Irfora High Digital Tachometer with 0.56-Inch Red LED Display Motor Speed Measurement Module Speed Value Measurement

Please note, this item ships from an international seller. Expected delivery is 10-15 days. This tachometer, with mini size, high performance and fast reaction 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 reaction speed. 0.56" LED 4-digits display, clear and easy for readings. Rotate speed measuring : 5-9999RPM; frequency : 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 : 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, the rotate speed corrects to 1st digit after the decimal point; no decimal point when >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 LED Display Color: Blue / Green / Red (Optional) Rotate Speed : 5-9999RPM Frequency : 0-98990.1Hz Rate Setting : 1-99(default: 01) Reset Time: 10s Refresh Time: 120-1200RPM: 0.2~0.5s; 2400-9999RPM: 0.25~0.6s Accuracy: <5000RPM: Approx. 2RPM; >5000RPM: Approx. 3RPM Input Signal: Voltage Pulse Signal, Active Signal, PNP, NPN Power Supply: DC 8-15V Installation: Embedded *Wiring: +: DC 8-15V Input Positive GDN: DC Power Negative IN+: Signal Input Panel Dimension: 72 * 36 * 20mm / 2.83 * 1.42 * 0.8in Item Weight: 25g / 0.88oz Note: The sensor is not included, this tachometer can not be used to test the car rotate speed separately.
