How to Use:1. Cut a hole with a diameter of 85 mm in the instrument's mounting plate and ensure there is at least 55 mm of space behind the instrument. 2. Place the counter in the open hole and tighten the back cover after adjusting its position. Settings: 1. Press and hold the rubber button on the back of the counter for 3 seconds to enter setting mode. Releasing the button for longer than 3 seconds will exit setting mode. 2. Press and hold the button; the value will continue to increase. Release the button while still holding it; the value will continue to decrease. The longer the button is held down, the faster the value counts. The minimum counting increment is 0.1, and the adjustable range is 1.0 to 360. 3. After adjusting the gear ratio to your requirements – the number of teeth on the flywheel – please release the button. After 3 seconds, the tachometer will automatically save your settings.
