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

This Digital Tachometer offers mini size, high performance, and a fast reaction speed, making it ideal for detecting motor speeds. It accurately measures RPM for all types of motors.

Features:

• Compact size with high performance and fast reaction speed.
• 0.56" LED 4-digit display for clear and easy readings.
• Rotation speed measuring range: 5-9999 RPM; frequency range: 0-98990.1 Hz.
• Settings are retained even when powered off.
• Suitable for speed detection of all types of motors.

Tachometer Rate Setting Instructions:

1. Rate range: 1-99 (default is 01: display value is the same as actual value; if the rate is 10, display value x 10 = actual value).
2. Upon power on, the meter displays "0".
3. Press "SET" button to display "1"; press again to display "01"...
4. When displaying "1", it is measuring RPM; press "ADD" to change from "1" to "2". When displaying "2", it measures frequency; display "01" for rate setting, short press "ADD" for +1, long press for +10.
5. After setting values, they will be stored if no operation occurs within 10 seconds, returning to the selected function interface.
6. Includes 1 decimal point for rotation speed <1000 RPM; no decimal point for >1000 RPM.

Tips: Users can set the appropriate rate to measure frequency, less than 100 kHz (999.9 x 99 = 98990.1 Hz).
