System Setup
The Model Mini-ICS is shipped ready to install and operate with complete factory configuration
already programmed and tested. The user may however wish to change the system configuration
to suit the application of the analyzer. Some setup parameters may be changed by the user via
the front panel keypad. All configuration parameters may be changed by the user via the Service
Port.
Important:
Before changing any of the Model Mini-ICS settings, refer to Appendix C
– Factory
Setup for reference. If the user has any questions before proceeding with changing analyzer
settings, please contact the Neutronics Service Department for assistance.
4.1.1 System Setup via Front Panel Keypad
The Front Panel User Setup menu may be accessed from the Mini-ICS front panel by pressing and
holding the “MODE” key for at least 6 seconds until the 7-segment alphanumeric display shows
“---" to indicate that the analyzer has accessed setup mode. Release the Mode key to activate
setup mode. Once in Setup mode, the user can access adjustable parameters sequentially by
continuing to press and release the “MODE” key to scroll through the Setup menu.
When you reach the mode that yo
u wish to change, use the “UP” and “DOWN” key to adjust the
displayed setting. The modes are numerically identified by the flashing number on the left side of
the display. The current setting is identified by the non-flashing number on the right side of the
display. The new settings are automatically saved when the user advances to the next mode by
p
ressing and releasing the “MODE” key. The user may exit the Setup menu at any time by
pressing simultaneously the “UP” and “DOWN” keys (Appendix D, Front Panel Hot-Key functions).
