THEORETICAL CALIBRATION
This function allows the load cell rated values to be set.
To perform the theoretical calibration set the following parameters in sequence:
-
(Default:
)
:
The
system full scale
is given by one cell capacity multiplied by the
number of cells used. Example: 4 cells of 1000 kg
FULL SCALE = 1000 x 4 = 4000.
The instrument is supplied with a theoretical full scale value
corresponding to 10000. To
restore factory values, set 0 as full scale.
-
(Default: 2.00000 mV/V):
Sensitivity
is a load cell rated parameter expressed in mV/V.
Set the average sensitivity value indicated on the load cells. It’s possible to set a value between
0.50000 and 7.00000 mV/V. Example of 4-cell system with sensitivity: 2.00100, 2.00150,
2.00200, 2.00250; enter 2.00175, calculated as (2.00100 + 2.00150 + 2.00200 + 2.00250) / 4.
-
:
The
division
(resolution) is the minimum weight increment value which can be
displayed. It is automatically calculated by the system according to the performed calibration, so
that it is equal to 1/10000 of full scale. It can be changed and be variable between 0.0001 and
100 with x1 x2 x5 x10 increments.
-
By modifying the theoretical full scale, the sensitivity or divisions, the real calibration is
cancelled and the theoretical calibration only is considered valid.
-
If the theoretical full scale and the recalculated full scale in real calibration (see section
REAL CALIBRATION (WITH SAMPLE WEIGHTS)
) are equal, this means that the
calibration currently in use is theoretical; if they are different, the calibration in use is the
real calibration based on sample weights.
-
By modifying the theoretical full scale, the sensitivity or divisions, the system’s parameters
containing a weight value will be set to default values (setpoint, hysteresis, etc.).
