Turn it fully clockwise, and tighten to seal.
5. To set a maximum output pressure, use a screwdriver to adjust the pressure relief
valve (8):
Turn it clockwise to increase the pressure or counterclockwise to decrease the
pressure.
6. Operate the pump handle (7) until the pressure is almost correct.
7. To adjust the pressure to the correct value, turn the fine adjust vernier (2) clockwise to
increase the pressure or counterclockwise to decrease the pressure.
Note:
Initially, small pressure changes can occur (thermodynamic effects, the seals
settle, the hoses expand). The pressure will stabilize after a short time.
8. You can also decrease the pressure by careful operation of the pressure release
valve (1).
9. To get a vacuum, set the pressure/vacuum selector (3) to the vacuum position (as
indicated on the pump label) then use the same procedure as above.
Note:
Before you change the mode, release the pressure.
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 7 above.
Note:
On very high resolutions such as 1 mbar or 0.1 inH
2
O, small movement of the hose
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 other connections on the pump. 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 210 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.
INFORMATION
To prevent damage, when the top of the pump body
comes into view, DO NOT use force to turn the fine adjust vernier (2) farther
out.
