Walmeck High Digital with 0.56-Inch Red Display Motor Speed Measurement Module Speed Value Measurement

This with 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: size high performance and fast reaction speed. 0.56 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. 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. Tips: User can set the appropriate rate so as to measure frequency less than 100KHz (999.9*99=98990.1Hz).
