– FAD-40 Setup Parameters
For entering the parameter values enter the setup tab, adjust the parameter settings and then write this data to
the A/D Converter. After changing parameter settings the instrument always requires a re-calibration.
4.3.1. Scale Parameters
In the setup menu the scale parameters of FAD-40 can be viewed, changed or saved to the instrument. These
parameter settings are:
Increased External Resolution
For service purposes this parameter enables the 10 times higher resolution of the weight value than the defined
interval in weighing and force mode. Increased resolution must be disabled for use in normal operation (Not
available in Count Mode). Default setting: ‘Disable’.
Digital Filter
Environmental noise like bounding forces, air flow, vibration, motor control instruments etc. may disturb the load
cell signal. The selection of proper filter settings determines how quickly the system will react to the load cell
signal.**Load cell signal digital filtering is done according to this parameter settings. The settings can be
changed from 0 (fastest settling) to 9 (slowest settling). Default setting: ‘7’.
