After determination of the burning capacity
the next point of the routine is the CO-
measurement. By pressing the curser
<down> a 1-minute calibration cycle starts
for flashing the sensors with fresh air. Dur-
ing calibration cycle the probe must not be
positioned in the combustion tube. After
calibration cycle the CO-content of the
surrounding air can be determined. Use the
probe to check the area around the boiler.
Beside the stored value (press key
<store>) the instrument stores maximum
CO-value of the measurement.
Next point of the routine (curser key
<down>) the CO-value in the combustion
tube of the boiler is determined. For meas-
urement the probe must be positioned in
the combustion tube. Apart from the stored
value the maximum CO-value of the meas-
urement is stored.
After storing the CO-values the next point
are the draught measurements (curser key
<down>). For exact measuring it’s recom-
mended to reset the sensor to zero. Re-
move the draught hose off the instrument
and press <CAL>. The zero point of the
sensor is set now. After the draught has
stabilised it can be stored for later printout
by pressing the key <store>.
At the end of the measurement routine
(curser down) it is checked whether a gas
leakage at the unit could be determined.
Confirmation could be done by using the
key <Enter> (yes / no).
The printout (IR printer required) of all re-
sults of the measurement routine could be
done by pressing <Print>.
