Each 2 to 8 V input signal is scaled to weighing
reading using the Lo, Hi 1, and Hi 2 settings in the
configuration menu. Lo is almost always 0, and Hi
1 and Hi 2 correspond to the full scale weighs of
the input channels. The unit of the scaling can be
freely selected (kg, ton, lbs...) and there is no need
for the display to know it. Then, negative readings
are prevented (limited to 0), before summing up
the readings. A tare value is subtracted. A new tare
value can be stored using an external switch.
The 3rd order lowpass filter can be used to
attenuate fluctuations and disturbances. The filter
is bypassed a couple of seconds after power-up.
