Multimeters & Accessories

We offer a great range of hand-held analog and digital multimeters and their accessories from top brands such as Fluke, ISO-TECH, Keithley, Keysight Technologies and Chauvin Arnoux, as well as our own RS PRO range.

What is a Multimeter?

Multimeters are essential electronic measuring tools that combine multiple functions into one handy device, allowing users to measure voltage, current, and resistance. These versatile tools save engineers and electricians significant time by accurately detecting faults in a wide range of devices, appliances, wiring, circuits, and power supplies.

Most multimeters are handheld for convenience, making them easy to use in various settings. Some models feature advanced capabilities, such as graph displays, while others come with an IP rating for waterproofing, enabling their use in wet conditions. Whether you're looking for analog multimeter parts or digital multimeter parts, buy from RS in the Philippines to have a reliable multimeter for effective electrical testing and diagnostics.

Types of Multimeter

There are essentially two types of multimeters:

Analog

Analog multimeters are classic devices that measure electrical values using their parts, such as a moving needle and a scale, providing readings in continuous value ranges. These multimeters are particularly useful testers for observing trends and fluctuations in measurements, as the needle's movement can indicate subtle changes in voltage, current, or resistance. While they may lack the precision of digital counterparts, analog multimeters are valued for their simplicity and reliability in various applications, especially in educational settings and certain industrial environments.

Digital

Also known as a DMM, a digital multimeter makes use of electronic parts to measure accurate increments. They measure in analog first and then convert to digital. For this reason, there is a delay, and they might not be the best option for values that are constantly changing. They are, however, very precise in their measurements, and are the best choice for accuracy. These digital multimeters can be further broken down into three types:

• Fluke: This type of meter is the most popular digital multimeter for measuring electrical resistance and voltage, and it often includes various additional functions.
• Clamp Digital: A digital multimeter designed to measure electrical current flow. The clamp measures the amperage while the probe measures the voltage.
• Autoranging: This digital multimeter is the easiest and safest to use, as it automatically adjusts to the measurement without needing to be switched with a central knob; a value is always displayed, regardless of what is being measured.

What can Multimeters Measure?

Multimeters are versatile devices that measure a wide range of electrical values, making them essential tools for professionals in various fields, such as automotive, HVAC, and industrial settings. The ability to accurately measure multiple parameters makes them indispensable for diagnosing electrical issues in residential and commercial environments.

Here are some other values that you can measure using multimeters:

• Frequency
• Inductance
• Resistance (ohms)
• Conductance (siemens)
• Alternating voltage
• Direct voltage
• AC or DC electrical current
• Capacity (farads)
• Decibels
• Duty cycles
• Temperature (Celsius or Fahrenheit)

**Choosing the Right Multimeter

For HVAC Systems and Automotive Testing**

When selecting a multimeter for HVAC systems and automotive testing, it’s essential to choose one that offers specialized features tailored to these applications. Look for multimeters with temperature measurement capabilities, capacitance testing, and true RMS functionality to accurately measure complex signals. A robust, durable model with a clear display will also enhance usability in demanding environments, ensuring precise diagnostics for heating, ventilation, air conditioning, and automotive electrical systems.

Benchtop and Portable Multimeters

Benchtop multimeters and portable multimeters serve different purposes and are suited for specific applications. Benchtop multimeters, designed for laboratory settings, typically offer higher accuracy, greater resolution, and more features, making them ideal for detailed measurements and testing. In contrast, portable multimeters are lightweight and compact, perfect for fieldwork and on-site testing. They provide convenience and ease of use, allowing technicians to quickly troubleshoot electrical issues in various environments. Choosing between them depends on your specific needs for accuracy versus portability.

Multimeter Accessories and Parts

Common Accessories and Replacement Parts

Multimeters come with a variety of accessories and replacement parts that enhance their functionality and usability. Common accessories include carrying cases, protective covers, and calibration standards. For analog and digital multimeters, replacement parts such as display screens, internal batteries, and circuit boards ensure your device remains operational. You can buy these parts from RS in the Philippines to maintain accuracy and extend the lifespan of your multimeter, making it essential for professional and DIY applications.

Tester Leads, Fuses, and Adapters

Tester leads, fuses, and adapters are critical accessories for multimeters, particularly in high-voltage and high-current applications. Quality tester leads ensure reliable connections and accurate measurements, while fuses protect your multimeter from overloads and prevent damage during testing. Adapters expand the versatility of your multimeter, allowing it to interface with various devices and measuring scenarios. Together, these parts enhance electrical safety and performance, making them indispensable as electrical testing tools.

Installation and Maintenance Tips for Multimeters

Proper installation and maintenance of multimeters are crucial for ensuring their longevity and accuracy. When setting up your multimeter, follow the manufacturer’s guidelines to ensure correct connections and prevent damage. Regularly inspect the device for signs of wear, and keep the terminals clean to ensure accurate readings. In case of any damage, it's reassuring to know that multimeter replacement parts are readily available, allowing you to replace any broken components and extend the life of your multimeter tester.
