Calculate dead load
Voltage equivalent [mV/V]= dead load × load cell sensitivity C

Normally, calculation of the dead load (scale without load or empty vessel) is
not necessary.
Subsequent dead load correction can be used for later re-determination of
the dead load, when the scale or vessel is empty.
Example:
