DC 8-18V X6 Waterproof Digital Voltmeter 12V Car Boat Motorcycle 0.56inch LED Display Volt Voltage Meter Mini Tester Panel

Type1

Feature:

1. This voltmeter adopts a fully enclosed shell design, soaked in water for a short period of time and can work normally without damage. 2. The voltmeter is small in size and is displayed by three 0.56-inch LED digital tubes. 3. Two-wire system wiring, simple wiring; direct measurement, no external auxiliary power supply. 4. This voltmeter can be used to detect battery voltage in motorcycles, automobiles, etc., and to grasp the battery status in time. Product size:56mm*31mm*13.5mm Measurement accuracy:±1V Voltage range :8-18V Line length :100cm Power supply mode :DC DC two lines Display mode Three :0.56" LED digital tube Waterproof rating :X6 Shell material :ABS Wiring Method: Red line connect ”+“    ;  Black line connect "-" NOTE: 1. The power supply voltage used in this voltmeter should not be higher than 12V. Please pay enough attention to the table to avoid residual damage to the voltmeter due to motor spark, power supply rple or other exceive abrupt voltage. 2. Since this voltmeter uses LED display, it requires a certain working current, so it cannot be used for high internal resistance voltage measurement, such as weak signal voltage and on battery. 3. Pay attention to the wiring method, the red line is positive, the black line is negative, and it cannot be reversed.
