6. Commissioning, operation

Switch on the calibration system.

The measurement setup shall be now as in the gure.

Actuate the pump handles several times until the

desired pressure is slightly exceeded.

To achieve the maximum pumping capacity, the spring above the knurled

nut must be relaxed.

For test items with low measuring ranges, the stroke path can be reduced

by turning the knurled nut. This will reduce the pressure increase per

stroke and minimize the risk of the overpressure.

Set the desirede pressure via the ne-adjustment

valve (arrow).

Normally, the test is carried out when the pressure falls

because the gas density measuring instruments are

generally specied and adjusted in such a way.

To reduce the pressure, turn the ne-adjustment valve

counterclockwise.

Further reduction of the pressure is possible by means

of the pressure relief valve.

To increase the pressure, turn the ne-adjustment

valve clockwise.

Use the digital pressure gauge to read the set pressure.
