E.2 Probes/sensors

E.2.1 Connecting probes/sensors
Sensor s s ocket:
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 g g as s s ocket:
Probe/sensor detection at the flue gas socket is carried out continuously. It is possi-
ble to change the probe/sensor even while the measuring instrument is switched on.
Connecting flue gas probes
Connecting other sensors
Connecting the pressure tube
Plug the connector onto the flue gas socket and
lock by turning it clockwise gently (bayonet lock).
There must be no more than two extension leads
(0554 1201) between the measuring instrument
and the flue gas probe.
Insert the connector of the sensor into the sensor
socket.
Pressure sockets p+ and p- can only be used with
instruments offering the "Pressure/flow speed meas-
urement" option.
Connect the pressure tube/tubes to the connect-
ing nipple/nipples of the pressure socket(s).
