Components are an indispensable part of electronic products, and the identification and measurement of components are essential work for electronic engineers and researchers in the development and manufacture of electronic products. This article will introduce the identification of components and the use of measuring instruments.

1、 Identification of components

The identification of components is an important task in the development and manufacturing process of electronic products, mainly including the following aspects:

1.Appearance identificationIdentify the type and brand of components by observing their appearance, color, logo, and other characteristics.

2.IdentificationIdentify specific parameters and performance information of components by searching for identification information on them, such as model, specification, production date, etc.

3.Measurement identificationBy using measuring instruments to measure components, such as resistance measurement, capacitance measurement, inductance measurement, etc., identify specific parameters and performance information of the components.

At the same time, it is necessary to combine the circuit diagram and the specification manual of the components to check whether the components meet the requirements in the specification manual, such as voltage, current, resistance, capacitance, inductance, and other parameters.

2、 Use of measuring instruments

MultimeterA multimeter is a basic measuring instrument that can be used to measure circuit parameters such as resistance, capacitance, inductance, voltage, and current.

The usage method is as follows:

Confirm instrument gear: Select an appropriate gear based on the parameters of the circuit being tested.

Connecting circuit: Connect components such as resistors, capacitors, inductors, etc. to a multimeter, paying attention to the positive and negative poles when connecting.

Measurement data: judge whether the parameters of components are normal according to the values displayed by the instrument.

oscilloscopeOscilloscope can be used to measure parameters such as voltage, current, frequency, etc. of a circuit.

The usage method is as follows:

Confirm instrument settings: Set the measurement mode and parameters of the oscilloscope based on the parameters of the circuit being tested.

Connecting circuit: Connect the components to the oscilloscope, paying attention to the positive and negative poles when connecting.

Measurement data: judge whether the parameters of components are normal by observing the waveform on the oscilloscope screen.

Field strength meterA field strength meter can be used to measure the strength of electric and magnetic fields.

The usage method is as follows:

Confirm instrument settings: Set the measurement mode and parameters of the field strength meter based on the parameters of the circuit being tested.

Connecting circuit: Connect the components to the field strength meter, paying attention to the positive and negative poles when connecting.

Measurement data: judge whether the parameters of components are normal by observing the values on the screen of the field strength meter.

Spectrum analyzer: The Spectrum analyzer can be used to measure the frequency response of the circuit.

The usage method is as follows:

Confirm the instrument setting: set the measurement mode and parameters of the Spectrum analyzer according to the parameters of the circuit being measured.

Connecting circuit: connect the components with the Spectrum analyzer, and pay attention to the positive and negative poles when connecting.

Measurement data: judge whether the parameters of components are normal by observing the spectrum diagram on the Spectrum analyzer screen.
