CONFIGURATION
OVERVIEW
The indicator contains two main configuration menus:
•
The Setup (“F”) menu, which configures the indicator to your weigh platform

options
The Setup and User menus consist of several menu selections, each with its own sub-menu of selections
or programming procedures. To configure the indicator you must first enter the appropriate menu mode.
Once there, four of the front panel keys become directional navigators to move around in the menus,
