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

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

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

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

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.

I does not crash i can click unclick buttons, menus,radio buttons..it just wont execute intended actions it supposed to do...? See the video carefully..

Thanks..

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.

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.

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 just Car engine coil firing at idle ...

its seems this scope does not have better edge triggering hardware built in this scope... there is also  tick tick tick noise coming from inside the scope..(this is not a concern for me but the unusable trigger is)

Becasue of  random 314mV noise how do i replace my scope..? i have brought it few week ago from aliexpress.. my serial is 641004141

Thanks..

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.

Which Hantek Scopes have better Software and Hardware trigger...?
