Maintenance

For inspection and maintenance, see e.g.:
– EN/IEC 60079-29-2 – Gas detectors - Selection, installation, use and

maintenance of detectors for flammable gases and oxygen

– EN 45544-4 – Electrical apparatus used for the direct detection and direct

concentration measurement of toxic gases and vapours - Part 4: Guide for

selection, installation, use and maintenance

– National regulations

6.2

Calibration intervals

Observe the relevant specifications in the DrägerSensor

®

& Gas Detectors Manual

and in the instructions for use/data sheets of the Dräger sensors installed.
Recommended calibration intervals for DrägerSensors:

National regulations may stipulate shorter intervals and must be applied.

6.3

Test gases

Test gas properties (e.g. relative humidity, concentration) can be found in the

relevant sensor data sheet.
The relative humidity of the test gas is not relevant for O

2

sensors.

Different test gases are used depending on the type of calibration.

6.4

Performing the bump test

The bump test can be performed as follows:
– Manual bump test
– Bump test with the bump test station
– Bump test with X-dock

The Dräger CC-Vision PC software can be used to configure whether a quick or

advanced bump test should be performed with the menu or in the bump test station.

Dräger recommends using the extended bump test for cross calibrations (see the

Dräger X-dock instructions for use).

For the CatEx sensor, we recommend methane as the test gas, including for cross

calibration, if methane is expected in the target application.

1) The recommended calibration interval can be extended to 12 months if it is ensured that an

advanced bump test (tolerance: max. ±20 %) is carried out and passed before use in safety-

relevant measurements. The advanced bump test checks the existing sensitivity.
