Maintenance intervals
The device should be inspected and maintained by suitably qualified persons every six
months (consult: EN 60079-29-2 – Gas measuring device - Selection, installation, use and
maintenance of apparatus for the measurement of combustible gases or 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 and
national regulations). We recommend that you calibrate all channels after 6 months.
● Depending on device configuration:
Replace the alkaline batteries or charge the battery – refer to page 42 to page 43 – after
each use, at the latest after the battery alarm has been triggered or after 2 weeks.
● Device calibration – page 35.
— In regular intervals, according to the used sensors and the operating conditions. For sen-
sor-specific calibration data, refer to the Instructions for Use of the used sensors
1)
.
— Before you carry out safety-related relevant measurements, the zero point and sensitivity
of the devices should be tested in accordance with national regulations.
● Inspection by suitably qualified persons – every year.
— The inspection intervals must be established in each individual case and shortened if ne-
cessary, depending on technical safety considerations, engineering conditions and the
technical requirements of the equipment.
— We recommend that a service agreement be concluded with Dräger Safety and that re-
pairs also be carried out by them.
● Replace the sensors, page 46 – if necessary, when it is not possible to calibrate the sen-
sors anymore.
1) The Instructions for Use of the used sensors are supplied with the device on CD.
