Speedhut Custom Gauges's video: Speedhut Tech Video 2 - Old Version Programmable Speedometer Calibration

IMPORTANT: These calibration instructions only apply to Programmable Speedometers shipped before 20 FEB 2015! In this Speedhut Tech Video we demonstrate how to Calibrate the 3-3/8", 4", and 4-1/2" Programmable Speedometer (NON-GPS). http://www.speedhut.com/gauges/ ATTENTION: Speed Sensor is sold separately. The drill was used for transmission simulation only. We do not recommend calibrating your Speedometer with a drill. Note: If your speedometer has a jack button then plug it into back of the speedometer. 1. With speedometer powered up press and hold the button for 10-12 seconds. Note: Keep holding the button past the Peak Recall if your gauge has that option. 2. Press and release button until the selection box is around the PPM icon (PPK for km/h models). The icon looks like a straight road. 3. Press and hold the button for 2-3 seconds to access PPM(PPK for km/h models) Calibration Mode. 4. LCD will prompt you to press button to start calibration. Note: Starting Calibration can be done while driving or while parked. 5a. Drive to mile marker and then press and release button to start calibration. 5b. Drive 2 miles (4 kilometers) from the mile marker and promptly press and release the button to complete the calibration. 6. Calibration is completed. The Speedometer will exit Calibration Mode automatically and begin reading MPH(KM/H) and mileage. The Speedometer is designed to work with any wave/pulse form from 1 volt - 100 volts. Pulses per mile from 500 - 250,000. If your speedometer is not accurately showing MPH, double check your sensor wiring.
