How to use the multimeter
The multimeter can not only be used to measure the resistance of the measured object, but also the DC voltage can also measure the DC voltage.Some multimeter can also measure the main parameters of the transistor and capacitor capacitors.The method of full mastery of the multimeter is one of the most basic skills of electronic technology.So, how to use the multimeter? What should I pay attention to when using a multimeter? Lets take a look with the editor! China
1. Before using a multimeter, "mechanical zero" should be performed, that is, when the electricity measurement is not measured, the universal meter pointer refers to the position of zero voltage or zero current.
2. In the process of using a multimeter, you cannot contact the metal part of the table pen with your hands. On the one hand, you can ensure the accuracy of the measurement, and on the other hand, it can also ensure human safety.
3. When measuring a certain power, you cannot change the gear while measuring, especially when measuring high voltage or large current, you should pay more attention.Otherwise, the multimeter will destroy.If you need to change your shift, you should first disconnect and measure it after shifting.
4. When using the universal meter, it must be placed horizontally to avoid errors.At the same time, it is also necessary to notice the impact of external magnetic fields on universal meters.
5. After the use of the multimeter is used, the conversion switch should be placed at the maximum transmission of the AC voltage.If it is not used for a long time, the battery inside the multimeter should also be taken out to prevent other devices in the battery corrosion.
