Introducing the 0.28-inch 4.5-30V Two-Wire DC Voltmeter with a vibrant red LED display—a compact solution for hassle-free voltage measurement. Setting it up takes just a few minutes; connect the red wire to the positive pole and the black wire to the negative pole, and the LED display will start blinking.
With reverse polarity protection, you’re covered even if there’s a mix-up in wire connections. This voltmeter operates without an external power supply, directly measuring voltages within the 3.5-30V range. For precise measurements, the decimal point automatically adjusts based on the voltage—displaying two decimal places below 10V and one decimal place above 10V.
Ideal for monitoring storage battery voltage in motorcycles and cars, this voltmeter provides insights into battery status. It’s versatile enough for other voltage measurement applications. With a maximum operating voltage of 30V, ensure a margin during operation to prevent permanent damage from electrical sparks, power supply ripple, or abrupt voltage changes.
Featuring a bright and clear LED display, this voltmeter is your reliable tool for measuring DC voltages in the range of 4.5V to 30V.
Connections:
Red Wire: source +ve terminal.
Black Wire: Source -ve terminal.
Features:
- Don’t need the external power supply because it is a self-powered version of this display.
- Best operates in the working voltage range of 5V to 24V
- 100% Brand new and high quality.
