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

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 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, 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).
