Adjustment Of The X-Zone 5500 (Pump Mode) - Dräger X-zone 5500 Gebrauchsanweisung

Operation with pump (optional)
Example:
 In the case of a 10 m sampling hose, the flushing time is
approx. 30 seconds and the sensor response time is in
addition approx. 60 seconds. Therefore, the total time
before reading the gas detection instrument is approx.
90 seconds.
 The flow-rate alarm is delayed by 10 to 30 seconds
depending on the length of the hose.

For the calibration intervals, see the Instructions for
Use/Data Sheet for the sensors used.
9.4.1 Performing the fresh air calibration
X-am 5x00 Calibrate on fresh air, free of measured gases or
other interfering gases. During the fresh air calibration the zero
point of all the sensors (with the exception of the DrägerSensor
XXS O and XXS CO ) is set to 0. With the DrägerSensor XXS

If a mixed gas with another composition is used, the
specified concentration values in the X-am 5x00 must
be changed to the target values of the mixed gas used
using the Dräger CC-Vision PC software.
1. Screw the valve on to the test gas cylinder.
2. Insert the X-am 5x00 in the calibration cradle of the
X-zone 5500 and switch on (see chapter 3.1 on page 45).
3. Press the key and keep it pressed for 5 seconds to open
the calibration menu.

7. Connect the hose from the test gas cylinder to the
X-zone 5500.
8. Vent the test gas into a fume cupboard or into the open air.
The currently displayed measured values start to flash. The

flashing stops after a static measured value has been
reached.
 The calibration is carried out automatically.
The displayed measured values change to the values
