Multimeter function is not working
Hello. I have a ZT-703S with a problem: the oscilloscope function works fine, all buttons work, and it takes measurements normally. However, when I switch to the multimeter function, only a few windows appear, including the analog scale, but no numbers appear. It no longer responds to functions like diode, resistance, and voltage. I updated the firmware and reset the settings to factory settings, but it still hasn't returned to normal. Does anyone know how to fix this?

Hi @brunogouve48763
had you checked the internal fuse?

Yes, I checked the fuses, they are ok. I haven't found the solution yet.

Isn't the issue in below Youtube video a similar issue as what you have?

He was a able to fix it by re-soldering the chip.

Hello!
Yes, the same problem as in the video.
However, I resoldered the component as instructed in the video, and it didn't work. When measuring with an oscilloscope, there are frequencies in the transformer's primary and secondary. But it still doesn't work.
