2.6 Scale Base Setup
In this section, you will enter the menu for the first time. Do not worry if you are unfamiliar with the function of the
buttons on the panel, the display provides the necessary coaching as you go along. Before the Indicator can be used,
the parameters for the scale base being used with the Indicator must be set first in order to calibrate and perform any
functions.
The indicator itself has three basic menus; each is selected by front panel buttons marked Mode, Units and Setup.
Mode Button
The Mode button, when pressed, permits the selection of 5 weighing modes which are: weigh, percent, count, animal
weighing and checkweigh. These modes are controlled by an ON or OFF selection made in the Setup menu under the
submenu Mode as displayed.
Units Button
The Units button, when pressed, allows the Indicator to display values in a selected measuring unit of either grams,
kilograms, pounds, custom, parts counting or percent.
Setup Button
The Setup button, when pressed, allows entry into 14 submenus which allows you to set the Indicator for specific
operating parameters. Each of the 14 submenus contain settings which are user selectable . The table which follows
the scale base setup illustrates the various submenus and the functions which are selectable. The items shown on
the menu, which are bolded, are the factory default settings. In other words, if you did not enter the Setup menu, the
Indicator would function in the basic manner shown by the various settings which are bolded. The setup submenus
shown are arranged in the order as displayed in the Indicator .
Scale Menu
The Scale menu is the first menu presented when the Setup button is pressed. This menu allows you to set the proper
parameters of the scale base such as zero setting, calibration unit, graduations, full scale capacity and to lock all
settings. The definitions are as follows:
• Zero -The percentage of capacity which the user is allowed to zero the scale base and can be set
to 2%,18% or 100%. If the weight on the scale base is greater than the selected percentage, the >0< button will not respond.
• Cal Unit - kg, lb are used to set the scale base capacity and calibrate the unit. If the display units are
the same as the Cal unit, then weight displayed on the Indicator will be a multiple of the
Grad setting.
• Grad -The display increment of the scale base can be set to .0005, .001, .005, .01, .02, .05, .1,
.2, .5, 1, 2, 5, 10, 20, 50, 100. The weight displayed on the scale will always be a m ultiple
of the Grad (graduation).
• Full Sc -This represents full scale base capacity and the user may enter 7 digits. Number may be
entered using the arrow or numeric buttons. This number must be betw een 1 and 199999.
