3.1 USER INTERFACE
PPCH 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 information on remote
communication.
3.1.1 MAIN RUN SCREEN
The PPCH 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 PPCH to set and read pressures.
It provides complete information on the system’s current configuration and operating status.
Table 5 summarizes the PPCH MAIN RUN screen fields and their functions.
PPCH 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).
