ANENG goes crazy with new meters

That's a FAIL - the MOV's and PTC are on the wrong side of the board! So the PCB trace seeing HV has a long trip across the board and surely arcs to something else.
This is why we TEST the boards to 61010, to catch these mistakes.
It's too bad their PCB designer does not understand high voltage design, and they are the only person in china doing the layout on all of these multimeters. They all have the same mistakes over and over and over.

Ha-ha, for a moment I thought you meant they should have been mounted on the bottom side of pcb  :-DD

Yeah I was meaning left vs right. You can flip it and look at the other side (LCD, rotary switch) and I'll bet it's a disaster following the input jack trace over to the MOV/PTC/MELF's. Could not find board pics of that.
If only they could reverse-engineer a Fluke or Brymen, minus the dyslexia. They should try some real 61010 testing to educate their PCB layout guy.

ZT-Y2 has the extra 4-digit (temperature&freq) display compared to ZT-Y, so I would expect poorer contrast even though it's 3xAAA 4.5V power. The bar graph is grouped so around 20 segments looking like 100 lol. Another waste of mux ratio. More more more but less less less performance.
I'd rather have less information on the LCD and greater contrast. How useful is staring at "0020"? Oh and I know my line frequency DUH.

Not really a clone, I think. It looks like it's the same meter, manufactured at the same factory and branded individually for whoever is willing to pay for their branding.

Zoyi are the OEM for these meters. Everybody else is the rebrander.

I wrote about it. Only I don’t understand why there is no ZT-225 multimeter on the official ZOTEK website?
