A detailed explanation of how to measure voltage with a multimeter?
The measurement process of a digital multimeter is converted into a DC voltage signal by a conversion circuit, and then the voltage analog signal is converted into a digital signal by an analog-to-digital (A/D) converter. Then, it is counted by an electronic counter, and finally the measurement result is displayed directly on the display screen in digital form.
The function of measuring voltage, current, and resistance with a multimeter is achieved through the conversion circuit, while the measurement of current and resistance is based on voltage measurement. In other words, a digital multimeter is an extension of a digital DC voltmeter.
The A/D converter of the digital DC voltmeter converts the continuously changing analog voltage into a digital value, which is then counted by an electronic counter to obtain the measurement result. The decoding display circuit then displays the measurement result. The logic control circuit coordinates the operation of the control circuit and completes the entire measurement process in sequence under the action of the clock.
How to measure voltage with a multimeter
1. A multimeter is a commonly used testing tool for us
It is mainly used to test parameters such as voltage, resistance, and current, and plays a significant role in the testing, maintenance, and production of electronic products. The main components of a multimeter are an ammeter, a dial, a range selector switch, and probes. There are many models of multimeters, but the basic usage method is the same. Next, we will introduce the method of measuring power supply with a multimeter and the principle of measuring voltage with a multimeter.
