Theoretical Calibration For Other Units Of Measure
Set in the parameter the F.SCALE value divided by the conversion coefficient from kg to the new unit of measure.
Example: The 4 load cells of 1000 kg are placed under a scale for olive oil, which has a specific gravity of 0.916 kg / l.
Setting the F.SCALE = (4x1000) / 0916 = 4367, the system works in liters of olive oil. If you set the unit to litres, the system
will display and print the symbol ‘l’ instead of ‘kg’. See Section 2.1.6 on page 16.
Weight (Span) Calibration For Other Units Of Measure
Load a known quantity of product litres on the scale (use as high a percentage of the maximum quantity to be
weighed as possible) and enter in the parameter UEIGHt, the product loaded value in litres. If you set the units to
litres, the system will display and print the symbol ‘l’ instead of ‘kg’. See Section 2.1.6 on page 16.
2.2 Filter On The Weight
The filtering selection is used to eliminate environment noise, and is typically a compromise between
responsiveness and stability. The lower the number, the more responsive the display will be to weight changes.
The filter is used to stabilize a weight as long as the variations are smaller than the corresponding “Response
Time”. The filter setting is dependent on the type of application and the required update rate.
Setting the parameter allows a stable weight display to be obtained. To increase the effect (weight more stable),
increase the value.
1. Press and hold , then press to enter set-up menu, CALIb will be displayed.
2. Press or until FILtEr is displayed, press . The currently programmed filter value is displayed.
3. Press or until desired filter value is displayed, press .
4. The current weight is displayed (all LED’s flashing) and the displayed stability can be experimentally
verified. Press .
5. If stability is not satisfactory, press , this returns indicator to FILtEr option and the filter may be
modified again until an optimum result is achieved.
6. Press to exit set-up menu.
The filter enables to stabilize a weight as long as its variations are smaller than the corresponding “Response
Time”. It is necessary to set this filter according to the type of application and to the full scale value set.
