As a universalus ir nešiojamas instrumentas, a multimetras can measure a wide range of physical quantities, such as AC/DC current, AC/DC voltage, resistance, talpa, inductance, and audio level. Multimeters can generally be divided into two types: analog pointer multimeter and digital multimeter. From my experience using a multimeter, I can see that using a pointer multimeter is sufficient when measurement and checking circuits in a circuit. For example, when check the three pins and tube type of a transistor that is unknown in its model during work, I believe that a pointer multimeter is useful; When the measurement circuit needs to be specific to digitical values and when reading measurement data, it is more tinkama to use a digital multimeter.
Aš tikiu kad pasirinkimas a multimetras turėtų būti pagrįsta on the nature and requirements of our job. If we are engaged in the general electronic and electric industry or its enthusiasts, I believe that a typical multimeter can be competent for our job.

The first point I think when choosing a pointer multimeter, the first thing to consider is the quality. A high-quality multimeter usually will not have any problems after three to five years of use. If the quality is poor, it will cause the pen to break after three to five months of use. For heavy cases, small faults such as inability to zero the ohm or poor contact will continue, making it very annoying to use. When choosing a pointer multimeter, in addition to having the merchant measure some simple physical quantities, I also need to weigh it in my hand. A high-quality multimeter feels "heavy" in my hand, while a low-quality pointer multimeter feels light and smooth in my hand, which can also be reflected in the workmanship and materials used.
The second point is to buy some brands of pointer multimeter, because a good brand is the guarantee of quality. For example, MF-47 series pointer multimeter, MF500 type multimeter, etc. are all available for selection. The multimeter I use in my daily work is the MF470 pointer type multimeter, which has been in use for many years and is still in use.
There is still a lot of room for selection for digital multimeters, such as those from brands such as Unilever, Fluke, and Victory. I paprastai use Unilever, and if there are no special requirements, it can generally meet my work needs.
Po pirkimo a multimetras, mes taip pat reikia mokėti dėmesio į reguliarų priežiūrą ir turi a taisyti naudoti metodas. Nors mes turime nusipirkome a gerai multimetras, jei mes negalime išlaikyti it arba naudoti netinkamai, it bus sumažinti the service life of the instrument and even damage the multimeter.
