I have a 220 - 14 V transformer, but when I hook it up to oscilloscope or DMM they show different values. DMM shows 11.8V and oscilloscope shows 17.2.
Ok, this is cheap Chinese transformer, so it can possibly be not accurate, but what the hell with readings? I know my equipment kinda low-class and low-accuracy, but how can it have such a big difference? What is the reason and what reading is more accurate?
