To get into PPR (Pulses Per Revolution) calibration, you will press and hold the button down while power the gauge on (or menu button if you have 2 on the front)

You will determine your PPR based on the chart below. While in calibration, pressing and releasing the button will cycle through the options. 

After 5 seconds, the gauge will exit calibration and save the PPR the pointer is currently on, return to 0 then show the RPM reading.

If you have a dual speedometer + tachometer, then you will set the calibration on the screen display instead, holding button down while powering on, press and release button to cycle through menu options, hold the button for 3-4 seconds to select "Set pulses per rev" menu option, then press and release to increase PPR. The PPR will save after 5 seconds of inactivity.
