Carry Out Manual Bump Test - Dräger X-am 5600 Instrucciones De Uso

Carry out manual bump test

In the case of a manual function test the effect of the H
taken into account accordingly.
A potentially activated H offsetting is automatically temporarily deactivated

during a manual calibration, a PC calibration or an automatic Bump Test for the
relevant duration.
The automatic functional test with the Bump Test Station is described in the
instructions for use for the bump test station and in the Technical Manual.
 Prepare a test gas cylinder, the volume flow must be 0.5 l/min and the gas
concentration must be higher than the alarm threshold concentration to be
tested.
 Connect the test gas cylinder to the calibration cradle (order no. 83 18 752).
Risk to health! Never 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.
IR Ex: ±20 % of the test gas concentration
IR CO : ±20 % of the test gas concentration

O : ±0.6 vol. %

TOX: ±20 % of the test gas concentration
– If the alarm thresholds are exceeded, the instrument displays the gas
concentration in alternation with »A1« oder »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:
1) Upon application of the Dräger mixed gas (order no. 68 11 132) the displays should be within
this range.

To check the measured value response times, apply t90 test gas to the X-am
via the calibration cradle. Check the results in accordance with the details in the
table from page 14 until 90 % of the end display is reached.
After the bump test, the display shows a printer icon even if there is no printer
connected to the bump test station.
Adjustment
Adjustment may not be possible due to instrument and channel errors.

Carrying out the fresh air adjustment
Adjust 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
