Operation
Default Display : Status Indicator
3.2.3 Status
Indicator
The status indicator indicates the
Model 430 Programmer operating
status. It is always visible (except
during a quench condition) and is
displayed just to the right of the
field / current display (see Figure
3-1). The status indicator may be
one of six symbols indicating one
of the seven states shown in Table
If the ramping mode character is
blank, then a quench condition
exists and the red MAGNET
QUENCH indicator in the status
section of the front panel will be
illuminated. See section 3.12 on page 79 for a detailed discussion of the
meaning of the ramping modes (Paused, Ramping Up, Ramping Down and
Holding).
3.2.4 Main
Display
The default main display (the rightmost portion of the display – see Figure
3-1) shows either a voltmeter indicating magnet voltage or ramp mode and
persistent switch heater state. Ramp mode is displayed on the top line of
the main display; it will be one of eight states, as shown in Table 3-6 on
page 80. Persistent switch heater state is displayed on the bottom line of
the main display. If the Model 430 Programmer has been setup for use
with a persistent switch, it will indicate either ON or OFF for the
persistent switch heater state; otherwise, it will display “No PSwitch
Installed.”
3.3
Entering Numeric Values
A consistent method of entering values is used within menus requiring
numeric entries. Once a menu is selected, the user may start an entry by
pressing a digit (
0
through
9
), the decimal key (
.
), or the sign key (
+/-
).

The display will begin a new entry and display a cursor (
_
) as a prompt for
the next digit or decimal entry. Also, once entry is initiated, the display
will show an asterisk (
*
) indicating that numeric entry is
active
.
Alternately, the
ENTER
key may be pressed before any of the numeric
keypad keys; the display will begin a new entry and display a cursor (
_
) as
1. Certain menu items requiring numeric data can also be entered using the fine
adjust knob (see section 3.4 on page 31).
