Electronic measuring instrument is a kind of commonly used measuring instrument which has certain application in many industries. There are many types of electronic measuring instrument. There are oscilloscopes, signal generators, multi-meters, etc. These are all electronic measuring instruments. What kinds of electronic measuring instruments do users have?

Multimeter

Analog voltmeters, analog multimeters (ie, pointer multimeter VOMs), digital voltmeters, and digital multimeters (ie, digital multimeter DMMs) are all examples of this. This is a frequently used instrument. It can be used to measure AC/DC voltage, AC/DC current, resistance, capacitor capacity, inductance, audio level, frequency, transistor NPN or PNP current amplification β value.

Oscilloscope

An oscilloscope is an electronic instrument that measures voltage waveforms. It can graphically display the regularity of the measured voltage signal over time. The use of an oscilloscope can not only visually and visually observe the changes in the measured physical quantity, but also can be used to compare the frequency and phase with the waveforms it displays, measure the voltage and current, and trace the characteristics.

3. Signal generator

Signal generators (including function generators) provide signal sources for troubleshooting and debugging electronic equipment and instruments. It is an oscillator that produces a certain waveform, frequency, and amplitude. For example: Generate sine wave, square wave, triangle wave, ramp wave and rectangular pulse wave.

Transistor characteristics display instrument

Transistor characteristic plotter is a special oscilloscope, which can directly observe various transistor characteristic curves and curvature clusters. For example, the input and output characteristics and feedback characteristics of the three types of transistor common-emitter, common-base and common-collector methods; the forward and reverse characteristics of the diode; the voltage regulator or Zener characteristics of the Zener transistor; it can measure transistor strikes. Wear voltage, saturation current, auto or a parameter, etc. 5. Megohmmeter

Megohmmeter (commonly known as the shake table) is a kind of simple direct-reading instrument that inspects electrical equipment and measures high resistance. It is usually used to measure the insulation resistance of circuits, motor windings, and cables. Most of the megohmmeters are powered by hand-cranked generators, so they are called oscillating watches. Since its scale is in Megaohms (MΩ), it is called a Megohmmeter.

6. Multi-channel temperature recorder

Multi-channel temperature recorders, including multi-channel temperature tests, have the ability to store and connect PCs, analyze data by software, and more.

7. Integrated circuit tester

This kind of instrument can test the functions and parameters of TI1, PM0S, and CM0S digital integrated circuits. It can also determine the chip type of the erased word and the on-line functional test and online status test of the integrated circuit.

8.LCR parameter tester

Inductance, capacitance, and resistance parameter measuring instruments not only automatically determine the nature of the element, but also display the symbolic pattern and display its value. It can also measure Q, D, Z, Lp, Ls, Cp, Cs, Kp, Ks and other parameters, and show the equivalent circuit pattern.

9. Spectrum Analyzer

Spectrum analyzer has a wide range of applications in frequency domain signal analysis, testing, research, and maintenance. It can measure the amplitude and frequency of the signal at the same time, test and compare the composition of multiple signals and analysis signals. You can also test the phone logic and RF circuit signals. For example: control signals of a logic circuit, baseband signals, local oscillator signals of an RF circuit, intermediate frequency signals, transmission signals, and the like.

In addition to the above commonly used electronic measuring instruments, there are time measuring instruments, bridges, phase meters, dynamic analyzers, optical measuring instruments, strain gauges, flow meters, and the like.
