About this item

• 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 less than 1000RPM, the rotate speed corrects to 1st digit after the decimal point; no decimal point when more than 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 Range: 5-9999RPM Frequency Range: 0-98990.1Hz Rate Setting Range: 1-99(default: 01) Reset Time: 10s Refresh Time: 120-1200RPM: 0.2~0.5s; 2400-9999RPM: 0.25~0.6s Accuracy: less than 5000RPM: Approx. 2RPM; more than 5000RPM: Approx. 3RPM Input Signal: Voltage Pulse Signal, Active Contact Signal, PNP, NPN Power Supply: DC 8-15V Installation: Embedded *Wiring: +12V: 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.
