I've tried again but no luck.. Guess I've to wait for an official release.
my scope with v1.2.9C i bought this month and I'm able to enter zoom mode., maybe i got a more developed firmware, but the zoom feature and continuous auto are not documented I think you will need an update to 1.3.0C it's not available yet because they are still working on it. The zoom feature is a new implementation they are trying to add to the scope, it has some bugs needed to be fixed, at the moment zoom work fine at frequencies of 1MHz and above, bellow 500KHz that not so good. Like I said before in Zoom, I'm able to freeze crash the scope in more than one way, I'm doing videos and cooperate with them so that the firmware become stable and we all could benefit from a better scope and the best of the moment in this category/price. Zeeweii won't forget their customers and that's nice to know, they really believe in their products and I'm not in anyway affiliated with them, just when i believe a product has potential to be a good device i cooperate and this one has. They try to release the device in the most stable condition, unlike fnirsi for ex. In the case of fnirsi they're loosing because of that, bad implemented features, cursors is one of them, look like they created something in a rush. I could buy one if they solve at least this important feature, until then no way.
for those interested, they are planning to release a new device in a month or so, its a multimeter+scope combination, model dso3D12, the user manual is ready to download from ZEEWEII website. I attached the user manual, you can downloaded here or from ZEEWEII website, it's up to you.
