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.
Connecting tthe pprobes:
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.
Connecting tthe ssensor:
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.
Using the flue gas probe
Checking tthe tthermocouple:
The thermocouple of the flue gas probe must not lie against the probe cage.
Check before use. Bend the thermocouple
back if necessary.
Page 13

RGS
Aligning tthe fflue ggas pprobe:
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).

must be in the open air during the zeroing phase!
Performing the measurement
Measuring:
The steps described in the chapter Preparing for measurement have
been completed.
Let by and tightness function: The Diff Press Kit (0554 1203) must be
connected.
Warning! Risk of explosion due to dangerous mixture of gases!
Make sure there are no leaks between the sampling point and the
measuring instrument.
Do not smoke or use naked flames during measurement.
Draught function: The pressure sensors are zeroed when the Draught
function is started (length of time: 5 s). The measuring instrument must
not be pressurised during zeroing!
To help position the flue gas probe in the centre of the flow (area of the
Page 15
Using the product 15
highest flue gas temperature), the flue gas temperature measured is
shown graphically.
Do not measure for longer than 5 minutes, as the readings may fall
outside of the tolerances due to a possible drift of the pressure sensor.
Smoke/Oild function: Only available if a liquid fuel has been activated.
Diff-temp. function: The differential temperature set (0554 1208)
must be connected. The ambient air sensor must be unplugged (located
bottom left of unit) before connecting the T1 sensor. Be aware that the
connector is a firm fit, when disconnecting.
The differential temperature is calculated from T1 - T2.
Diff-press function: The gas pressure set (0554 1203) must be connected.
The pressure sensors are zeroed when the Diff.-press function is started
(length of time: 5 s). The measuring instrument must not be pressurised
during zeroing!
Do not measure for longer than 5 min, as a drift of the pressure sensor
may result in readings outside the tolerance limits.
Ambient CO: When the measuring cells are first started after the measuring
instrument is switched on, they are zeroed (length of time: 30 s).
Exception: The Flue gas function has already been called up.
Any connected probe must be in the open air during the zeroing phase!

Condensate trap
The fill level of the condensate trap can be read from the markings on the
condensate trap.
Emptying tthe ccondensate ttrap
Flue Gas condensate consists of a weak mix of acids. Avoid contact with the
skin. Make sure that the condensate does not run over the housing.
Caution! Failure to empty the condensate trap when the fill level is
reached results in condensate entering the sensors and pump. This
voids the warranty and results in costly repairs and replacements.
Do not empty the condensate trap while the flue gas pump is in operation!
1 Keep measuring instrument in an upright
position (condensate outlet pointing upwards).
2 Open the condensate outlet on the
condensate trap: pull out approx. 7 mm to
the stop.
3 Let the condensate run out into a sink.
4 Mop up any remaining drops on the
condensate outlet using a cloth.
5 Close the condensate outlet.
The condensate outlet must be completely
closed, otherwise measuring errors could occur if external air gets in. It is
advisable to empty water trap at regular intervals, (preferably daily).
