5.4.8 Calibration with Load Cell Data (smart calibration)
If the scale is not ‘legal for trade’, calibration without weights can be performed. The easiest method is the one
using load cell data without calculation [by data].
Weighingpoint/WP A/ Calibration
Max 3000 d 3000 kg
Scale interval 3000 d 1 kg
Deadload at 3.00 kg 0.001000
Max at 3000.00 kg 0.000000
Not calibrated
Sensitivity 833.33 4.000000
by load by mV/V by data Linear. CalcTest
Start by pressing [by data].

Nominal load 3000 kg
Gravity 9.81379 m/s²

[Number of load cells]

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.
