★ Digital multimeters are widely used in people’s daily life and study due to their simplicity, digital display, ease of operation, and strong anti-interference capabilities. This article briefly describes the common faults encountered during the use of digital multimeters and provides some daily handling methods. 1. Several Common Fault Analysis Methods for Digital Multimeters 1.1 … Read more
Using a multimeter to measure circuit faults is one of our common methods. Here, I will discuss how to use a multimeter to check for circuit faults. When we check for circuit faults with a multimeter, we mainly use three ranges of the multimeter for measurement: First, use the resistance range to measure the resistance … Read more
Oscilloscope, as its name implies, is a machine that displays waveforms, and it is also known as the “eye of the electronic engineer.” Its core function is to display the actual waveform of the measured signal on the screen, allowing engineers to locate problems or evaluate system performance, among other tasks. Its development has also … Read more
