Carrying out the function test with gas (Bump Test)
In the case of a manual function test the effect of the H
taken into account accordingly.
A potentially activated H added signal is automatically temporarily deactivated

during a manual calibration, a PC calibration or an automatic Bump Test for the
relevant duration.
The automatic function test with the Bump Test Station is described in the
Instructions for Use of the Bump Test Sation and in the Technical Handbook.
Prepare a test gas cylinder, the volume flow must be 0.5 l/min and the gas
concentration must be higher than the alarm setpoint concentration to be
tested.
Connect the test gas cylinder to the calibration cradle (order no. 83 18 752).
Risk to health! Do not inhale the test gas.
Observe the hazard warnings of the relevant safety data sheets.
Switch on the instrument and insert it into the calibration cradle– press
downwards until it engages.
Open the test gas cylinder valve to let test gas flow over the sensors.
Wait until the instrument displays the test gas concentration with sufficient
tolerance – E. g.
1)
IR Ex: ±20 %
1)
IR CO : ±20 %
2
1)
O : ±0.6 vol. %
2
1)
TOX: ±20 %
– If the alarm setpoints are exceeded, the instrument displays the gas
concentration in alternation with » A1 « or » A2 « depending on the test gas
concentration.
Close the test gas cylinder valve and remove the instrument from the
calibration cradle.
If the displays are outside of the above-mentioned ranges:
Have the instrument calibrated by the service personnel.
1) Upon application of the Dräger mixed gas (order no. 68 11 132) the displays should be within
this range.

Carrying out the fresh air calibration
Calibrate the instrument to fresh air, free of measured gases or other interfering
gases. During the fresh air calibration the zero point of all sensors (with the
exception of the DrägerSensors XXS O
In the case of the DrägerSensor XXS O
The fresh air calibration / zero point adjustment is not supported by the
DrägerSensor Dual IR-CO and the DrägerSensor IR-CO

calibration / adjustment of these sensors can be conducted using the Dräger
CC-Vision PC software. To do so, a suitable zero gas that is free of carbon
dioxide (e.g. N ) should be used.

Switch on the instrument.
Press the [ + ] key 3 times, the symbol for fresh air calibration »
appears.
Press the [ OK ] key to start the fresh air calibration function.
– The measured values flash.
When the measured values have stabilized:
Press the [ OK ] key to perform the calibration.
– The display containing the current gas concentration changes with the
display» OK «.
Press the [ OK ] key to exit the calibration function or wait for approx.
5 seconds.
If a fault has occurred during the fresh air calibration:
