9. Press to confirm the test gas concentration, or use to change the test
gas concentration and confirm with . The measured value flashes.
10. Open the test gas cylinder valve, the volume flow must be 0.5 L/min.
11. Wait until the displayed measured value is stable then confirm with .
The display containing the current gas concentration changes with the
display OK.
12. Press .
● Select to confirm the measured value. The next measuring channel is
displayed for calibration, if necessary. After the last measuring channel
has been calibrated, the gas detector changes to measuring mode.
● Select to discard the measured value and to return to the measuring
channel selection.
● Select to return to the measured value.
13. After successful single-gas calibration, close the test gas cylinder valve and
remove the gas detector from the calibration adapter.
Further steps
If an error occurred during single-gas calibration, the fault message X is
displayed and -- is displayed for the affected measuring channel instead of the
measured value. In this case, repeat the single-gas calibration or replace the
sensor, if necessary.
For mixed gas and cross calibration, see the technical manual.
5.7 Charging the battery
To protect the battery, charge only in the temperature range of 5 to 35 °C.
Outside this temperature range, the charging process is automatically
interrupted and automatically continued after the temperature range has been
reached again. The charging time is typically 4 h. A new NiMH power pack
reaches its full capacity after 3 complete charge/discharge cycles. Never store
the gas detector for extended periods without being connected to a power
source (maximum of 6 months) because the internal buffer battery will drain.
The buffer battery can be replaced if necessary.
