3.10 Numerical Calibration
If there is no reference weight value, it is possible to make a theoretical calibration
using capacity and sensibility values (mV/V) of the load cells used.
For a calibration of maximum precision you always have to use the calibration with
masses.
Within the numerical calibration level, parameters showed in Figure 3.10.1 can be
found.

Figure 3.10.1 Numerical Calibration
3.10.1 LCAP (lcap)
Nominal capacity (Emax) of one of the load cells from the scale. It is expressed in the
same decimal point used in MAX and DIV (see scale definition 3.2.3, 3.2.4 y 3.2.5).
3.10.2 LNUM (lno)
Number of load receiver supports. All supports must be counted, both those which
rest on load cells and those which do not.
3.10.3 L Sn (lsn)
Load cells nominal sensibility in mV/V (if values are not the same, calculate the
average).
3.10.4 ZERO (0ero)
- Automatic zero adjustment: To automatically adjust the zero value make sure there
is not any weight on it and press the enter key. The indicator will show the present coefficient
value. On pressing enter again the message *CALIB* will be shown while the indicator
assesses the present value. Once accepted it will be stored. It is recommended to keep this
coefficient value or print it by means of printing the parameters.
- Manual zero adjustment: to manually introduce the zero value the Arrow Down key
(
) has to be pressed. Then we select the corresponding digit with the Arrow Left and Arrow
Right keys (
). The selected digit value is modified with Arrow Up and Arrow Down keys
