Multimeters are hand-held measurement devices designed to measure the electrical properties of multiple electrical circuits and appliances. A multimeter measures electrical values, such as current, voltage, and resistance, in various environments, including homes, industries, laboratories, and workshops. They are essential devices required for the maintenance, testing, and repair of various electrical circuits employed by technicians and engineers to make convenient and efficient measurements.
Furthermore, they come in multiple forms suitable for specified spaces and applications. For instance, a hand-held digital multimeter (DMM) is suitable for home applications, whereas bench multimeters are used in workshops.
The Basic Function and Work Differences of Multimeters
The major function of multimeters is to measure electrical resistance, voltage, and current within circuits and to diagnose, troubleshoot, and test them. The two types, analogue, and digital multimeters, essentially perform the same function; however, they differ in their designs to give output. There are also multimeters with multiple functions that vary based on cost, design, and features.
There are Two Types of Multimeters
- Digital Multimeters: These advanced multimeters feature an LCD to provide precise readings in digital (numbers) form. They are the preferred multimeters for most technicians and engineers due to their robust operation and high accuracy measurements.
- Analogue Multimeters: Unlike digital multimeters, analogue multimeters are test meters that show their readings using a needle scale. These measuring devices feature an analogue display and indicate the measurement level using pointer deflection. They are most often used in environments where the measured values are required to be displayed on control panels.
What are the Typical Checks They Perform?
These measurement devices can typically check:
- Resistance
- Current in circuits
- AC or DC voltages
- Electrical components’ continuity
- Frequency, True RMS voltage, and current readings (by advanced models).
Where are Multimeters Used?
Multimeters are widely used devices in multiple environments with a plethora of applications, including:
- Industries
- Workshops
- Electronic testing
- Commercial wiring installation
- Automotive
- Laboratories
- Shops
- Educational institutes.
