Get Started with the Right Multimeter and Clamp Meter Pairing

If you are new to electrical work, field service, or even serious DIY projects, your test tools are crucial. To begin, a digital multimeter (DMM) and a clamp meter combination are essential if you plan to work on any electrical system.

This pairing provides the foundation for your test tool kit, enabling you to test safely, diagnose confidently, and work efficiently from the start. However, selecting the right pair is challenging.

Fluke offers a variety of DMM and clamp meter combinations to suit diverse testing needs. This guide explains the function of each tool and presents optimal options for your specific applications and objectives.

Why You Need Both a Multimeter and Clamp Meter

A digital multimeter (DMM) measures various electrical values such as voltage (AC/DC), low-range current, resistance, continuity, frequency, and sometimes temperature or capacitance. It uses test leads that connect to exposed wiring or terminals. You will use it to verify control board outputs, check sensor signals, or measure resistance across a fuse, among other specific tasks.

A clamp meter measures current without breaking the circuit. Its jaws clamp around a live conductor to measure the current flowing through it. Most clamp meter models also measure voltage, resistance, and continuity using test leads.

Here is a comparison:

• The DMM provides more detailed insights and can perform a wider range of measurements. However, you may not be able to use it safely in all situations where live current is present.
• A clamp meter enables safe, fast current measurements, particularly in tight panels or with multiple conductors. However, it offers fewer measurement capabilities than a DMM, so it cannot provide a comprehensive assessment of asset condition.

Together, these tools offer a broader range of measurement capabilities and flexibility for both field and lab measurements. Different situations require specific tools, and having both a DMM and a clamp meter ensures you are prepared for any task.

Selecting the Right Multimeter and Clamp Meter Pair

Fluke manufactures a wide variety of digital multimeters (DMMs) and clamp meters for diverse environments and applications. Your specific application will determine the features and specifications required to complete tasks effectively and achieve optimal value.
