High voltage measurement testing are not allowed over 300 volts
Even when you can read in a probe 600V PK CAT I. The Aktakom, Owon or Rigol oscilloscopes does not support more than 300V RMS or 400V PK. For higher voltage please contact us to request a special device.
The measured voltage amplitude value is 10 times greater or smaller than the actual value
Check whether the channel attenuation coefficient and the attenuation coefficient of the probe used is match. Up
When changing the horizontal sweep on the digital oscilloscope at different horizontal points observed inexplicable change in the form of the same signal, why is this happening?
In fact, this is not a problem.
Just keep in mind that you're using a digital oscilloscope, which digitizes the signal with different sampling rates depending on the selected horizontal sweep, and then connects the digitized points with strait line while restoring the real shape of the signal.
Your first screen shows that you are measuring voltage 50 Hz with the 10 ms / div sweep and a sampling frequency of 20 kHz Ks/s
One signal period (20 ms), digitized in this mode, 20E-03 (sec) * 20E03 (1/sec) = 400 points. This is enough to properly restore and interpolate a sine wave of 50 Hz (i.e. in a period of 20 ms).
Normal display, with a sweep 10 ms / div:
Distortion of the same signal at 10 s / div sweep
Your second screen is set to sweep 10 sec / div, and sample rate on a sweep turned to 20 samples per second (20 Sa / s). I.e. one signal period 20 ms had: 20E-03 (sec) * 20 (1/sec) = 0.4 points. That means that to restore (to interpolate the points) a sine wave with less than one point in time is impossible, so you get this mess (known as "aliasing" or a false frequency) formed by the beats of the measured frequency and sampling frequency.
In order to correctly install a data collection in a digital oscilloscope one should follow a simple rule - the sampling rate must be at least 5-10 times higher than the frequency signal, in that case you will not have the issues that we just discussed.
This applies to all digital oscilloscopes and in no way connected to any particular make or model of oscilloscope or its probes.
There is wave form displayed, but it is not stable
Check whether the Source item in the TRIG MODE menu is in conformity with the signal channel used in the practical application.
Check on the trigger Type item: The common signal chooses the Edge trigger mode for Type and the video signal the Video. Only if a proper trigger mode is applied, the wave form can be displayed steadily.
Try to change the trigger coupling into the high frequency suppress and the low frequency suppress to smooth the high frequency or low frequency noise triggered by the interference.
