What is a digital multimeter? What are the advantages of a digital multimeter?

Digital is a convenient tester that integrates the detection of DC voltage, AC voltage, DC current, AC current, and resistance (the pocket type cannot detect current due to safety considerations).

In addition to the above basic detection functions, almost all products have additional detection and on-off buzzer functions.

Launched products that can detect frequency and device capacity.

It has data lock, range lock, maximum value, minimum value lock, relative value detection and other functions.

There are also connectable DMMs (PC series), so that the functions of expensive recorders can be added to the digital multimeter.

Advantages of digital multimeter

1: High-precision detection, with high accuracy (less than 1%) compared with analog pointer multimeter (about 3%);

2: The internal resistance (impedance) is high (the voltage drop between terminals is very low) and there is no detection loss;

3: No reading error. Analog pointer multimeters have visual differences and user reading errors.
