Initial Setup and Basic Pressure Generation
The Product has a special low-volume calibration hose for faster pressure generation and
quick pressure stabilization. "Quick-fit" hose connectors and different adapters are
included. It is recommended that this hose is used to get the best results. After the fittings
are installed and the Product is connected to the UUT (unit under test), the Product is
ready for use.
To configure the Product for the appropriate application:
1. Set the pressure/vacuum selection knob to the necessary function (+ for pressure
and - for vacuum).
2. Close the vent knob.
3. Close the supply metering valve.
4. Push and hold and see the pressure rise (or vacuum generation) until you reach
the necessary pressure.
5. Release when the necessary pressure is reached.
Note
The motor speed starts slow while the pressure is low <15 psi (1 bar) for
better control at low pressures.
6. The fine pressure adjustment lets you set the correct pressure.
7. To decrease or bleed off all pressure, slowly turn the vent knob counter clockwise to
the open position. When the valve is slowly opened, there is a slow decrease of
pressure. Open the valve more to vent the pressure.
Pressure Measurement
To measure pressure:
1. Connect the Product with the correct adapter.
2. Select the pressure parameter for the display used.
3. The Product has an internal sensor and optional external sensors are available. Select
a sensor that is correct for the pressure range and accuracy.
Warning
To prevent injury, only assemble and operate high-pressure
systems if you know the correct safety procedures. High-
pressure liquids and gases are hazardous and the energy from
them can be released without warning.
For a better understanding with respect to overpressure and burst pressure, follow the
specifications and these operation instructions. See the “Specifications” section. The
Product display will show "OL" when an inappropriate pressure is applied. When "OL"
is shown on a pressure display, immediately decrease the pressure to prevent damage or
possible physical injury. "OL" is shown if the pressure exceeds the nominal range by
110 %. Push to zero the pressure sensor after it is vented to atmospheric pressure.
