Digital Mini Voltmeter Gauge Tester 5-Pack

Product Specifications and Features

This DC 0-30V Voltmeter offers precise voltage measurement capabilities with dimensions of 23mm x 15mm (0.9" x 0.59") and a thickness of 10mm (0.39"). It is equipped with a mounting hole center distance of 28mm. The voltmeter operates within a voltage range of DC 3V to 30V and measures voltages accurately with a resolution of 0.01 (for voltages between 0.01V to 9.99V) and 0.1 (for voltages between 10.0V to 30.0V).

Featuring a three 0.36" digital LED tube display, this voltmeter ensures clear visibility and readability. The measurement rate is 300mS per reading. It functions reliably within an operating temperature range of -10°C to 65°C (14°F to 149°F) and includes built-in reverse polarity protection to prevent damage due to incorrect wiring.

Voltage Display and Wiring

When measuring voltages below 10V, the voltmeter displays two decimal digits (e.g., 5.32V). For measurements above 10V, it displays one decimal digit (e.g., 10.5V). The wiring configuration includes a red wire for power supply positive (+), a black wire for power supply negative (-), a white wire for measured voltage positive (+), and the measured voltage negative (-).

Package Contents and Installation

The package includes 5 units of DC 0-30V Voltmeter. Installation is straightforward with a three-wire connection setup, ensuring accurate voltage testing capabilities. It is crucial to note that this voltmeter is calibrated to measure voltages from 0.00 to 30V accurately. Two-wire meters lack the capability to measure voltages below 3V effectively.

Calibration and Maintenance

For precise measurements, the voltmeter can be calibrated using the adjustment screw located on the back. This feature allows users to maintain accuracy over time, ensuring reliable performance in various applications.

User Experience and Durability

Users can expect a bright and clear display experience, thanks to the blue-colored LED tubes. The voltmeter is designed to be durable and reliable, making it suitable for monitoring voltage in automotive applications such as cars, motorcycles, and batteries. It is engineered to withstand regular use and offers protection against voltage spikes and reverse polarity.

Safety and Usage Recommendations

To prevent damage, ensure that the measured voltage does not exceed 30V. Exceeding this limit could potentially harm the voltmeter and compromise its functionality. The device's robust construction and protective features make it a dependable choice for both professional and DIY enthusiasts seeking accurate voltage monitoring solutions.

In summary, the DC 0-30V Voltmeter combines precision, reliability, and user-friendly features, making it an ideal tool for a wide range of voltage monitoring applications. Whether used in automotive diagnostics or battery maintenance, its bright display and durable design ensure consistent performance and accurate readings.
