The reason a multimeter can measure current, voltage, and resistance lies in its use of a sensitive galvanometer. When a small current passes through the meter, the needle will indicate a value. However, the galvanometer cannot directly handle large currents, so it is necessary to connect some resistors in parallel or series with the galvanometer … Read more

The multimeter, also known as a multitester, is a multifunctional measuring instrument. Generally, a multimeter can measure DC current, DC voltage, AC voltage, resistance, and audio levels. Some can also measure AC current, capacitance, inductance, and parameters of semiconductors. It is a simple and practical measuring instrument. Nowadays, the most mainstream multimeters are digital multimeters, … Read more
Correctly using a multimeter can quickly and accurately identify faults, and prevent damage to both electrical devices and the multimeter itself. 1. Check Range Before Measuring Every time you pick up the probes to measure, always double-check whether the measurement category and range selection switch are set correctly. For safety, this habit must be developed. … Read more
