Testing Diodes with a Multimeter

Introduction In this blog, we will describe what diodes are, how they function, and how to test them. We will identify two of the most common types of diodes encountered by Technicians, and describe how to test them in circuit and out of circuit. Additionally, we will discuss the most common ways that diodes fail […]

How to Test Diodes – LEDs, Microwave, Zener, and Standard

How to test Different Types of Diodes Testing diodes is primarily a matter of checking the forward and reverse bias voltages. LEDs have a higher forward bias than most diodes. The high-powered ones used for lighting usually cannot be tested with the diode check function on your meter nor with a simple resistance check. The […]
