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

[Spirex]

What is the capacity of the battery, who measured?

[matefon]

Didn't measure, but this is the label:

[Spirex]

Measured the actual battery capacity, 2750 mA/h, resistance 79 mΩ.

[Astur_TorQue]

How do you measure?

I just loaded Firmware 1.4.2 and now it completely ignores the Auto Off setting and just turns off after a few minutes

Have companies forgotten about regression testing? Seems ZOYI, or the contractors they have programming the device fix or enhance one thing, and break something else with regularity. Some of you should offer up your services as regression testers. I wrote this before: this product could be really great, but some entity needs to take control of their SW development, test and validation processes.

It definitely turns off, maybe the backlight turns off after 120 seconds? which is turned on in the menu in oscilloscope mode.

I know it's doing my head in, every few minutes I have to turn the damn thing back on, I mentioned it to a chap who I think works at Zoyi, on one of his Youtube vids, I dodn't know if he will take any notice of me.

reset the device.  set the black screen setting to 0.  or off I don't remember.  and automatic shutdown.  turn it off.  two separate settings.

I also have firmware 1.4.2 loaded and I don't see any problems with the unit auto shutting off.
There are 2 settings in the menu:
AutoOff and BLtime
Set AutoOff - OFF and BLTime - OFF and check if the unit turns off with these settings?
If I set AutoOff - 1min, then exactly after 1 minute the device signals "AutomaticShutdown" on the display and turns off.

[wedgehog]

Black screen setting? where's that, I will gladly try it mate

BLTime 
 suddenly I couldn't remember what it was called.  I write with Google Translate from my phone at work.

[wedgehog]

No problem mate, but where is it? all I can see is Backlight in percentages and it just turns the brightness up and down, are we talking Multi-meter menu's or scope menu's?

[wedgehog]

Ok, I found it, in the scope meu's, I have set them both to off and have it beside me will wait and see, thanks guys

[wedgehog]

Looks like that's got it, Thanks  Guys, this is why I love forums 

[xfint34]

It would make more sense if the setting for backlight time was next to backlight brightness.

[apollo11fan]

OK, good it's not broken. Just a usability design issue. Yeah, that is the sort of thing that can also benefit from some expertise in user interface design to make our interactions with the device more obvious and natural.

Trigger in version 1.4.2 does not work with time scale 250ns/div and less. So I can't observe 100-200-400ns pulses in good resolution.
It worked fine before... Amazing device...

I can't confirm your conclusions. On my device with version 1.4.2, the trigger works normally over the entire duration range.
Show your video of the malfunction?

Yes, the trigger does not work correctly in these modes. The pulse is displayed, but outside the screen. You have to search with the MOVE button.

I checked all firmware versions, the trigger works correctly only version 1.3.8

Give one pulse 1-10 uS. And you won't see him. He will be behind the screen.

Yes, now I see the poor performance of the trigger. On version 1.3.8, the trigger operation is more reliable, so for now we will remain on this version.

Where do you get old versions?
