Preparing for measurement

Connecting probes/sensors
The instrument needs to detect which probes or sensors are connected, before
switch on. If you fail to do this simply turn off instrument connect probe and
re-start unit.

If no ambient air temperature sensor is connected, the temperature
measured by the thermocouple of the flue gas probe during the zeroing
phase is used as the ambient air temperature. All dependent parameters
are calculated using this value. This method of measuring ambient air
temperature is sufficient for systems dependent on ambient air. However,
ensure that the flue gas probe is near the intake duct of the burner during
the zeroing phase.
If an ambient air temperature sensor is connected, the ambient air
temperature is measured continuously by this sensor.
Insert the connector of the sensor into the sensor socket.

C C h h e e c c k k i i n n g g t t h h e e t t h h e e r r m m o o c c o o u u p p l l e e : :
The thermocouple of the flue gas probe must not lie against the probe cage.
Insert the connector into the flue gas
socket and lock by turning it clockwise
gently (bayonet lock).
There must be no more than one extension
lead (0554 1201) between the measuring
instrument and the flue gas probe.
Check before use. Bend the thermocouple
back if necessary.
A A l l i i g g n n i i n n g g t t h h e e f f l l u u e e g g a a s s p p r r o o b b e e : :
The flue gas must be able to flow freely past the thermocouple.
Align the probe by turning it as required.
The tip of the probe must be in the centre of the flue gas flow.
Align the flue gas probe in the flue gas duct
so that the tip is in the centre of the flow
(area of the highest flue gas temperature).
