Digital Multimeter

What is a digital multimeter?

A digital multimeter (DMM) is an electronic measuring instrument that reads and displays multiple electrical measurements, commonly including voltage (AC/DC), current (AC/DC) and resistance, on a digital screen.:contentReference[oaicite:3]{index=3}

What can a digital multimeter measure?

Modern digital multimeters measure voltage, current, resistance, continuity, diode testing and, in many cases, additional parameters such as capacitance, frequency and temperature when equipped with the right functions.:contentReference[oaicite:4]{index=4}

What is True RMS and why is it important?

True RMS (Root Mean Square) is a measurement method that provides accurate readings on non-sinusoidal AC signals and complex waveforms. True RMS multimeters are preferred for more accurate field testing.:contentReference[oaicite:5]{index=5}

How do I choose the right multimeter?

Select a multimeter based on the functions you need (voltage, current, resistance, frequency, capacitance), safety rating (CAT), display counts and whether auto-ranging or True RMS features are required. Higher accuracy and function sets are ideal for professional use.:contentReference[oaicite:6]{index=6}

What safety features should I look for?

Look for multimeters with appropriate CAT safety ratings for your application, high initial input impedance, over-load protection and quality fuse protection to safeguard both the user and the instrument.:contentReference[oaicite:7]{index=7}

Where are digital multimeters used?

Digital multimeters are widely used in electrical installation, maintenance work, motor and control panel testing, electronics diagnostics, automotive troubleshooting and laboratory measurements.:contentReference[oaicite:8]{index=8}
