To set the proportioning valve, it is necessary to simulate the actual test
conditions; the component being tested must be connected to the TEST output
as in the test; if the pneumatic connections or the type of component being
tested are changed, the proportioning valve must be reprogrammed.
If no test component is connected to the
can be set without opening the output
valves, i.e. without air outside the TEST
If a sample of the tested components is
pressure adjustment can be set by open-
ing the output valves, then with the air

Example:
actual test conditions:
: set the parameter
PR or
regulated pressure value;
PV%: position % of the proportioning valve;
: the output pressure can be adjusted manually by pressing the +/-% keys;
AUTO: pressing the button, the proportioning valve is automatically piloted to obtain
the programmed output pressure;
: the output valves are closed, press the key to open the valves and adjust
the test pressure on the TEST output;
: the output valves are open, press the key to close the valves and adjust the
internal pressure.
When the pressure reading corresponds to the programmed value, press the key
to exit the menu page.
The inlet air pressure supply must be at constant pressure in order to
-
ply changes or if the programmed pressure P0 or PR is changed, the starting
position of the proportioning valve must be reprogrammed.
this method generally allows faster testing, but the operator must al-
ways manually set the starting position in the test table when programming
the P0/PR test pressures.
