Tips: How to adjust the gear ratio of the waterproof digital RPM meter?

1. Press and hold the black rubber button on the digital meter for 3 seconds to enter the gear ratio setting mode. If the button is released for 3 seconds, the tachometer will exit the setting mode and automatically save the adjusted data.
2. Once in setting mode, hold the button to increase the value continuously. Release the button, then press and hold it again to decrease the value continuously. The gear ratio adjustment range is from 1 to 300. Adjust to the desired gear ratio and release the button for 3 seconds to automatically save the value.
3. If the sensor is installed on the flywheel, the gear ratio value equals the number of engine gears. If the RPM signal is taken from the W-point signal, the gear ratio value equals half the number of poles (Poles/2).
