What is an Oscilloscope Multimeter?

Digital oscilloscopes come from a "rich family" with ancestors dating back to the 1940s. The advent of radar and television required well-performing waveform observation tools, and the analog oscilloscope rose at this time, reaching its peak in the 1970s. Subsequently, the application of high-speed A/D sampling technology and the generation of large-scale integrated circuits have provided sufficient basic space for the design and popularization of digital oscilloscopes. Because the digital oscilloscope can make full use of memory, storage and processing, as well as a variety of triggering and pre-triggering capabilities, the analog oscilloscope has long been difficult to solve the problem of high-speed process, instantaneous process recording and reproduction.

As an innovative application of digital oscilloscope,oscilloscope multimeter can transform the invisible electrical signal into visible image, which is convenient for people to study the change process of various electrical phenomena. Its application range is very wide, involving electronics, power, communication, automotive, medical and other fields, can be real-time acquisition, display and analysis of electronic signals, to help engineers and technicians quickly locate and solve a variety of faults and problems.

So,what is an oscilloscope multimeter? How does it work? What does it do? How do they empower professionals and related fields? How do we choose our instruments?

Oscilloscope Multimeter
Oscilloscope digital multimeter is a new type of handheld digital oscilloscope multimeter which is designed with embedded digital control technology and integrates the functions of digital storage oscilloscope and digital multimeter. Its basic functions include the measurement of current, voltage, resistance and other parameters, which can be used to detect the electrical parameters of various circuits.

Oscilloscope multimeter can not only measure the electrical parameters, but also display the waveform of the electrical signal. Through the display screen of the oscilloscope, the signal in the circuit can be monitored and analyzed, so as to judge whether there is a fault in the circuit. This is also the biggest difference between oscilloscope multimeter and traditional multimeter.

Structure and Principle
Oscilloscope multimeter is an electronic measuring instrument that combines the functions of oscilloscope and multimeter. Its structure and principle combine the characteristics of oscilloscope and multimeter.

In terms of structure, the oscilloscope multimeter usually includes the display screen, control knob, input interface, and internal circuit. The display screen is used to display the measured waveform or value, the control knob is used to adjust the measurement parameters and Settings, the input interface is used to connect the reception test circuit or signal source, and the internal circuit is responsible for signal acquisition, processing, display and other functions.
In terms of principle, the working principle of oscilloscope multimeter is based on electronic measurement technology. For the oscilloscope function, it uses the internal electron beam to depict the waveform of the signal to be measured on the display screen. When the signal to be measured is input to the oscilloscope, the signal is processed by the internal circuit, so that the electron beam is deflected on the display according to the amplitude and frequency of the signal, thus displaying the waveform of the signal. For multimeter function, oscilloscope multimeter can measure voltage, current, resistance and other electrical quantities. Its measuring principle is based on Ohm's law, Kirchhoff's law and other basic electrical principles, sampling and processing the measuring circuit through the internal circuit, and display the measurement results on the display screen.

True RMS value

Multimeter true RMS refers to the actual RMS value of the signal, which can accurately reflect the real power and voltage of various complex signals in the circuit. The opposite is the common RMS value, which is calculatedaccording to the average voltage of the sine wave signal. It is more accurate and practical to reflect the true RMS value of the electric meter accurately for non-sine wave signals.

The characteristics of capacitive reactance and inductance of the circuit. Therefore, for non-sine wave signals, M
In the circuit test, the true RMS value of the multimeter plays a very important role
Yes. In some complex circuits, the waveform of voltage and current may be non-sine wave, the use of ordinary RMS measurement often can not accurately reflect the actual situation in the circuit, but the use of multimeter true RMS can more accurately judge the performance of the circuit and judge whether it meets the requirements.

How to Capture Millisecond Transient Signals

When you need to quickly measure the captured millisecond class transient signal, you can use the maximum/minimum/peak capture function of the CEM High precision oscilloscope digital multimeter DT-9989. The mode captures the intermittent value, the meter can automatically record the reading, there is no need to observe him all the time, the shortest time to record the transient signal is up to 250us, and the data transmission and download can be carried out through PC, Bluetooth function.

Features of Oscilloscope Multimeter

Oscilloscope multimeter has the advantages of high precision and high sensitivity, which can detect small signals and carry out accurate measurement and analysis. At the same time, the display of the oscilloscope has high definition and high contrast, which can clearly display the waveform of the electrical signal and help the user to accurately judge the problem in the circuit.
Can you recommend an easy to use and accurate oscilloscope multimeter, suitable for most measuring occasions?
