Calibration/Comparison Against An Analog Gauge - Baker Hughes Druck PV 211 Bedienungsanleitung

3. Operation
WARNING
cause damage to equipment. Because the internal pressure can get very
high during operation, make sure that all the connections are made
correctly.
DO NOT ignore the maximum operating pressure specified on the pump
label.
Before you connect a pressure component to the PV 211, make sure that it
is isolated from the pressure supply and release the internal pressure
slowly. DO NOT connect the pump to an external pressure source.

3.1 Calibration/Comparison against an Analog Gauge

1. Connect a reference instrument to the pressure port at the top of the pump (9).
2. Connect the instrument under test to the connection at the end of the flexible
hose (5).
Note: The maximum torque for the adaptors is 15 Nm (11 ft lb).
3. Set the fine adjust vernier (2) to the midpoint of its travel:
Turn it fully clockwise, then four to six turns counterclockwise.
4. Close the pressure release valve (1):
Turn it fully clockwise, and tighten to seal.
5. Operate the scissor handles (7) until the pressure is almost correct. To get the
maximum pressure output, squeeze the handles fully together on each stroke.
6. 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.
INFORMATION
adjust vernier (2) farther than the red line indicator on the thread. See item
11 in Figure #2.
Note: Initially, small pressure changes can occur (thermodynamic effects, the
seals settle, the hoses expand). The pressure will stabilize after a short time.
7. You can also decrease the pressure by careful operation of the pressure release
valve (1).
8. 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.
