Once the instrument to be tested/calibrated is connected to the test connector, the maximum test pressure can be set by means of the high-precision pressure regulator. The set pressure can be read on the monitor gauge. Two needle valves are used for fine
adjustment of the pressure. The test pressure is shown on the digital display. A third monitor gauge, connected in parallel to the digital gauge, is used as an "aid"for quick adjustment of the test pressure.
