– 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 calibration.
– 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 calibration of this
measuring channel.
– The next measuring channel may appear for calibration.
– After the calibration of the last measuring channel, the instrument changes to
measuring mode.
 Close the test gas cylinder valve and remove the instrument from the
calibration cradle.
If a fault occurred during the span calibration:
– The fault message » « appears and »
respective sensor instead of the measured value.
 In this case, repeat the calibration.
 If necessary, replace the sensor.
Notice for the adjustment of the ex-channel to nonane as a measuring gas:
– When calibrating the Ex channel, propane can be used as a substitute for
the test gas.
– When using propane to adjust the ex-channel to nonane, the display must
be set to twice the used test gas concentration.
Notice for use in underground mining:
– When calibrating the Ex channel to methane as the measured gas,
the indication on the instrument must be set to a value 5 % (relative) higher
than the test gas concentration used.
Cleaning
