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 minimise the risk of the
overpressure.
Set the desired pressure via the fine adjustment
valve (arrow).
Normally, the test is carried out when the
pressure falls because the gas density
instruments are generally specified and adjusted
in such a way.
To reduce the pressure, turn the fine adjustment
valve counterclockwise.
Further reduction of the pressure is possible by
means of the pressure relief valve.
To increase the pressure, turn the fine
adjustment valve clockwise.
Use the digital pressure gauge to read the set
pressure.
