Symbol of display Meaning Explanation
ZERO ZERO Indicates if ZERO-function is
active.
5.4.4 Measurement Mode with bargraph
The display shows the leak rate in big digital figures, see Fig. 14. The unit
of the leak rate is shown, too. Underneath the leak rate the inlet pressure
is displayed in smaller digits. The units of leak rate and pressure can be
defined in the menu (See Chapter 6.4.4).
Below this the same leak rate is shown graphically as a bar. The scale of
this bar, i.e. the number of decades included in this bar can be defined in
the menu (Please refer to Chapter 6.2.2). The programmed trigger levels
(Please refer to Chapters 6.4.1 and 6.4.2) are indicated at the bar by short
vertical lines: a straight line for trigger 1 and a dotted line for trigger 2.
5.4.5 Measurement Mode with trend information
In trend mode the leak rates are displayed over time Fig. 15. In addition
the actual leak rate and inlet pressure also are displayed digitally. The time
axis can be defined in the menu (Please refer to Chapter 6.2.3 Time axis).
The intensity axis (y-axis) is defined the same way as the bargraph (Please
refer to Chapter 6.2.1 Scale linear/logarithmic).
