0.28 Inch 0-100V Three Wire DC Voltmeter
This compact digital voltmeter features a red LED display and is designed for measuring DC voltages from 0 to 100V. The 0.28-inch Digital Voltage Tester is easy to configure, requiring just a few minutes to connect the wires and start measuring voltage.
To use, simply connect the red wire to the positive terminal, the black wire to the negative terminal, and the yellow/white wire to the positive terminal of the source you want to measure. When measuring the voltage of another power source, ensure the negative pole is common. Don’t worry about wire misconnection—this voltmeter includes reverse polarity protection, preventing damage to the circuit.
The voltmeter requires an external power supply ranging from 0V to 100V. For enhanced accuracy, the voltmeter automatically adjusts the decimal point based on the voltage being measured. For voltages below 10V, it displays two decimal places; for voltages above 10V, it displays one decimal place.
This compact voltmeter features a bright and clear LED display, capable of measuring DC voltages in the range of 0V to 100V. Its small size (just 0.28″) and lightweight design make it highly portable and easy to carry. The vivid blue LED display provides sharp, easy-to-read readings, even in low light conditions or at low operating voltages.
This voltmeter is ideal for measuring the voltage of storage batteries in motorcycles and cars, allowing you to easily monitor the battery’s health and status. It can also be used to measure other DC voltages. The voltmeter has a maximum operating voltage limit of 100V. To ensure its longevity and prevent permanent damage, be sure to provide adequate voltage margin during operation. Avoid exposing the voltmeter to electrical sparks, power supply ripple, or sudden voltage spikes that exceed its rated capacity.
Connections :
- Red Wire: Positive of the Power supply
- Black Wire: Negative of the Power supply and also used as the negative of the measurement voltage source
- Yellow/White/Blue: Positive of the measurement voltage source
Note:
- 2-power source (Red and Black) line with the highest input voltage cannot exceed 100V, otherwise, there is the risk of burnt.
- Three-line voltage range 0-100V, but also can be used as second-line use in 40V voltage to within Technical parameters
The display weight and Dimensions may have ±2% error.
