Precautions for use:
1. Connect the plug correctly according to the wiring requirements.
2. Should avoid strong electromagnetic interference, the measurement wire is best to use shielded wire or twisted pair.
3. The counter signal and the switch or circuit of the clear signal input should be as close as possible to the terminal of the counter to make the signal line as short as possible.
4. Avoid with other wires such as strong electric wires or power wires or stranded wires to avoid unnecessary interference. If necessary, use shielded wires and the shield is connected to the counting terminal “+”.
5. It is not recommended to use mechanical switches or micro switches, because their life is relatively short, it is easy to count down after a long time; if using mechanical switches or micro switches, please try to use better quality, so as not to count errors, strong Recommended magnetic switch.
Pacage Include:
1 × Blue LED tachometer
1 × Hall Proximity Switch Sensor NPN

Sensor only works with the magnet oriented one way. Wiring diagram in English would be good. I still don’t know what the number 4 wire does
