Fault Finding - Baker Hughes Druck PV 211 Bedienungsanleitung

3.2 Operation with a High-Resolution Pressure Calibrator
Because the resolution is better, it is possible you will see more of the small pressure changes
identified in step 6 above.
Note: On very high resolutions such as 1 mbar or 0.1 inH
may result in noticeable pressure changes.

4. Fault Finding

1. If the system appears to lose pressure, repeat the above procedure. Make sure: there
is no damage to the seals, the adapters are tightened sufficiently, the pressure
release valve (1) is tightened sufficiently to seal.
2. Do not try to tighten the connections between the pump and the fine adjust
vernier (2) or between the pump and the quick-fit connectors (4). These are factory
set and changes can cause damage to the sealed joints.
3. During leak tests, small air movements (in or out) are possible around the pressure/
vacuum selector (3). This is normal.
4. If the PV 211 has not been used for a period of time, it can be difficult to operate on
the first stroke. It will become free after this.
5. For seal replacement refer to the service kit instructions.
If, for any reason, a fault occurs within the pump, it is recommended that the equipment be
returned to an appointed agent.
