Why nobody Help me...?????

amy

Sir,
About the trigger problem, please give me the actual parameter of your waveform. The best give me a picture of the real waveform

amy

Sir, please chenge the trigger sweep to normal to test and give me a video to study.
About the noise, in your trigger video I don't see the noise. Are you sure not any of the signals connect to CH1?

amy

First of all, for triggering problems, please change the trigger mode to normal, and then send us video to study.

About the measurement of the current in your video, CH2 has measured the current value of 50.2A in the following picture.
The value become 3.14A later. The signal has been lost.
   

The DC gain accuracy is 3%*full range. You set the volt/div to 100A. The deviation is correct between ±24V.
Even if you don't input the signal, there may be the deviation.

In your another video: https://www.youtube.com/watch?v=lblcbQzKcbc
Your signal is intermittent. The measurement results are updated in real time
And when you change the vertical scale, the waveform can't be display fully.
In the following picture, the vertical scale is 200mA, the full range is only 1.6A. The maximum current of CH2 signal is 1.47A. It is correct.

What happaning  here it behaves wired and freeze  http://www.fastswf.com/BaUh27Q

Sir, you didn't give me the video I wanted about the trigger. I can't help you.

About the deviation error, Would you please confirm the oscilloscope or the current clamp?

The software freeze: I don't know how you operate it, and then it crashes.
I don't just need results. I also need how to crash.

Please refer to the picture to change the length.




PS: Can you describe clearly one by one? Did you see my reply?

Here is requested trigger video  http://www.fastswf.com/c56dSXw

Sir, about the trigger, it is not a bug.
I think there is a short pulse in your signal.
This pulse signal has been detected when triggered. You can view the "Trig'D" on the top left corner of the software. It explains the success of the trigger. And the frequency of triggering is very high.
But the sampling is very low when the tiembase is 20ms. The short pulse has not been collected.

Example, this is the signal I draw in the following picture. There are four short pulses.


Use the DSO6000, edge and auto trigger in the following video. Each trigger was successful. But not every pulse is collected.


In addition, You can use the peak detect to acquire the short pulse.


If you don't want to colloect the short pulse and only want to trigger your main waveform, you can set the trigger mode to pulse and the trigger sweep to normal, and set the pulse width.


For example in this vidoe.

When nothing is connected i see this..?

If it is the noise from the scope, please contact your seller to return factory for repair.

The buffer length only can be set as 4K if you want to record the data.

deviation error 314mV i see it when nothing connected...

I don't know how you operate it before the device crash.

About trigger..

This is a scope for car repair right....? It was low frequency signal and it was ju ...

Sir, this product is not hardware trigger, it is software trigger.
But on the top left corner of the software, always displays "trig'd", it means it is triggered.

Use my method, maybe you can view the short pulse.
You can't see it, it doesn't mean it doesn't exist.

About the noise, you can contact your seller on aliexpress. He will deal with it.
