Matters needing attention in the use of oscilloscope
Thermal-electronic instruments generally to avoid frequent startup, shutdown, oscilloscope is the same
If the waveform is found to be affected by external interference, the oscilloscope housing can be grounded.
Turn the brightness adjustment knob counterclockwise to the bottom to minimize the brightness, and then disconnect the power switch.
When observing the bright spot on the screen and adjusting it, the brightness of the bright spot should be moderate, not too bright
The voltage of "Y input" should not be too high, so as not to damage the instrument and not to exceed 400 V during the maximum attenuation. When the "Y input" wire is suspended, there will be interference waveform caused by external electromagnetic interference, which should be avoided
We know that although there are several categories of oscilloscopes, the models are different, but in addition to the width of the frequency band and input sensitive fu are not completely the same, its use method is basically the same.
