6. Maintainance
6.1 General
In view of the significance of the accuracy of
measuring results, the test device must be treated
with care. Dirt must be avoided at all time, especially
at the highpressure connection.
Flushing and cleanless control of the test device
must be made as described in para. 5.2. After
measuring is completed, the test device shell be
stored in the case. The high pressure connection
should be closed with a protective cap.
Functual checks should be made at regular intervals
and if erroneous measurements are suspected.
6.2 Disorders
If the hand wheel of the test device cannot be
loosened while it is connected to a compressed gas
cylinder or compressor, check if connection is under
pressure. In this case close the cylinder valve or
compressor valve and release air from test device.
Leaks at the connection to the cylinder resp.
compressor could be due to a defect gasket. In this
case replace the gasket.
If the high pressure gauge or the detector tube
holder are defective, they must be replaced.
In case of other disorders the device should be
returned for repair to MSA AUER or any authorized
service station.
