ITEM NAME:0.28 inch Digital Direct Voltage Gauge Head 2 Line DC4-30V (Yellow Green) A#S Product Description Description: 0.28 inch Small Digital Direct Voltage Gauge Head with LED Number Show Adjustable Dual Line DC4-30V for Batteries Universal Feature: 1. Range: 2.6-30V (Yellow) 2.6-30V (Green) 2. Equipped with two wires, the wiring is convenient and simple, easy to access the car/battery car/motorcycle interior line. 3. It has reverse connection protection function, the wiring will not be burned, and has fine-tuning function. 4. Pay attention to the use of the most. High input voltage should not exceed 40V, otherwise there will be danger of burnout. 5. When the voltage is less than 3.0V, the brightness of the display will darken, but it does not affect the correct measurement. 6. When measuring the voltage below 10V, two decimal points will be displayed after the decimal point; when measuring the voltage above 10V, one decimal point will be displayed after the decimal point. It can not only meet the needs of battery users for measuring accuracy, but also meet the needs of measuring higher voltage. Specifications: Working voltage: DC2.4~40V (with reverse connection protection function) Detection voltage: DC2.4~30V Working current:
