User Configuration
All user parameters are embedded in a users
menu consisting of 5 separate menu selections,
each with its own sub-menu of choices. If your
scale is connected by RS-232 serial communi-
cation lines to other equipment, or you wish to
select the automatic power off period (battery
option only), you may have to modify some or all
of these parameters. To modify these parame-
ters
parameters, you must first enter the USER
MENU mode.
Once there, four of the front panel keys become
directional navigators to move around in the
menus, and one key is used to save or SET the
selections. Complete directions start below.
