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 1
4 , 15 , 16 and 19 on
the keypad (see figure 21 in the general
appendix). The configuration screens
can be accessed by pressing key 1
3 .
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 1
0 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 1
0 and 11 on the
keypad.
The return to the primary message is
automatic after a 2 minute time delay or
by pressing key 1
8 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 1
0 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 1
8 (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.
