Dräger X-pid 9000 Notice D'utilisation page 27

Requirements:
– Suitable test gas cylinder with standard 0.5 mL min
gassing adapter fitted.
– The sensor unit is turned on, connected to the mobile app and the start-up
phase, heat-up phase and temperature stabilisation have been completed.
1. Connect the gas cylinder to the sensor unit using the gassing adapter. The
water and dust filter must be fitted.
2. Start the calibration in the mobile app and follow the instructions. The user is
automatically guided through the calibration process and notified when the
test gas needs to be applied.
If the calibration is not successful:
– The mobile app will display the calibration as failed.
– Repeat the calibration, and have the sensor unit tested by maintenance
personnel as appropriate.
– Check the test gas and follow the instructions in the mobile app.
For further information, see the technical manual.
5.4 Carrying out a fresh air calibration
Fresh air calibration is only available on the Dräger X-pid 9x00.
Observe the following information for the fresh air calibration:
– The zero-point of the Seeker mode can also be calibrated in the field in
contaminated atmospheres by generating internal fresh air.
– Fresh air calibration is not a substitute for calibration, where the sensitivity of
the Seeker is calibrated in addition to the zero-point. For further information,
see the following chapter: "Carrying out a calibration", page 26.
– A fresh air calibration has no effect on the Analysis mode.
1. Start the fresh air calibration in the Calibrate view of the mobile app and
follow the instructions. During the fresh air calibration, you need to hold your
finger in front of the water and dust filter in order to reverse the internal gas
flows and conduct filtered air to the Seeker PID.
Fresh air calibrations are automatically saved and can be viewed in the archive.
The zero-point is displayed in mV.

5.5 Charging the sensor unit
WARNING
Risk of explosion!
The chargers are not constructed in accordance with regulations for wet
weather conditions and explosion protection.
► Do not charge in explosion-hazard areas!
► Use the battery charger supplied (type FW8001/12, order no. 6851844 or
type GTM96180-1217.9-5.9, order no. 6850018) with magnetic connector to
charge the sensor unit.
► Ambient temperature during the charging process: +5 to +35 °C.
WARNING
Health hazard!
Magnets can affect the function of pacemakers and implantable cardioverter
defibrillators (e.g. actuating the reed switch).
► Observe a minimum distance of 20 cm between the magnet connection and
the implanted devices to avoid malfunctions and health hazards.
The rechargeable battery cannot be changed. If the rechargeable battery is
faulty, it can be replaced during maintenance.
– The sensor unit can be charged whether turned on or off.
– When turned on and connected, the charging status of the sensor unit can
be displayed in the mobile app.
– When turned off, the status LED pulses during the charging process (
When the sensor unit is fully charged, the status LED also blinks twice
between the pulses ( ).
The typical charging time is 5 hours from complete discharge to full charge.
Never store the device for extended periods (max. 2 months) without a power
supply to avoid a complete discharge of the battery.
5.6 Configuration
Only trained personnel are permitted to carry out modifications to the device
configuration.
