3.2.9 Measurement Mode with Bargraph
The display shows the leak rate in big digital figures, see Fig. 10 . 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
3.8.4 ).
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
3.6.4 ). The programmed trigger levels (Please refer to Chapters
3.8.1 and 3.8.2 ) are indicated at the bar by short vertical lines: a straight line for
trigger 1 and a dotted line for trigger 2.
3.2.10 Measurement Mode with Trend Information
In trend mode the leak rates are displayed over time Fig.11. 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
3.6.5 ). The intensity axis (y-axis) is
defined the same way as the bargraph (Please refer to Chapter 3.6.4 ).
3.3 First Operation Check
The steps for an initial operation are described here. It is explained how to switch
on the PHOENIX L300i, how to measure and how to carry out an internal calibra-
tion.
If anything unexpected happens during the initial operation or the leak detector
acts in a strange way the PHOENIX L300i can be switched off by the mains switch
at any time.
FINE Vacuum area Depending on the inlet pressure
the PHOENIX L300i may be in
GROSS, PRECISION (PHO-
ENIX L300i DRY only) or FINE
mode, which is indicated here
(Chapter
3.10.1 )
ZERO ZERO Indicates if ZERO-function is
active.
