Hi! Sorry I am asking a very basic question, but I couldn’t figure out how to change vertical and horizontal scales on my DS203. Versions:
- Hardware Ver V2.70 Serial No:7BE6A482
- DS203 Mini DSO SYS Ver 1.52
- DS203 Mini DSO APP (PLUS A1) Ver 1.06
The 1st line shows “RUN” “DC” “DC” “CH©” “CH(D)”…
I set the right navigator so the 2nd item blinks.
With the left navigator I choose it to be “DC”, “AC” or “–”.
But the 2nd line says “2V” and I found NO way to access this line after hours of fiddling with all the controls and downloading several PDFs on how to use this instrument.
Just FYI, I am an electronics engineer since 30 years ago, I perfectly know every function of my old delayed-sweep TRC scope, but this Quad is getting out of my nerves.
I have the impression the firmware is corrupt. Do you suggest downloading a new or same version, or taking some other steps?
