12 Installing display unit / weighing bridge

Installation / configuration of the weighing system must be carried out by a well
acquainted specialist with the workings of weighing balances.

12.2 Weighing system design

The display unit is suitable for connection to any analogue platform in compliance
with the required specifications.
The following data must be established before selecting a weighing cell:
•
Weighing balance capacity
This usually corresponds to the heaviest load to be weighed.
•
Preload
This corresponds to the total weight of all parts that are to be placed on the
weighing cell such as upper part of platform, weighing pan etc.
•
Total zero setting range
This is composed of the start-up zero setting range (± 2%) and the zero
setting range available to the user via the ZERO-key (2%). The total zero
setting range equals therefore 4 % of the scale's capacity.
The addition of weighing scales capacity, preload and the total zero setting
range give the required capacity for the weighing cell.
To avoid overloading of the weighing cell, include an additional safety
margin.
