There are several ways to test a DC power supply, and here we present only a few common methods.
Conductivity Test: You can use the multimeter's conductivity mode to accomplish this test. Touch the positive and negative terminals of the power supply with the multimeter pens. If it is on, the multimeter will beep. This test is designed to determine if the power supply is energizing and if there are any breaks in the wiring.
Voltage Test: You can use the DC voltage mode of your multimeter to accomplish this test. Touch the positive and negative terminals of the power supply with the multimeter pens. The multimeter should display the voltage output from the power supply. Compare this voltage to the rated voltage of the power supply to make sure it is in the correct range.
Load Test: You can connect a load (such as a light bulb or motor) to the power supply and measure the voltage and current with a multimeter. The voltage should be stable and within the expected range; the current should be within the rated current of the power supply.
Ripple Test: You can measure the AC component of the power supply output voltage. Connect an oscilloscope to the output terminals of the power supply and measure the voltage ripple. The ripple voltage should be as low as possible and within acceptable limits.
Always test the power supply with care as specified in the operation manual and safety guidelines. If you are unfamiliar with electronic testing, it is best to consult a professional or use pre-constructed test equipment.

View Full VersionAn oscilloscope captures and displays signals in the time domain, while a spectrum analyzer captures and displays signals in the frequency domain. Sometimes, oscilloscopes have a built-in spectrum analyzer function to make it easy to analyze signals in both the time and frequency domains. ,
View Full VersionThe Function Generator provides a preset list of waveforms or code patterns that it can generate. In a function generator, the user can change waveform parameters such as frequency, amplitude, and offset, as well as add simple distortion. Arbitrary waveform generators are more complex and can emulate real-world signals. Arbitrary waveform generators utilize pre-stored digital data to generate these waveforms,...
View Full VersionWondering about resistance measurement methods! In this article, we will cover basic resistance measurements and precautions. Resistance is very important in electronic device circuits. If the resistance is not appropriate, it can lead to malfunctions and other problems. However, electricity is not visible. To find out if the resistance in a circuit is appropriate, you need to use a specialized measuring instrument. To measure resistance, you need to use a measuring instrument...
