Configuration
6.1.
General Setup Information
Configuration and calibration can be performed entirely from the front panel, using the digital setup
facility. When
Full Setup
is used, all menu items are accessible and care must be taken to ensure
no accidental changes are made to calibration and trade settings. In addition, there is also
Safe
Setup
that provides restricted access
.
This setup method ensures that only settings that are not
calibration or trade sensitive can be changed.
Full and Safe Setup can be passcode protected to prevent unauthorised or accidental tampering. If
the scale has been passcode protected, the setup menus cannot be accessed until the correct code
has been entered.

Basic Weighing Terminology
The following terms are used throughout the setup procedure. Knowledge of these basic weighing
terms is beneficial in setting up and calibrating the instrument.
Note:
Descriptions of these and other terms used in this manual are listed in the Glossary Terms
page 59.
Term
Definition
Units
Units of measurement (kilograms, tonnes, pounds, etc.).
Full Scale
Total change in weight between zero gross load and full capacity gross
load.
Resolution or Count-by
Smallest change in weight units that the display can show.
Total Number of
Graduations
Maximum number of display steps between zero gross load and full
capacity gross load. It is equal to full scale divided by the count-by.
Division
A single graduation.
Example
This example provides a check to ensure the capability of an indicator to read a stable weight
on extremely small divisions compared to the load cell capacities.
The check is to find out what the microvolt per division is and then compare this to the
manufacturer's specification. If the manufacturer's specification is smaller than the calculated
value, the unit is within the requirements of operation.
Note:
The capability of an indicator may be different than the trade approval limit of the
micro-Volt per division.
A 10,000kg 2.0mV/V load cell is used in an application requiring a 5000kg full scale, with
weight displayed in 5kg increments.
The values are:
Units = kg
Full Scale = 5000
Count-by = 5
Calculating the total
number of
graduations:
Signal voltages can be calculated as follows:
