Operating Range +/-5 VDC
In the +/- 5 VDC operating range, if you use the Advantys configuration software to
calibrate an offset of 64 at 0 VDC and a max count of 32 576 at +5 VDC, the system
could be represented as follows:
Here are some voltage representations after calibration with offset and max count:

0VDC 64 0
+5 VDC 32 576 +32 000
* For the STB AVI 0300 module, the calibration of the negative value is determined by
extending the linear equation determined by the offset at 0 VDC and the max count at
+5 VDC.
