3.1 USER INTERFACE
PPC3 is designed to offer a practical balance between simple, straight forward operation and
the availability of a wide variety of advanced functions with a high level of operator discretion.
The local operator interface is through a 2 x 20 display, a function/data keypad, a cursor
control pad and direct pressure control keys.
Remote communication is by RS232 (COM1) or IEEE-488. See Section 4 for specific
information on remote communication.
3.1.1 MAIN RUN SCREEN
The PPC3 MAIN RUN screen is its home display that is reached on power-up and from which
other functions and menus are accessed. It is the very top level of all menu structures.
The MAIN RUN screen is where the operator works with PPC3 to set and read pressures.
It provides complete information on the system’s current configuration and operating status.
Figure 3 and its legend table summarize the PPC3 MAIN RUN screen fields and their functions.
PPC3 has a screen saver function which causes the display to dim if no key is pressed for
10 minutes. Pressing a key restores full power to the display. The screen saver time can
be changed or screen saving can be completely suppressed (see Section 3.5.5.1).
