Display of messages
In addition to keypad operations, the
graphical display brings up a window
giving the overall device status. The
message displayed is then said to be
primary (see list in the paragraph
below). A primary message can be
used to access the measuring tables
using keys  14 ,  15 ,  16  and  19  on
the keypad (see figure 21 in the general
appendix). The configuration screens
can be accessed by pressing key  13 .
A flashing arrow appears at the end of
a primary message if there is a problem
or an alarm; secondary messages can
be accessed by pressing key  10  on
the keypad (see the list of secondary
messages). The presence of another
message is indicated by the arrows  
and     at the end of the secondary
message. They can be accessed by
pressing keys  10  and  11  on the
keypad.
The return to the primary message is
automatic after a 2 minute time delay or
by pressing key  18  on the keypad.
Control-panel display
General organisation
The display is structured around
primary and secondary messages,
measuring tables and setting screens.
As a rule, the message displayed on
the screen is always a primary one.
The secondary messages, if any, are
accessed by pressing keys  10  
 and
11  
 (see figure 19).
The presence of secondary messages
is indicated by the arrow     at the end
of the primary message. Return to the
primary messages is automatic if the
keypad is not used for 2 minutes, or
direct by pressing key  18  (see figure
19). The display screen lights up when
a key is pressed, and goes off if no key
is pressed for 5 minutes.
Note:
Most functions may be directly
accessed. For example, when voltage
measurements are currently displayed,
it is possible to directly access current
measurements by pressing the "A"
button.
