Calibration with test-gas ampoules

Use the calibration flask (order no. 68 03 407) – see the

information in the sensor data sheet.
Follow the instructions printed

on the calibration flask and
enclosed with the test-gas
ampoules.
For instruments without an integrated pump:
1 Mount the calibration adapter (with 2 hose sleeves) on the Dräger
X-am 7000 and secure it with the screw.
Plug the adapter (order no.

68 04 620) into the calibration
flask and connect the hoses.
Install an external pump

(such as the hand pump, order
no. 68 01 933) between the
adapter and the Dräger
X-am 7000, noting the correct
direction of gas flow.
Break the test-gas ampoule in

the calibration flask.
Actuate the external pump until

the measured value has settled (see the additional, sensor-
specific information in the related sensor data sheet). Then carry
out calibration.

10.2.3
- Calibration chamber (order
no. 68 02 206) and calibration
adapter (order no. 83 17 989)
with a feed-through for the
calibration chamber. Observe
the instructions for use of the
1
calibration chamber!
Switch off the Dräger

X-am 7000.
1 Remove the sensor grille from
the instrument (secured with
2 screws).
Remove the sealing plate.

2 Remove with the aid of the
00923727_1.eps
sensor grille
3 the sealing plate, taking care
not to damage the sensor
membrane!
For calibration for vapours or
solvents, fit new sensor
membrane on CatEx and IR
Ex sensors in order to ensure
68 07 407
that the sensor membranes
68 04 620
are clean.
4 Pull out the CatEx sensor and
insert the calibration adapter
(order no. 83 17 989) in its
place, noting the coding of the
68 01 933
plug connector!
