Adjusting The Sensitivity For An Individual Measuring Channel - Dräger X-am 5600 Instrucciones De Uso

Have the instrument adjusted by the service personnel.

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.
After the bump test (menu), the display shows a printer icon even if there is no
printer connected to the bump test station.
Calibration
Calibration may not be possible due to instrument and channel errors.
A potentially activated H offsetting is automatically temporarily deactivated

during a manual calibration, a PC calibration or an automatic Bump Test for the
relevant duration.
Dräger recommends using the extended bump test for cross calibrations
(Dräger X-dock technical manual).
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 and the CO

The fresh-gas adjustment/zero-point adjustment is not supported by the CO
channel of the infrared sensor and the XXS O
sensors can be made with the Dräger CC Vision PC software. A suitable zero
gas free from carbon dioxide and ozone (e.g. N

– 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.
