New Zoyi multimeter+oscilloscopes - ZT-70xS, up to 50MHz/250MSps (nov 2022)

Any manual how to use osciloscopes? I bought this but I don't know anything about oscilos hehehe

BTW with 1.3.9 the signal generator doesnt work well

There are countless tutorials on the web and videos on Youtube.  The forum owner himself has made many oscilloscope tutorials.  This one is an Introduction.


If you'd rather read something, this is the first one coming up in a search.  It looks pretty good.

press the "MENU" button, navigate with the arrows to where "BL time" is, switch it to off.
There is an "Auto Off" which turns off the device after the set time.

Any file manager. That's all.
You can only retrieve saved screenshots or update the firmware via USB.
Even the multimeter readings must be read via the signal generator contacts. This will require a simple UART module with TTL levels.

Any developement for "MORE APPS"? hehehehe

I hope not.
They should focus to the basic functions first, to get them working properly.
For example the "autoset" on the oscilloscope is useless, because it is so slow and unreliable.

Hello. Recently purchased a ZT-703S. I've upgraded to firmware V1.3.9. Is anyone else experiencing problems with the signal generator. Everything seems to be a square wave.
Also, is there an updated manual that has kept up with the revisions of the Firmware? Thanks.
