Intended Use; Explanation Of Symbols - Dräger Quaestor 5000 Notice D'utilisation

Description
The following accessories are included with the Dräger
Quaestor 7000:
External microphone

The microphone registers the signal of the acoustic whistle
when inspecting a compressed air breathing apparatus or
rebreathing apparatus.
Bracket for gauge or Bodyguard

The bracket is available as an option for the Dräger
Quaestor 5000.
The following accessories are available as options both for the
Dräger Quaestor 5000 and for the Dräger Quaestor 7000:
200 bar-Option

If the test device is to be operated at a test pressure of
200 bar, the 200 bar option must be connected. In addition,
it is only permitted for there to be a pressure of 200 bar on
the high pressure inlet. Dräger recommends connecting
pressure reducer R 57 584 to the high pressure inlet.
If the pressure in the test device is higher than 200 bar,
the air is released without damaging the respiratory
protective device.
Compressed air breathing apparatus bracket

for the upright positioning of the apparatus during the test
Adapter for mask/helmet combinations

for mounting the mask onto the test head without head
harness
1
QSI -Box

for sound isolation of the residual pressure warning from
gauge or Bodyguard
Breathing adapter

for positive leak test conforming to vfdb 0804
Hood

to protect the test device against dust and water

Intended use

The basic version of the Dräger Quaestor 5000/7000 can be
used to test compressed air breathing apparatus, compressed
air hose breathing respirators and full face masks. Depending
on the device version, the tests can be performed on the
following components:
Full face mask:

Positive pressure leak test

Negative pressure leak test

Opening pressure of the exhalation valve

Head-up display test (manual)

On the lung demand valve:

Positive pressure leak test

Negative pressure leak test

Opening pressure

Switching pressure

Static positive pressure

Metering valve test

Breathing test (test of the dynamic breathing resistance)

1 QSI = Quaestor Sound Isolation
2 Only if a compressed air breathing apparatus test is being
performed
16
2
On the compressed air breathing apparatus

Static medium pressure

Increase in the medium pressure

High pressure leak test

Comparative test for pressure gauge

Head-up display test (manual)

Response pressure of the acoustic warning device

Breathing test (test of the dynamic breathing

resistance)
On the chemical protection suit

Leak tightness of the chemical protection suit

Leak tightness of suit valves

Chemical protection suits can be tested in a fully automated
way using the Dräger
Quaestor 5000 can be used to perform the measurements via
the measuring point in the eye, however the protection suit
must be inflated using a compressed air gun.
Both test devices can be expanded using modules that can be
used to test closed-circuit breathing apparatus and the safety
valve on pressure reducers. The Dräger Quaestor 7000 can
also have a module added that can be used to test diving
apparatus.
The tests are conducted in accordance with the VFDB
Directive 0804 and for the compressed air breathing apparatus
also in accordance with EN 137.
