Spirit System

I am setting up a heli with an RPM Sensor for the first time. I just want to make sure my setup will work. I am using a Spartan RC Governor RPM Sensor. On the Spirit RPM Sensor testing window the Sensor Signal is Active (1) without the magnet next to the sensor. When the magnet is next to the sensor, the Sensor Signal goes Inactive (0). This seems backwards. Will it work like this, or do I need to change something?

I tried an Align RPM Sensor with the red and black wires swapped as instructed, and got the same result, so I assume that this is a good thing.

Thats what mine does,its how it does it i think. Im sure i read somewhere before about same thing and there was no issue. But maybe wait for confirmation from zexx.
