What are the advantages and disadvantages of digital multimeter and analog multimeter
The difference between a digital multimeter and an analog multimeter
Comparing the advantages and disadvantages of digital multimeters and analog multimeters is to see what are the differences between the two. Here are four main points.
1. The internal power supply is different, the digital only needs a 9V laminated battery, and the pointer also needs a 1.5V No. 2 battery;
2. The gears measured by numbers and pointers are different;
3. The digital measurement accuracy is higher than that of the pointer, and the measurement of DC voltage should not be divided into positive and negative poles and intuitive reading;
4. Numbers and pointers add many functions to the gears.
The polarity of the battery connected inside the multimeter is different: the digital positive test lead is connected to the positive black test lead of the battery, and the pointer is opposite. Diodes measured by a digital meter exactly match the actual polarity of the diode, whereas an analog multimeter is the opposite.
