USING THE PUMP
Preparation
Before applying pressure/vacuum, ensure that the pressure/vacuum selector is ac-
cording to your calibration needs. If not, check that the release valve is open, and
then use a small screw driver to change the setting of the pressure/vacuum selector.
IMPORTANT
Never change the pressure/vacuum selector's setting when there is
pressure or vacuum in the pump/system.
Please read all the warnings found on page 9.
Before doing the connections, check that the pressure hose is intact and the o-rings
in it are in place. Use only the pressure measurement T-hose delivered with the
pump. Also check that the pump is in working condition.
Use the pressure measurement T-hose to connect the Device Under Test (DUT) and
the reference (a calibrator with internal pressure modules or an external pressure
module communicating with a calibrator) to the pump. For help on connections, refer
to the adjacent connection diagram. Use hand tightening for the connections. Ensure
that the measurement range of the connected reference is appropriate.
Note.
It is not recommended to use the plugged connection on top of PGC. Further
information in warnings, presented on page 9.
Normally: Check that the thumb nut of the stroke length setting is approx. 1 centime-
ters from the lowermost position. If you for some reason need to reduce the volume
per stroke, raise the thumb nut to squeeze the spring. This can also be done during
the calibration run.
Turn the release valve clockwise to close it.
Continue either from chapter Operation (Pressure) on page 4 or Operation (Vac-
uum) on page 5.
