Note: The Range setting is fixed in the -E6782 version.
The output signal of the Hall cell is amplified in the pre-amplifier.
Eight ranges can be selected by setting the PRE bits.
The output voltage range of 3 ... 97% of
Therefore the product of sensitivity and full scale range is always 4.7 V.
Note: Sensitivity x Full Scale range = 4.7 V

In the bipolar mode, the full scale range is composed of a positive and a negative part
with the half value each. (e.g. 142.4 mT ... 204.4 mT in range 0).
Note: The range should be set before the calibration of the gain.
