The computer power switch chip can be measured by the following steps: 1. Use a multimeter or oscilloscope to measure the working state and signal output of the computer power switch chip.
2. The multimeter can measure voltage, current and resistance and other parameters, and the oscilloscope can display the waveform and frequency of the electrical signal.
By measuring the output signal of the power switch chip, you can judge whether it is working normally.
3. When measuring the power switch chip, first determine the pin layout and function of the chip.
According to the chip specification or circuit diagram, find the pin associated with the switch.
Then, using the voltage measurement function of the multimeter, connect one probe to the supply pin of the chip and the other probe to the ground pin to measure whether its output voltage meets the specifications.
If you need to know more about the waveform and frequency of the switching signal, you can use an oscilloscope to measure.
By observing the waveform diagram on the oscilloscope, you can judge whether the switching signal is normal.
It should be noted that when measuring, ensure that the power supply is in a safe state to avoid electric shock or damage to the equipment.
The computer power switch chip can be measured by a multimeter. First set the multimeter to resistance, and then touch the test pen to the two pins of the chip, at which time the multimeter should read infinity.
Next, press the power switch and measure the resistance of the two pins again. At this time, the reading of the multimeter should be zero or close to zero, indicating that the chip has been switched on. If the test results are inconsistent with the above, there may be chip damage or wiring problems that need to be further eliminated.
