Pump test

NOTICE
i i
Dräger recommends inspection of the seals for
damage before attaching the holder (pump). If
damaged, the holder (pump) must be replaced.
The pump test is performed in the same way as for the
Dräger pump
X-am 1/2/5000. During the pump test, the default
setting acoustic alarm is automatically reduced to
80 dB (A).
The pump LED flashes red/
green, accompanied by a
signal tone.
Tightly close off intake

port or kink the sampling
hose at the beginning of
the hose for at least
2 seconds.
The pump LED lights red.
Unblock the intake flange/
sampling hose.

8.3 Observe the following during measuring
mode with pump
Wait until the flushing time has elapsed.

Before every measurement, flush the Dräger sampling
hose or the Dräger probes with the air sample to be
measured.
A flushing phase is necessary to eliminate or minimise all

effects associated with the use of a sampling hose or a
probe, e. g. absorption in the hose, dead volume.
00833112.eps
The duration of the flushing phase depends on factors such

as type and concentration of the gas or vapour to be
measured, material, length, diameter, and age of the
sampling hose or probe. Generally, when using a sampling
hose (new, dry, clean), a typical flushing time of approx.
3 seconds is required for each metre. This flushing time
applies in addition to the sensor response time (see the
Instructions for Use for the gas detection instrument used).
