The specific methods are as follows:
1, first of all, take out their oscilloscope and use.
2, take out the instrument and connect the power and turn on the device, click the oscilloscope panel above the menu button.
3, you need to use the oscilloscope correctly, use the equipment to test the circuit first cut off the power supply of the high-voltage circuit, and then test.
4, calibrate the instrument, in addition to the correct setup of the oscilloscope, it is recommended to regularly calibrate together on their own, in order to accurately carry out measurements.
5, connect the probe, now we are ready to connect the probe to the oscilloscope, if the oscilloscope is well matched, the probe can ship all the processing power and performance of the oscilloscope to ensure the integrity of the measured signal.
6, connected to the signal, we press the panel of the "autoset" key, the oscilloscope will be automatically set, the square waveform can be stabilized.
