Calibration with Load Cell Data (“Smart Calibration“)
If the scale to be calibrated is not legal for trade, it can be calibrated without weights. The easiest method is
the one using load cell data without calculation [by data].

of a load cell (not the overall nominal weight of the scale).
[Gravity]
Acceleration of gravity at the place of installation; default is the value for Hamburg, Germany, 9.81379 m/s².
[Hysteresis error]
When switching from [Not specified] to [Specified], values for [Correction A/B] must be filled in. The data is
given on the load cell certificate.
[Certified data], [LC sensitivity], [LC resistance]
With [all LC same], only 1 value for the sensitivity [LC sensitivity] and the output resistance [LC resistance]
must be filled in. With [each LC specific], individual values for each load cell are requested.
[Calc]
The mV/V value is calculated and after confirmation with [OK], the calculated mV/V value is stored in the
calibration data.
