Leakage test (LEAK)
In case the test device has to be checked whether it is connected pressure-tight, you
can start a leakage test with the LEAK button at each pressure step, upon reaching a
stabilized value. The pump is now switched off; the middle display value shows
whether a stable value is being held or whether the pressure value sinks. Pressing
the LEAK button again, you return to the CTRL operating mode.
Example
(see display photo):
- Lower left: time since pressing LEAK in s, here 89 s
- Lower middle: Pressure change in % since pressing
LEAK, here increase by approx. 1%
- Lower right: Absulute Pressure change, here by
+0,099 hPa
Leaving the operation mode CTRL
When pressing the MENU button, the Pneumator is first driven into the VENT mode
(venting) in order to reduce the internal pump pressure. By pressing the MENU
button again, the operation menu is shown. In the submenu “Modus” another mode
of operation can be selected.
