Here are some tips on how to use a multimeter
A multimeter, also known as a multimeter, multimeter, or multimeter, is a multifunctional and multi range measuring instrument. Generally, a multimeter can measure DC current, DC voltage, AC voltage, resistance, and audio level, and some can also measure AC current, capacitance, inductance, and some parameters of a semiconductor. It is a simple and practical measuring instrument.
The most mainstream commonly used multimeters nowadays are digital multimeters, and pointer multimeters are rarely used. A digital multimeter is relatively simple measuring instrument. As a multi-purpose electronic measuring instrument, it generally includes functions such as ammeter, voltmeter, ohmmeter, etc., sometimes also known as multimeter, multimeter, multimeter, or multimeter. A multimeter has a wide range of applications. Below, we will explain the basic usage methods and mnemonics of a multimeter.
Instructions for using a multimeter
(1) Before using a multimeter, it is necessary to perform a "mechanical zeroing", which means that when there is no measured power, the multimeter pointer should be placed at the zero voltage or zero current position.
(2) During the use of a multimeter, do not touch the metal part of the probe with your hands. This ensures accurate measurement and personal safety.
(3) When measuring a certain amount of electricity, it is not advisable to shift gears at the same time, especially when measuring high voltage or high current. Otherwise, it will damage the multimeter. If you need to shift gears, disconnect the probe first and then measure after shifting gears.
(4) When using a multimeter, it must be placed horizontally to avoid errors. At the same time, it is also important to avoid the influence of external magnetic fields on the multimeter.
(5) After using the multimeter, the conversion switch should be set to the maximum AC voltage setting. If not used for a long time, the battery inside the multimeter should be removed to prevent corrosion of other components inside the meter.
