Display/Function Selection Screen
The 'Display/Function Selection screen' is shown when the P is switched on and can always be
located by repeatedly pressing the 'Esc' (Escape) key. The 'Display/Function screen' allows the user to view
detected gas levels in a variety of formats or to adjust the instruments functions and parameters. The
symbols shown on this screen can be selected using the UP and DOWN keys. The highlighted symbol
appears as shown in the example below for the function menu.
Instrument Symbols Explained
A number of symbols are used to indicate various features when in the viewing screens. Please see an
explanation of each below.
Bump test
This symbol of a gas bottle can be set via the IonPC software to be displayed once a week when the
instrument is turned on. This is to remind the user to test the instrument responses accurately when it is
supplied with gas. See page 32 of the software section for more information.
Battery Status
The battery status indicator can be accessed by pressing and holding Enter on the graph and the large n
umber
screens.
Peak Hold
The numerical measurement to the right of this symbol indicates the highest gas concentration reached by
the instrument since being switched ON. This 'Peak' reading can be reset by pressing and holding the 'Enter'
key for 5 seconds.
