5.6 _8113_Gain_Select
Ø
Description
This function is used to set the A/D gain by means of software. The initial
value of gain is '
x1
' which is set by the ACL-8113A hardware. The
relationships between gain and input voltage ranges are specified by
following tables:
When input voltage range is set +10V(JP1) and Bipolar mode(JP2), the
relationship between gain and input voltage range is listed in the following
table.
