A multimeter is a multifunctional and multirange measuring instrument that is indispensable in electronic and electrical technology. Generally, a multimeter can measure direct current, direct voltage, alternating current, alternating voltage, resistance, and audio level, among others. Some can also measure capacitance, inductance, and certain parameters of semiconductors (such as β). Based on the display method, … Read more
① A good habit when using a multimeter is to check the dial setting before each measurement. Developing this habit will greatly reduce the chance of burning out the meter. ② Choose a range that keeps the pointer indicating around two-thirds of the full scale for more accurate readings. If you do not know the … Read more
