4. Design and function
The front screen of the display, behind the membrane, is made from
glass. If there is any possibility of the window breaking during operation
(including damage to the front membrane), all personnel in the vicinity of
the instrument must wear eye protection before and during its use.
4.5.1 On/Off button
Button to turn the instrument on and off.
4.5.2 Menu button
With this button the SETUP menu can be accessed, and there the
settings for each operating mode can be made. When the CTRL mode
is used, you will find that the device is left in VENT mode on leaving the
SETUP menu.
The SETUP menu items are made up of six submenu items. For a detailed description of
these items, see chapter 6.5 „SETUP settings (SETUP)“.
4.5.3 LEAK button
With the LEAK button, a device connected to the controller can be
tested for leaks. (This feature is only available in CONTROL mode.)
4.5.4 ZERO button
Button for manually correcting the zero point of the integrated sensor.
External influences such as temperature, pressure, mounting position or
surroundings, can alter the zero point of the instrument, i.e. the display
when the pressure ports are open. During zero adjustment, the device
automatically detects these changes and corrects them in the current
pressure display. The zero point adjustment requires a change of the
internal valves, which is not possible without loss of pressure.
(If this should interfere with the application, the automatic zero point
adjustment can be switched off.)
