HANTEK 6254BD calibration does not finish

Berni

Hi,

I have a quite new HANTEK 6254BD USB oscilloscope. I was testing the accompanied software a lot and it seems that I stopped the calibration in progress.

Now I have no chance to calibrate channel 1. For channels 2 to 4, it tries to find min. and max. values for the different ranges. For channel 1, the signal is jumping up and down and never gets stable. Therefore, I assume, the process cannot resume since the software is waiting for a stable signal.

I tried to factory reset it, switched it on/off, .. still no chance. Now I cannot use channel 1 at all!

How can I set the calibration to default? It there another way to "hard reset" it?

thanks,
Berni

thanks for the link. I measured the test point voltages and these seem fine.

meanwhile I could solve the problem by cancelling the calibration at some point. This somehow recovered the - obvisously bad - calibration factors from the cancelled calibration before.

So I can confirm:

1. it's purely software related
2. Load factory defaults does NOT reset the calibration factors (but it should)
3. The calibration factors are not reset prior a new calibration attempt. So if they are invalid (for any reason), you cannot calibrate the device or a single channel anymore!

I think all these issues can be solved by the Hantek 6000 Windows software. An update / bug fix would be appreciated!

I was trying the most recent one (2.3 ?) and also 2.2.6. Same issues.

It seems once the calibration factors are corrupt, they are not reset to default prior calibration.

In my case, cancelling the calibration at a certain point somehow fixed it by incident!
