Understanding Common Symbols on Multimeters Types of electrical measurements and switch positions: ACV (or V) — AC voltage range, typically includes 2.5V, 10V, 50V, 250V, 500V, etc. DCV (or V) — DC voltage range, typically includes 0.5V, 2.5V, 10V, 50V, 250V, 500V, etc. DCmA (or mA) — DC milliamp range, … Read more
How to Measure Leakage Current with a Multimeter? How to measure leakage current with a multimeter, methods for measuring leakage current. Using the continuity setting of the multimeter, measure the ground against the part of the circuit being tested. If the meter shows a resistance value, it indicates that there is no insulation. However, in … Read more
A digital multimeter is an electronic instrument used for electrical measurements. It can have many special functions, but its main functions are measuring voltage, resistance, and current. As a modern multipurpose electronic measuring instrument, it is primarily used in the fields of physics, electricity, and electronics. In daily life, you may encounter situations where household … 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
