Performing the bump test

3.3.1 Manual testing without documentation of results in
the instrument memory
NOTICE
i i
Sensor-specific features affecting the bump test are
described in the respective sensor data sheets.
1. Prepare a test gas source (e.g., cylinder, permeation oven);
the volume flow must be 0.5 L/min and the gas
concentration must be higher than the alarm threshold
concentration to be tested.
2. Fit the calibration adapter
(68 06 291) to the sensor
cap.
3. Connect the test gas
source to the calibration
adapter.
4. Vent the test gas into
a fume cupboard or into
the open air (with a hose
connected to the second
connector of the calibration
adapter).
WARNING
!
Never inhale the test gas. Danger to health!
Observe the hazard warnings in the relevant Safety
Data Sheets.
5. Switch on the instrument.
6. Open the valve on the test gas source to let test gas flow
over the sensor.
7. Recommendation: Wait until the instrument displays the
test gas concentration with sufficient tolerance.
However, wait at least until alarm threshold A1 or A2 has
been exceeded.
If the alarm thresholds are exceeded, the instrument

displays the gas concentration in alternation with » A1 «
or » A2 « depending on the test gas concentration.
8. Close the valve on the test gas source.
If the concentration has now fallen under the A1 alarm

threshold:
Acknowledge the alarm.

If the displays are outside of the above-mentioned ranges:

Calibrate the instrument, see "Calibrating the instrument"

on page 15.
Bump test with documentation of results in
3.3.2
the instrument memory.
The "Quick bump test" or the "Extended bump test" is

selected using the Dräger CC Vision PC software. The
"Quick bump test" checks whether the gas concentration
has exceeded the Alarm 1 threshold (with oxygen, the
check is whether the concentration has fallen below the
Alarm 1 threshold). The "Extended bump test" checks
whether the gas concentration has exceeded the Alarm 1
threshold (with oxygen, the check is whether the
concentration has fallen below the Alarm 1 threshold) and
whether the gas concentration has reached the preset
bump test concentration.
Setting on delivery: Quick bump test.

8. Open the valve on the test
gas source to let test gas
flow over the sensor.
If gas concentration

If a gas alarm (Quick

the instrument memory.
9. Close the valve on the test
gas source.
If the concentration has now fallen below the A1 alarm

threshold, the instrument returns to the measuring mode.
If the set bump test concentration is not reached after a

sensor-specific time interval, an instrument error is
generated.
