6. Commissioning, operation
6.5.1 To apply pressure
For pressures up to 140 bar (2,000 lb/in²)
1. Close valve B (valve A remaining open).
2. Wind spindle pump handle clockwise. This will generate pressure up to approxi-
mately 140 bar or 2,000 lb/in², as handle is wound in. When handle becomes sti to
rotate this will indicate that the pressure limit for this range has been reached.
For pressures above 140 bar (2,000 lb/in²)
1. Close Valve A and open valve B.
2. Continue to wind spindle pump handle clockwise. This will generate pressure up to
approximately 1,200 bar or 16,000 lb/in².
6.5.2 During calibration
Increase the pressure via the spindle pump in the clockwise direction, or use the ne
adjustment to approach the individual calibration points.
The display of the pressure measuring instrument being tested can be compared with
the reference measuring instrument at the individual calibration points.
If there are still small air particles within the system, the generated test
pressure will initially drop and must be readjusted accordingly.
With higher pressures, a longer waiting time than with lower pressures
should be expected until the steady-state condition has been reached.
6.6 Completion
1. After the test is nished wind spindle pump handle anti-clockwise to lower pressure.
2. Gently open valve A or B to release residual pressure.
3. Ensure that both valves A and B are fully open.
4. Remove device under test.
The system is now ready for another test and any residual pressure is relieved.
