    hi. i am facing issue with metrasafe-20 , it is showing wrong voltages while i measure 7805 positive voltage regulator with variable load.
    Can anyone let me know the reason of variable voltage at the o/p of 7805

      May be the load consumes more current that why

      Check resistance and diode near voltage line and also white capacitor (low capacitance) usually these caps are in nano farad range or even pico farad near main ic on different multimeters. If these caps go bad they can give infinite beep sound, fading display (or ghosting), and blinking numbers
