Click👆Reserve the live broadcast to see the wonderful sharing from big company CEOs! Previously, we disassembled two low-cost multimeters, and also disassembled a more standard multimeter. We can see that the design of multimeters is basically similar, with differences in some design details and materials. This time we will dissect a different type of multimeter … Read more
1. Identifying the Start and End of Motor Windings Using a Multimeter When the six terminals of a three-phase asynchronous motor are lost, unclear, or rewound, it is necessary to determine which two terminals belong to the same phase, which is the start of the coil, and which is the end. Below are several methods … Read more

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

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
