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
How to use a multimeter to check if the water pump motor coil is burned out? To determine the quality of the motor, three conditions must be measured: the absence of open circuits and short circuits between the coil windings, and the insulation resistance. First, check whether the motor is a three-phase motor or a … Read more
