Connect the plug correctly according to the wiring diagram 2. Should avoid strong electromagnetic interference and it is better to use shielded wire or double stranded wire for measuring conductors 3. The counting signal of the counter and the switch of the zero clearing signal input or the circuit shall be as close as possible to the terminal of the counter to make the signal line as short as possible 4. Avoid with other such as: high voltage wires or power wires and so on4 Digital LED Tachometer RPM Speed Meter & NPN Hall Proximity Switch Sensors BUDescriptionFeature:Working power supply: DC8-24V, 40mA Display mode: 0.56"LED,4 Digital.measurement range: 10-9999RPMMeasuring Accuracy: 0.1, reading 1 word.Display refresh rate: >3 times/secOverrange display: the first one shows "1" or "-1", and the latter three do not showPhysical dimension: 79x43x26mm Precautions:1.
