Eliwell ID 985 - User Manual

USER INTERFACE
The user has a display and four buttons
for controlling instrument status and pro-
gramming. The device can also be con-
nected to a remote display.
At start-up the instrument performs a
Lamp Test; the display and LEDs flash for a
few seconds to check that they are work-
ing correctly. The instrument has two main
menus: the Machine Status menu and the
Programming menu.
ACCESSING AND USING MENUS
The resources are arranged in a menu that
can be accessed by pressing and quickly
releasing the “set” button (Machine Status
menu) or holding down the “set” button
for more than 5 seconds (Programming
menu). To access the contents of each
folder indicated by the relevant label, just
press the “set” button once.
You can now scroll through the contents
of each folder, modify it or use its func-
tions.
If you do not use the keyboard for over 15
seconds (time-out) or if you press the
“fnc” button once, the last value shown on
the display is confirmed and you are taken
back to the previous screen mask.
REMOTE DISPLAY
This has a display with 3 digits + sign that
displays the parameter programming and
alarm display values on the controller it is
connected to during probe reading.
