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 x10=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 first digit after the decimal point; no decimal point when >1000RPM.
Package Includes: 1 x Digital Tachometer
note: User can set the appropriate rate so as to measure frequency, less than 100KHz (999.9x99=98990.1Hz).
The sensor is not included, this tachometer can not be used to test the car rotate speed separately.
Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand.
Please allow 0-1cm error due to the manual measurment.
