Auto-ranging digital multimeter

The automatic range digital multimeter is more convenient to use. It does not need to select the range manually, which saves the process of range selection. The process of automatic range conversion function is realized by program control hardware, which saves the selection knob, making the measurement process more convenient. Compared with traditional digital multimeters, it improves the test efficiency and the accuracy of test results. The disadvantage is that the low-end model responds slowly. Generally, the automatic range multimeter has a manual selection button. When measuring, you can select manual as needed. For example, when measuring the resistance of a small resistor, it takes a long time to stabilize the reading with the automatic range. At this time, you can press the range selection to set it to the manual gear, and the measurement reading will stabilize quickly.

The differences in the grades of digital multimeters mainly lie in the differences in accuracy, stability, durability, etc. It is recommended to choose high-end imported brands with better strength, and choose domestic brands with slightly weaker strength. The durability of domestic brands needs to be improved.
