| Commissioning the test unit
– 200 bar option
If the test unit is to be operated at a test pressure of
200 bar, the 200-bar option must be connected. In
addition, the high-pressure inlet must be at a
pressure of only 200 bar. Dräger recommends that
the pressure reducer R 57 584 is connected to the
high-pressure inlet.
If the pressure in the test unit is higher than 200 bar,
the air is released without damaging the breathing
safety product.
– Self-contained breathing apparatus bracket
This accessory ensures that the self-contained
breathing apparatus is positioned upright during the
test.
– Adapter for mask/helmet combinations
This accessory can be used to mount the mask onto
the test head without a head harness.
– QSI1)-Box
This accessory provides sound insulation for the
residual pressure warning from the pressure gauge
or Bodyguard.
– Breathing adapter (Dräger Quaestor 6000/8000)
For performing positive pressure leak tests in
accordance with vfdb 0840-02.
– Adapter for lung demand valves (Quaestor 4000)
3.3 Intended use
The basic version of the Dräger
Quaestor 4000/6000/8000 can be used to test
respiratory protective devices. Depending on the device
version, the following tests can be performed on the
various components:
– On the full face mask:
– Positive pressure-leak test
– Negative pressure-leak test
– Opening pressure of the exhalation valve
– Head-up display test (manual)2)
– On lung demand valves:
– Positive pressure-leak test
– Negative pressure-leak test
– Opening pressure
– Switching pressure
– Static positive pressure
– Balanced piston unit test
– Breathing test (test of the dynamic inhalation
resistance)3)
– On the self-contained breathing apparatus:
– Medium pressure
– Increase in the medium pressure
– High pressure-leak test
– Comparative test for pressure gauge
– Head-up display test (manual)2)
– Response pressure of the acoustic warning
device
– Breathing test (test of the dynamic inhalation
resistance)3)
– On the chemical protective suit:
– Leak tightness of the protective suit
– Leak tightness of the suit valves
Chemical protective suits can be tested in a fully
automated manner using the Dräger Quaestor 8000.
With the Dräger Quaestor 4000/6000, measurements
can be taken via the measuring point in the eye, but the
protective suit must be inflated with a compressed air
pistol and the pressure range must be corrected
manually during the 10-minute settling phase.
The Dräger Quaestor 6000 and 8000 can be expanded
using modules that can be used to test the safety valve
on pressure reducers. The Dräger Quaestor 8000 can
also be expanded to include modules that can be used
to test Dräger's closed-circuit breathing apparatus and
certain diving equipment.
4 Commissioning the test unit
4.1 Instructions on using the test
unit
To ensure that the test unit is operated safety and that
no accidents occur during operation, observe the
following points when working with the test unit:
– The test unit must only be connected to the power
supply using the power supply unit provided.
– Before commissioning, the test unit must be
attached to the workstation using the table mount.
– It is crucial to protect the test unit from the ingress of
water and moisture. Ensure that no moisture from
splash water or leak detection agents can penetrate
into the test unit.
– The housing must only be opened by trained Dräger
personnel.
– The test unit must be calibrated once a year. Retain
the supplied packaging for future shipping.
