Voltímetro digital LED de 0,56 "DC 3,5-30 V pantalla de voltaje de 2 cables para batería Panel solar coche motocicleta

Product description:

1, this simple voltmeter wiring, then only two lines, connected to the positive red, black to negative, reversal protection has inner, reverse do not burn.

2, the external operating supply voltage without meter, can be operated directly measuring the voltage, wide operating voltage range 4.5-30V.

3, is reached. Good measurement accuracy, will automatically move the decimal point positions are different according to the voltage table according to the measured voltage. Measuring voltages below 10V

When, after the decimal point two; when measuring voltage above 10V, a decimal point display.

4, the voltmeter may be for motorcycles, automobiles and the like to monitor battery voltage, battery state grasp. It can also be used for other purposes voltage measurement.

Note things out:

1,30V a voltmeter of high voltage limit use, please pay attention to the table leave enough margin to use, to avoid sparking motors, power supply ripple

Or other high voltage mutations cause damage to the long-yong voltmeter.

2, the voltmeter without making moisture-proof, waterproof, shockproof, oil processing, use note, or themselves.
