4.10 Pairing a gas detector with a
smartphone
®
The Bluetooth function is not part of the technical
suitability test.
The gas detector can be paired with a suitable smartphone via
Bluetooth in order to use the optionally available Dräger CSE
Connect app. The application Dräger CSE Connect is
optimised for the measurement, confined space entry
measurement, and benzene/pre-tube measurement wizards.
For detailed information on pairing via Bluetooth
the instructions for use of the smartphone used.
®
The Bluetooth feature may only be used in countries for
which an approval exists and is not part of the certified
measuring function. Contact Dräger if there are any questions
about availability.
®
The Bluetooth feature has not been tested for operation in
the charging cradle.
Contamination of the gas detector or shielding elements
(e.g. protective cover or CSE case) can reduce the
®
Bluetooth range.
If the Dräger CSE Connect app is used, the gas detector
always has priority with respect to measurements and the gas
measured values and information need to be checked on the
gas detector.
Requirements:
®
– The Bluetooth module is installed in the gas detector.
®
– Bluetooth is activated on the gas detector and the
smartphone.
1. Open the CSE Connect app and select PairingPairing.
2. Select the gas detector X-am 8000.
If several gas detectors are within range, it may be
helpful to identify the desired gas detector based on the
serial number, which is printed on the gas detector. In
older versions of the CSE Connect app, the gas detector
can also be identified by the unique MAC address. For
further information, see the following chapter: "Opening
information", page 39.
3. Accept pairing on the smartphone.
✓ Pairing of the devices is complete.

4.11 Measuring

4.11.1 Special features when measuring with the
pump
NOTICE
Magnetic media may be damaged!
The pump adapter and calibration adapter contain a magnet
which may delete data from a magnetic stripe.
► Do not bring magnetic media (e.g. credit cards) into close
proximity to the pump adapter or calibration adapter.

When using long hoses (from 10 m):
– Ensure strain relief for the weight of the hose.
– Make sure that the intake hose is not kinked.
– The max. hose length is 45 m (with an internal diameter of
3 to 5 mm).
– Use the dust and water separators when taking
measurements with the pump (order no. 83 19 364).
– The nominal flow rate is 0.35 L/min.
– The flow alarm is triggered if the flow rate is <0.3 L/min.
– Following a bump test with aggressive gases (such as
®
also refer to
biogas or chlorine), flush the pump with clean air for
several minutes to extend the service life of the pump.
– A test of the response time with target gas is
recommended.
The wizards are only available for X-am 8000.
For DrägerSensor XXS Cl2, COCl2, O3 as well as amine and
odorants, there is no wizard for clearance measurement, as
these gases cannot be pumped (properly) through tubes. In
addition to the gases listed above, there may also be other
gases for which there are no flushing times available in the
gas detector. There is no confined space entry wizard for
these gases.
Flush the Dräger sampling hose or Dräger probes prior to
each measurement with the gas to be measured. The flushing
phase is necessary to reduce negative effects associated with
the use of a sampling hose or a probe, e.g. gas transport time,
memory effects, dead volume. The duration of the flushing
phase depends on factors such as type and concentration of
the gas or vapour to be measured as well as material, length,
diameter and age of the sampling hose or probe. In addition to
the flushing time, the sensor response time must be observed
(refer to the instructions for use for the DrägerSensors used).
Generally, when using a sampling hose (3 mm internal
diameter, new, dry, clean) with standard gasses, a typical
flushing time of approx. 3 s/m can be assumed.
Example:
The flushing time for oxygen with a 10 m hose is approx.
30 seconds. The assumed sensor response time is approx.
10 seconds in addition. Thus, the overall time before reading
the gas detector is approx. 40 seconds.
A flow-rate alarm is delayed by 10 to 30 seconds depending
on the length of the hose.
X-am 8000: For benzene/pre-tube measurements, the
maximum hose length is 10 m.

4.11.2 Making measurements with the pump

Requirements:
– The gas detector is equipped with a pump and is switched
on.
– All installed sensors are warmed up.
– The gas detector is ready to take measurements.
– The thread port for the pump adapter and calibration
adapter must be clean.
