 Press the [OK] key to start the channel selection.
In the case of the CO channel there is a 2-stage calibration routine:
2
The zero calibration takes place first and is then followed by the span calibration.
– The display shows the gas of the first measuring channel, e.g. » CH
 Press the [OK] key to start the adjustment function of this measuring channel,
or use the [ + ] key to select another measuring channel (O
CO - ppm, etc.).
– The test gas concentration is displayed.
 Press the [ OK ] key to confirm the test gas concentration or use the [ + ] key
to change the test gas concentration and complete the process by pressing
the [ OK ] key.
– The measurement value flashes.
 Open the test gas cylinder valve to let gas flow over the sensor with a
volume flow of 0.5 l/min.
– The displayed, flashing measurement value changes to the value according
to the supplied test gas.
When the displayed measurement value is stable (after at least 120 seconds):
 Press the [ OK ] key to perform the adjustment.
– The display containing the current gas concentration changes with the
display » OK «.
 Press the [ OK ] key or wait for approx. 5 seconds to end the adjustment of
this measuring channel.
– The next measuring channel is displayed for adjustment if necessary.
– After the adjustment of the last measuring channel, the instrument changes
to the measuring mode.
 Close the test gas cylinder valve and remove the instrument from the
calibration cradle.
If a fault has occurred during the span calibration:
– The fault message » « appears and »
respective sensor instead of the measured value.
 In this case, repeat the calibration.
