5.2.2 DR3 - Characteristic value range
Depending on the characteristic value of the connected load cells, the value
1 mV/V, 2 mV/V or 4 mV/V must be selected. Since the SIWAREX FTA supplies
the load cells with approximately 10 V, the measuring input is redefined according
to the expected measurement voltage (max. 10 mV, max. 20 mV or max. 40 mV).
If the characteristic value of the connected load cells is at e.g. 2.85 mV/V then the
next higher characteristic value must be set normally, i.e. 4 mV/V.
5.2.3 DR3 – Filter sequence of the signal filter
Changing the filter sequence can be an advantage in some cases. Normally,
the signal is first filtered by the average value filter.
