Have the instrument adjusted by the service personnel.
Calibration
Calibration may not be possible due to instrument and channel errors.
Carrying out the fresh air calibration
Calibrate the instrument to fresh air, free of measured gases or other interfering
gases. During the fresh air adjustment, the zero point of all sensors (with the
exception of the XXS O
2
and the CO
2
channel of the infrared sensor) is set to 0.
In the case of the XXS O
2
, the display is set to 20.9 vol. %.
Switch on instrument.
Press the
[+]
key three times to display the icon for fresh air calibration
» «
.
Press the
[OK]
key to start the fresh air calibration.
–
The measured values flash.
When the measured values have stabilized:
NOTICE
To check the measured value response times, apply t90 test gas to the X-am
via the calibration cradle. Check the results in accordance with the information
in the table in the enclosed supplementary documentation (order no.
90 33 890) until 90 % of the end display is reached.
NOTICE
After the bump test (menu), the display shows a printer icon even if there is no
printer connected to the bump test
station.
NOTICE
A potentially activated H
2
offsetting is automatically temporarily deactivated
during a manual calibration, a PC calibration or an automatic Bump Test for the
relevant duration.
NOTICE
Dräger recommends using the extended bump test for cross calibrations
(Dräger X-dock technical manual).
NOTICE
The fresh-gas adjustment/zero-point adjustment is not supported by the CO
2
channel of the infrared sensor and the XXS O
3
. A zero-point calibration of these
sensors can be made with the Dräger CC Vision PC software. A suitable zero
gas free from carbon dioxide and ozone (e.g. N
2
) must be used.
Press the
[OK]
key to perform the fresh air calibration.
–
The display containing the current gas concentration changes with the
display
»OK«
.
Press the
[OK]
key to exit the fresh air calibration function or wait for
approx. 5 seconds.
If a fault has occurred during the fresh air calibration:
–
The fault message
»
«
appears and »
« is displayed for the
respective sensor instead of the measured value.
In this case, repeat the fresh air calibration. If necessary, have the sensor
replaced by qualified personnel.
Adjusting the sensitivity for an individual
measuring channel
–
The span calibration can be carried out selectively for individual sensors.
–
In the case of the span calibration, the sensitivity of the selected sensor is
set to the value of the test gas used.
–
Use a standard test gas.
–
Allowed test gas concentration:
Connect the test gas cylinder with the calibration cradle.
