What is an Electrical Meter? How Many Types Are There and How Do They Work?

Electric meters are crucial tools for electrical and electronic work, one of which is the multimeter, an electric meter or current measuring device that can measure various electrical values. Electric meters have numerous benefits in both industrial and everyday life contexts. SCMA, a leading provider of measurement tools and automation solutions in Thailand, offers high-quality multimeters to customers along with SCMA services to promote the use of quality electric meters.

What is a Multimeter?

Electric meter

A multimeter (Multimeters) or electrical meter is an electric meter used to measure a variety of electrical parameters, including voltage, current, resistance, capacitance, frequency, diodes, and more. It combines the measurement capabilities of various types of meters into one device, such as voltmeters, ammeters, and ohmmeters. Multimeters can work with both direct current (DC) and alternating current (AC), making them essential multi-function electrical measuring tools for testing and troubleshooting various electrical circuits.

Benefits of Multimeters

Multimeters are one of the essential and widely used measuring tools in the electrical and electronics industry, both in industrial settings, craftsmanship, and general maintenance work. This versatile measuring tool offers numerous benefits that make work more convenient, accurate, and safer.

  • Used for testing electrical and electronic equipment, quickly identifying and fixing faults.
  • Used for quality control in manufacturing industries, testing the performance of devices according to standards.
  • Used for self-repair and maintenance of electrical issues without having to pay for labor costs.
  • A useful current measuring tool for research and study, helping to measure and record electrical data.
  • Increase safety in work by checking and warning of electrical hazards in advance.

Types of Multimeters

Multimeters are important electrical measuring tools that are widely used in electronics and electrical work due to their ability to measure various electrical parameters with a single instrument. Categorizing multimeters helps users select the appropriate tool for their specific job requirements and measurement needs efficiently.

Digital Multimeters (Digital Multimeters)

A digital multimeter is a modern electronic meter that displays measurement results as numbers on an LCD screen. It has internal systems that convert analog signals to digital, and includes current, voltage, and resistance measurements along with additional functions for ease of use, easy reading, and safety features. Suitable for high-precision work.

Analog Multimeters (Analog Multimeters)

An analog or needle multimeter is a traditional type that works by the movement of a needle on a standard scale, with multiple measurement ranges but not simultaneously. The system operates using magnetic fields, offering high accuracy and fewer errors, making it easier to read changes and more durable in various environments. However, its use is less convenient compared to digital types.

Clamp Meters (Clamp Meter)

A clamp meter is a multimeter with a jaw or clamp that measures electrical current without cutting the circuit. It is designed for portability, compact size, and numeric display, featuring range selection buttons and functions on the front panel. Suitable for measuring high currents and voltages in maintenance work or hard-to-reach areas, reducing risks and dangers during operation.

Pen-Type Multimeters

Pen-type multimeters, also known as pen meters, are small handheld electrical multimeters shaped like pens made of insulating plastic. They are compact, lightweight, and portable, using non-contact sensor technology to detect electricity with sound and light alerts via an LED display. Suitable for narrow or dark work areas, they quickly measure voltage and locate live circuits.

Reading a Multimeter

To use an electricity meter effectively, users must understand how to read the current measuring device correctly. This varies depending on the type of meter. A digital multimeter displays values as numbers on its screen for voltage, current, and resistance, while an analog multimeter reads values from where the needle points on a scale, which is divided into sub-ranges for each measurement type such as voltage ranges. The analog multimeter must be zeroed before use every time. Clamp-type multimeters focus on reading current by clamping around wires, whereas pen-style meters require touching or bringing close to what needs to be measured and then reading the value from the screen. However, it is crucial to select the correct measurement range according to approximate values to prevent damage to the electricity meter.
