When buying a multimeter, you must consider four points
A multimeter is a multifunctional product that is also easy to carry and is used for measuring various resistors, voltages, and currents. It is also a commonly used product by electrical maintenance workers. Due to its multifunctional advantages, it is also known as a multimeter or reusable table.
When purchasing a multimeter, it is important to consider the following points:
(1) Display mode
Digital multimeters are suitable for situations with relatively high measurement requirements; Analog multimeters are suitable for measuring situations with general requirements; There is now a dual display multimeter that combines analog and digital functions, suitable for testing situations with rich content. With the improvement of the measurement function and cost-effectiveness of digital multimeters, the use of pointer multimeters will become increasingly rare.
(2) Basic measurement
Basic measurement is a necessary range for a general multimeter, such as DC current, voltage range, AC voltage range, and resistance range. When necessary, consideration should be given to whether AC current measurement is necessary.
(3) Additional Range
Appropriately considering additional measurement ranges can bring many conveniences to daily maintenance, such as capacitor mode (some digital multimeters have a capacitance range of up to 2000), transistor static coefficient measurement mode, first gear testing mode, diode (DT) measurement mode, etc.
