How to check magnet polarity?

Before installing the speed sensor or magnets in to the car, it's best to check polarity on the table. Here is some steps how to do it.

• Connect sensor to main unit
• Connect main unit to computer
• Activate calibration mode in Connector to see the real time values
• Move magnet (flat side) across the sensor and see if you see change in the input values
  • If input activates, then mark the side which is facing sensor with marker
  • If not activating, then turn magnet around and try again
