3.3
Manual Operation
is designed to offer the optimum balance between simple, intuitive operation and
the availability of a wide variety of functions with a high level of operator discretion. The local
operator interface is through the front panel’s 2 x 20 character alpha-numeric display and a
4 x 4 multi-function keypad. Remote operation by RS232 or IEEE-488 interface is also
available (see Section 4).
3.3.1
Keypad Layout and Protocol
has a 4 x 4 keypad for local operator access to direct functions, function menus
and for data entry.
The Editing and Execution keys
are for
execution, suspending execution, backing up in
menus and editing entries.
The Menu/Data keys
provide access to function
menus from the MAIN run screen. The menu
name is on the bottom half of the key. The SETUP
menu is for more frequently used functions. The
SPECIAL menu is for less frequently used and
internal functions. These keys enter numerical
values when editing.
The Function/Data keys
allow very commonly
used functions to be accessed directly from the
MAIN run screen by a single keystroke. The name of
the function is on the bottom half of the key (see
Section 3.3.2). These keys enter numerical values
when editing.
