WARNING
Before making safety-related measurements, check the
adjustment and adjust as needed, and check all alarm
elements. If there are national regulations, the bump test must
be performed according to these regulations. Faulty
adjustment can lead to incorrect measurement results and,
therefore, also cause severe health risks.

.
– The instrument will perform a self test.
– The software version and the gas name are displayed.
– The A1 and A2 alarm limits are displayed.
– If the calibration interval function is activated the days
remaining until the next calibration, e.g., » CAL « then » 20 «
are displayed.
– If the bump test interval function is activated, the time until
the bump test interval elapses is displayed in days, e.g., » bt
« then » 123 «.
– After max. 20 seconds the gas concentration is displayed
and the instrument is ready for use.
4.2
Before entering a working place
– After turning the instrument on, the actual measurement
value will normally be shown in the display.
– Check for the notice icon
[!]
. When lit, it is recommended that
you perform a bump test as described in chapter 4.3.
– Clip the instrument to clothing before working in or near
potential gas hazards.
4.3
Performing a "bump test" with gas
– Prepare a Dräger test gas cylinder with 0.5 l/min and a gas
concentration higher than the alarm threshold to be tested.
– Connect Dräger Pac 7000 and the test gas cylinder to the
calibration adapter or connect the device to the Dräger Bump
Test Station.
– To enter the bump test mode, press the
[+]
3 times within
3 seconds. The instrument beeps twice, quickly. The notice
icon
[!]
begins to flash.
Notice
All display segments are lit. Next, the LED, Alarm and
Vibrating alarm are activated in sequence. Check these
before each use.
WARNING
For the O2 sensor: after the first turning on of the instrument,
a sensor warm up time of up to 15 minutes is needed. The
gas value flashes until the warm up time has passed.
WARNING
The gas opening is equipped with a dust and water filter. This
filter protects the sensor against dust and water. Do not
destroy the filter. Contamination may change the properties of
the dust and water filter. Replace destroyed or clogged filter
immediately.
Ensure that the gas opening is not covered and that the
device is also near to your breathing area. Otherwise the
device will not work properly.
CAUTION
Risk to health! Test gas must not be inhaled. Observe the
hazard warnings of the relevant safety data sheets.
Notice
With Dräger Bump Test Station the unit can be configured to
automatically start the bump test without pressing any key. In
this case the manual start of the bump test is deactivated.
