0.36″ 2.5-30 Volt 2 Wire DC Voltmeter – Digital

Feature:

The measurement range of the voltmeter is 0-30V. This voltage is only a measurement signal and cannot be used as the working power supply of the voltmeter.

Therefore, the voltmeter needs to provide 5-30V DC voltage from the outside as the working power supply.

Among the three wires, the black wire is the common negative pole, the white wire is connected to the positive pole of the measurement voltage, the red wire is connected to the positive pole of the working power supply, and the total negative pole in the meter

Measuring range ：0V-30V / 0-100V

Two wires =DC30.0V。 Note: Input voltage higher than 30V may be permanently damaged!

Three wires = 0-100V, but can not use a large current, otherwise it will damage the product

Allowable error：±1%； When it is greater than or equal to 10V, the error is ± 0.3V; Error ± 0.10 when less than 10V

Understanding the DC Voltmeter

Introduction

In the realm of electronics, understanding and measuring voltage is paramount. A crucial tool in this endeavor is the DC voltmeter, often referred to simply as a voltmeter.

But what exactly is a DC voltmeter, and how does it function? In this comprehensive guide, we will delve into its definition, applications, and inner workings to provide you with a thorough understanding of this indispensable electronic instrument.

Definition and Purpose

A **DC voltmeter** is an electronic measuring device designed to measure and display direct current (DC) voltage levels. Unlike its AC (alternating current) counterpart, which measures the fluctuating voltage of alternating current, a DC voltmeter is tailored specifically for the stable, unidirectional flow of current in electronic circuits.

### How Does a DC Voltmeter Work?

At its core, a DC voltmeter operates on the principle of the voltmeter movement—a sensitive electromagnetic mechanism.

When voltage is applied to the voltmeter, it causes a current to flow through a coil, generating a magnetic field. This field interacts with a permanent magnet, resulting in a rotational force that moves a pointer across a calibrated scale, indicating the measured voltage.

## Applications of DC Voltmeters

DC voltmeters find widespread use across various industries and applications due to their precision and reliability. Some common applications include:

1. **Electronics Testing**: Assessing the voltage levels in electronic circuits to ensure proper functioning.
2. **Power Supply Monitoring**: Verifying the output voltage of power supplies to guarantee stable and consistent power delivery.
3. **Battery Testing**: Checking the voltage of batteries to determine their charge status and overall health.
4. **Automotive Diagnostics**: Troubleshooting electrical systems in vehicles by measuring voltage levels.
5. **Industrial Automation**: Monitoring voltage in automated processes to prevent electrical failures.

## Advantages of Using DC Voltmeters

### Accuracy and Precision

DC voltmeters are known for their high degree of accuracy in measuring voltage levels. This precision is crucial in critical applications where even a slight deviation from the specified voltage can lead to malfunctions or damage.

### Ease of Use

With clear and intuitive displays, DC voltmeters are user-friendly even for those with limited technical expertise. The straightforward readouts make them accessible tools for both professionals and hobbyists.

### Over voltage Protection

Many modern DC voltmeters come equipped with over voltage protection mechanisms. These safeguards prevent damage to the voltmeter in cases of excessive voltage, ensuring its longevity and reliability.

To ensure the longevity and accuracy of your DC voltmeter, consider the following maintenance tips:

1. **Keep it Clean**: Regularly wipe the voltmeter with a clean, dry cloth to remove dust and debris.

2. **Store Properly**: When not in use, store the voltmeter in a cool, dry place away from direct sunlight or extreme temperatures.

3. **Calibration Check**: Periodically verify the accuracy of your voltmeter using a known voltage source or a calibration device.
