
Vent the test gas into a fume cupboard or into the open air (with a hose
connected to the second connector of the calibration cradle).

Switch on the instrument and insert it into the calibration cradle.

Press the [+] key and keep it pressed for 5 seconds to open the calibration
menu, enter the password (password on delivery = 001).

Use the [+] key to select the single-gas adjustment function. The symbol
for span calibration » « flashes.

Press the [OK] key to start the channel selection.
– The display shows the gas of the first measuring channel, e.g. »CH
4
LEL« .

Press the [OK] key to start the adjustment function of this measuring channel,
or use the [+] key to select another measuring channel (O
2
- Vol.-%, H
2
S - ppm,
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:
WARNING
Risk to health! Never inhale the test gas.
Observe the hazard warnings of the relevant Safety Data Sheets.
NOTICE
In the case of the CO
2
channel there is a 2-stage calibration routine:
The zero calibration takes place first and is then followed by the span calibration.
– The fault message » « appears and » « is displayed for the
respective sensor instead of the measured value.

In this case, repeat the calibration.

Change the sensor if necessary.
Cleaning
The instrument does not need any special care.

Dirt and deposits can be removed from the instrument by washing it with
cold water. A sponge can be used for wiping if necessary.

Carefully dry the instrument with a cloth.

Test gas properties (such as relative humidity, concentration, etc.) can be found
on the corresponding data sheet of the sensor. The relative humidity is not
relevant for the O2 sensor. Always use dry test gas.
Storage

Dräger recommends storing the instrument in the charger module
(order no. 83 18 639).

Dräger recommends checking the charge of the power supply at least every
three weeks if the instrument is not stored in the charger module.
