Option selections using the display switch
The DISPLAY switch is used in conjunction with the three green
LED displays (the Units portion of the main display, the parameter
annunciator, and the Control Status display). It has a central rest
position, OPER(ate), and two momentary positions, NEXT and
SELECT. In general, NEXT allows you to get into Option Selection
mode, scroll through various portions of the menu, and scroll
through digits and characters to set values. SELECT allows you to
select which area to access and to set values and characters.
A simplified
explanation of
the option
selection
system
The DISPLAY switch provides you with several main menus. In
sequence, these are:
UNITS on the top display
UNITS on the bottom display
OUTPUTS on the top display
OUTPUTS on the bottom display
Menu navigation.
It’s easier than it might first appear to move about and select
options. Follow the three-step process below.
1. Press NEXT until you see one of the above main menus that
you want. When you get to the one you wish to see, press
Select. This action puts you IN that main menu, and you can
proceed to scroll through it until you see the submenu you
want.
2. When you see it, press SELECT. You are now IN that submenu.
By pressing NEXT, you can scroll through it and find the
parameter you wish to select.
3. When you find the one you want, save it by pressing SELECT.
Indications on the front panel will guide you. It may sound
complicated, but once you have done it a few times, it will
seem very logical.
It is suggested that you now proceed to try it intuitively. The indi-
cators will help you, and you may not need to use the manual. If
you do run into trouble, consult the following sections.
