Presentation, index 0x80n0:02
The measured value output is set in factory to two's complement representation (signed integer).
Index 0x80n0:02 offers the possibility to change the method of representation of the measured value.
Signed integer representation
The negative output value is represented in two’s complement (negated + 1).
Maximum representation range for 16 bits = -32768dec to +32767dec

Overview of further representations
Unsigned integer representation
The output value is represented with 15-bit resolution without sign, therefore polarity detection is no longer possible.
Maximum representation range for 16 bits = 0 to +32767dec
Absolute value with MSB as sign - representation
The output value is displayed in magnitude-sign format: MSB=1 (highest bit) in the case of negative values.
Maximum representation range for 16 bits = -32767dec to +32767dec
