect the sensors you need to the measuring instrument before switching
it on or switch the device on and then off again after a change of sensor so that the
correct sensor data are read into the measuring instrument.
Flue gas socket:
Probe/sensor detection at the fl ue gas socket is carried out continuously. It is possib-
le to change the probe/sensor even while the measuring instrument is switched on.
Connecting fl ue gas probes
Connecting other sensors
Connecting the pressure tube
Plug the connector onto the fl ue gas socket and
lock by turning it clockwise gently (bayonet lock).
There must be no more than two extension leads
(0554 1202) between the measuring instrument
and the fl ue gas probe.
Insert the connector of the sensor into the sensor
socket.
Connect the pressure tube/tubes to the connec-
ting nipple/nipples of the pressure socket(s).
