Measurement accuracy: ± 0.1%, reading ± 1 word.2. Display mode: 0.56 red, green, blue LEDs3. Four-digit reading 10-9999 turns4.Display refresh rate:>3 times/sec.5.Working power supply:DC8-24V,30mA Also available in 5v power supply version.6. External dimensions: 79×42×25mm7.Installation size:76×39mm8.Hall sensor for NPN normally open type, Hall sensor detection distance within 10MM, Hall sensor installation diameter of 12MM, wiring length of 1.2MPrecautions for use:1. Connect the plug correctly according to the wiring diagram2. Strong electromagnetic interference should be avoided, and the measuring wire should be shielded or twisted pair.3. The counter's counting signal and zero signal input switch or circuit should be as close as possible to the counter's terminals, so that the signal line is as short as possible.4. avoid and other such as: strong electric wires or power wires and so on with the pipe or twisted wire, in order to avoid unnecessary interference, if necessary, please use shielded wires, shielding layer connected to the counting terminal "+".5. It is not recommended to use mechanical switch or microswitch, because their life is relatively short, after a time is easy to count by mistake; such as mechanical switch or microswitch, please try to use a better quality, so as to avoid counting by mistake, it is strongly recommended to use magnetic switch!Package Includes：Digital tachometer counter x1Hall switch x1
