- -10 to 10 V
The --10- to 10-V range corresponds to the hexadecimal values F448 to 0BB8
(--3000 to 3000). The entire data range is F31C to 0CE4 (--3300 to 3300). A
negative voltage is expressed as a two's complement (16 bits). If the line is
disconnected, the data will be the same as an input of 0 V (0000 Hex).

--11 V --10 V
0 to 10 V
The 0- to 10-V range corresponds to the hexadecimal values 0000 to 1770 (0 to
6000). The entire data range is FED4 to 189C (--300 to 6300). A negative voltage
is expressed as a two's complement (16 bits). If the line is disconnected, the data
will be the same as an input of 0 V (0000 Hex).

The 0- to 5-V range corresponds to the hexadecimal values 0000 to 1770 (0 to
6000). The entire data range is FED4 to 189C (--300 to 6300). A negative voltage
is expressed as a two's complement (16 bits). If the line is disconnected, the data
will be the same as an input of 0 V (0000 Hex).
