2.
The transducer's zero point (tare) is calibrated with the minimum load on
the sensor and mode = 6 (configuration of cutoff frequency for AIx, bits
11-13). This defines the initial value for the scale.
3.
The transducer's full-scale calibration is carried out with the maximum
load on the sensor and mode = 7 (configuration of cutoff frequency for
AIx, bits 11-13). This defines the final value for the scale. The final value
for the scale can only be calibrated to a value between 50% and 100%
of the positive measuring range.

1) The measuring ranges are sized for load cell overstretching of 50%
2) Typical values with active sinc filter and measuring range of 2 mV/V
3) A system calibration with the sensor, in which the minimum and maximum values are calibrated, is re-
quired in order for the measuring accuracy value to be met. The minimum value must be calibrated
first, followed by the maximum value. The maximum value can only be calibrated to a value between
50% and 100% of the positive measuring range.
