How to Modify Measurement Information

Introduction
The configuration screen offers the following measurement information.
Designation
Description
Unit
gives the choice for the weight measurement unit:
  • g: gram
  • kg: kilogram
  • t: tonne (metric)
  • lb: pound (lb =  453 g)
  • oz: ounce (oz =  28.35 g)
  • without: any unit
Max Range (MR)
This is the maximum weight that it is possible to weigh with the instrument and without including the weight of the empty load receiver (in the legal format).
Scale Division
The value of the scale division is in the form of 1, 2 or 5 multiplied by 10n (n being a positive or negative integer or zero with its absolute value ≤ 3).
Example: for a scale division of 0.002 (if the unit chosen is the kg), the measurement increases by 2 g at a time.
Overload Threshold
The threshold is the value of the weight above which the display panel no longer indicates the weight (the overload is then indicated with a > line on the display panel).
It may take the values:
  • +9 scale divisions
  • +2 % of the maximum range
  • +5 % of the maximum range
Example: the maximum range has been established at 150 kg, the scale division at 10 g, according to the choice of the user, the operating limit will be for:
  • 9 e: Max range + 9 scale divisions i.e. 150.09 kg
  • +2 %MR: 102 % of Max range i.e. 153 kg
  • +5 %MR: 105 % Max range i.e. 157.5 kg
Note: The under-load threshold cannot be parameterized: it defines the permissible limit of the indication below zero. It is -2 % of the maximum range (the under-load is then indicated with a < line on the display panel).
NOTE: In an industrial context, because of the environment of the weighing installation, choosing a resolution of more than 3000 points assumes that there are rigorous steps to perform before installation.
At the level of the programming screen, it will not be possible to input a resolution greater than 50 000 points. In other words the following disparity should be observed: Maximum Range (MR) ≤ 50000 x Scale division.
Procedure
The following table shows the procedure for defining the metrological information.
Step
Action
1
Access the weighing module configuration screen.
2
Select the parameter values Unit, Scale division or Threshold overload using the drop-down lists offered and enter the Maximum Range value.
3
Confirm the modification with the command Edit → Validate.
