A clamp multimeter is composed of a current transformer and a current meter. The core of the current transformer can open when the lever is squeezed; the wire carrying the current to be measured can pass through the gap of the opened core without being cut. When the lever is released, the core closes. A … Read more
A multimeter, also known as a multi-tester or volt/ohm meter, is a multifunctional, multi-range measuring instrument. It is the most basic tool in the field of electronic testing and is widely used; it is a measuring tool that personnel in the electronics industry must master. Multimeters are divided into pointer and digital types. A typical … Read more
1. Measuring Capacitor Health with an Analog Multimeter To measure the health of a capacitor, it is best to use an analog multimeter as it provides a more intuitive reading. Here, we will use an analog multimeter to illustrate how to measure a capacitor’s health. First, to measure the capacitance, set the multimeter to the … Read more
A clamp multimeter is composed of a current transformer and a multimeter. The core of the current transformer can open when the clamp is squeezed; the wire through which the measured current flows can pass through the gap in the opened core without needing to be cut. When the clamp is released, the core closes. … Read more
