Digital Multimeter for Beginners Step by Step Guide on how to effectively use your digital multimeter A digital multimeter is an indispensable tool for testing, diagnosing, and troubleshooting electrical circuits, components and devices. The first digital multimeter was introduced in the late-1970s, and has proven much more accurate and reliable than the old needle-based analog meters. It's used primarily to measure voltage (volts), current (amps), and resistance (ohms). But that's just the beginning of what this surprisingly useful tool can do. This book will show you how to use a digital multimeter to diagnose circuits, learn about other people's electronic designs, and even test a battery. Hence the 'multi'-'meter' (multiple measurement) name. The most basic things we measure are voltage and current. A multimeter is also great for some basic sanity checks and troubleshooting. Is your circuit not working? Does the switch work? Put a meter on it! The multimeter is your first defense when troubleshooting a system. In this tutorial we will cover measuring voltage, current, resistance and continuity. GRAB YOUR COPY NOW!!!

#### CHAPTER ONE: INTRODUCTION

Do you desire to learn how to make use of a multimeter? I have put this book together so you could learn the best way to utilize a digital multimeter (DMM), a basic device that you can use to analyze circuits, find out about others' electronic designs, and even test a battery. Thus the 'multi'- 'meter' (multiple measurement) name.

The most fundamental things we measure are voltage and current. A multimeter is likewise extraordinary for some fundamental once-overs to make sure everything seems ok and investigating. Is your circuit not working? Accomplishes the switch work? Put a meter on it! The multimeter is your first guard while investigating a framework. In this book webe considering how to measure current, voltage, resistance and continuity.

We will utilize the SparkFun VC830L all through the instructional exercise, however these strategies ought to apply to most multimeters.

Different parts of a Multimeter

A multimeter is has three sections:

• Display

• Selection Knob

• Ports

The display typically has four digits and the capacity to show a negative sign. A couple of multimeters have enlightened presentations for better review in low light circumstances.

The selection knob could allow you to set your multimeter so you would be able to read different variables like voltage (V), resistance (Ω) and milliamps (mA).

Connect two probes to two of the ports on the face of the unit. COM represents normal and is quite often associated with Ground or '- ' of a circuit. The COM test is customarily dark yet there is no contrast between the red test and dark test other than shading. 10A is the extraordinary port utilized when estimating huge flows (more prominent than 200mA). mAVΩ is the port that the red test is traditionally connected to. This port permits the estimation of current (up to 200mA), voltage (V), and resistance (Ω). The tests have a banana type connector on the end that connects to the multimeter. Any test with a banana fitting will work with this meter. This takes into account various sorts of tests to be utilized.

Probe Types

There are a wide range of probes of tests accessible for multimeters.

Below we have a list of our top choices;

• Banana to Alligator Clips : These are extraordinary links for interfacing with huge wires or pins on a breadboard. Useful for performing longer term tests where you don't must have to hold the tests set up while you control a circuit.

• Banana to IC Hook : IC hooks function admirably on littler ICs and legs of ICs.

• Banana to Tweezers : Tweezers are convenient on the off chance that you are expecting to test SMD parts.
