How to use:
1. Place the tachometer disc on the turntable of the record player and turn on your turntable.
2. Turn on the strobe light, align the light to the tachometer disc , try to put it closer and about 5-10 CM is appropriate.
3. Eyes staring at the corresponding 33.3/45 speed stripe on the tachometer disc.
If the stripes of the LED light must be stable and not moving, the rotation speed is correct;
If the stripes on the disc are moving slowly clockwise, the turntable is running fast;
If the stripes on the disc are moving slowly anticlockwise, the turntable is running slow.
4. If your turntable is adjustable, please adjust the rotation speed of the disc until the corresponding speed strip stops.
5. If your turntable is not adjustable, first try a new drive belt. Drive belts can stretch over time causing minor speed variations. Great speed variations are more likely to be mechanical issues.
6. After adjusting the speed, remove the tachometer disc and put your vinyl record on the record player to hear the most accurate music.
