# Analog

* Gain sets the scale in uS/Volt. A 0-3.3V signal with a max channel value of 1024us works out to 1024/3.3=310 (Which is the GUI default)
* Offset allows you to tweak the zero point for your signal, if your pot doesn't go all the way to zero for instance. As of V2.1x you can set negative values here
* Inverting an analog channel isn't as obvious but it can be done in the GUI instead of re-wiring. Set the gain to negative (-310.3) and set offset to 1024
