Chapter Four: System Setup
Overview
The 651 pressure controller is configured entirely through menu selection via display lists that
appear on the front panel. It is not necessary to open the unit to set any switches. Valve
connection and calibration, sensor range and pressure units, etc. are selected by scrolling through
the display lists and making adjustments using the controls on the front panel. At initial power
up the display screen, listing the current software/firmware version, appears for about five
seconds.
The system then defaults to its
pressure and position
display and is ready for valve connection
and setup (or normal operation once the system has been configured).
