Error messages during measurement
Symbols are flashing
CO, and are flashing
During the initialisation phase
CO is flashing
Before switching off
CO are flashing
LOW BAT
Cause / Remedy
1. Flue gas temperature probe not
connected.
2. Temperature probe is not connected properly.
Flue gas temperature and its calculated values are
not measured, the remaining values are listed.
Check the temperature probe connection or insert
new temperature probe.
Admissible operating temperature has been
exceeded. The ambient air changes to non-
permissible values. Adapt to ambient air
temperature.
Measurement of the zero point is not stable. Let
the initialising phase run several times. If this is not
successful, the CO measurement cell is probably
defect.
There is still flue gas in the analyser or very high
concentrations were measured or the initialising
phase is taking longer.
Cause: Insufficient air was rinsed through after the
last measurement or the probe is in the flue gas.
Probe should be brought into contact with
fresh air. If there is still no change after several
runs of the initialising mode the cell is probably
defect or the cell is used up.
The analyser supply voltage is too low.
Recharge rechargeable/battery or connect to
mains.
