Please don't use that meter for hazardous voltages i.e. anything above 60VDC or 30VAC! It's not safe.
The 10A current measurement is also unfused. Don't use it on anything not powered from a current limited power supply small battery (i.e. AA cells), otherwise it can catch fire if overloaded.
Really that multimeter is a turd. Ideally it should be replaced with a decent one, long term.
