0.56-Inch Blue LED Display Digital Tachometer Motor Speed Value Measurement Module

1、Mini size, high performance and fast reaction speed. 2、0.56" LED 4-digits display, clear and easy for readings. 3、Rotate speed measuring range: 5-9999RPM; frequency range: 0-98990.1Hz. 4、Setting parameters will be memorized when power off. 5、Suitable for detecting the speed of every kind of motors.This tachometer, with mini size, high performance and fast speed, is greatly suitable for detecting the speed of every kind of motors. It can precisely test the rpm value for motors.Features:Mini size, high performance and fast speed.0.56" LED 4-digits display, clear and easy for readings.Rotate speed measuring range: 5-9999RPM; frequency range: 0-98990.1Hz.Setting parameters will be memorized when power off.Suitable for detecting the speed of every kind of motors.Tachometer Rate Setting Instructions:1. Rate range: 1-99(default 01: display value is same with actual value; if the rate is 10, display value*10=actual value);2. When power on, the meter display "0";3. Press "SET" button, display "1"; press again, display "01"...4. When display "1", is measuring RPM; press "ADD", from "1" to "2", when display "2", is measuring frequency; display "01" is for rate setting, short press "ADD" for +1, long press for +10;5. After setting the values, it will be stored if no operation in 10s, return the selected function interface;6. With 1 decimal point, that is when rotate speed is 1000RPM.Tips:User can set the appropriate rate so as to measure frequency, less than 100KHz (999.9*99=98990.1Hz).Specifications:Display: 0.56" 4-digit LEDDisplay Color: Blue / Green / Red (Optional)Rotate Speed Range: 5-9999RPMFrequency Range: 0-98990.1HzRate Setting Range: 1-99(default: 01)Reset Time: 10sRefresh Time: 120-1200RPM: 0.2~0.5s; 2400-9999RPM: 0.25~0.6sAccuracy: 5000RPM: Approx. 3RPMInput Signal: Voltage Pulse Signal, Active Contact Signal, PNP, NPNPower Supply: DC 8-15VInstallation: Embedded*Wiring:+12V: DC 8-15V Input PositiveGDN: DC Power NegativeIN+: Signal InputPanel Dimension: 72 * 36 * 20mm / 2.83 * 1.42 * 0.8inItem Weight: 25g / 0.88ozNote:The sensor is not included, this tachometer can not be used to test the car rotate speed separately.Package List:1 * Digital Tachometer1 * Digital Tachometer
