LSB Default Comment Example
CAL IA 08
16384 is
the default
and is a
gain of 1.
32767 is
max giving
a gain of
2.
+13873
Gain constant for IA
input.
If current on channel A is low by 1%
scale the nominal number, 16384 by
1/(1-0.01). Number to be entered would
be 16549:
]08=+16549<CR>
If current on channel A is high by 1%
scale the nominal number, 16384 by
1/(1+0.01). Number to be entered would
be 16222:
]08=+16222<CR>
