A słuchaj, nie przechowywałeś go w jakichś wilgotnych warunkach? Albo w zimnie? Może wpierw zaaklimatyzuj miernik. Właśnie nie! Przechowywany był w normalnych warunkach pokojowych. Mało tego jak by się błąd pomiaru powiększał! Bo jak mierze +5V to już 8,2V pokazuje!! edit napisałem e-mail do firmy UNI-T w Hong Kong. Opisałem swój problem i jakiś miły gość odesłał mi instrukcje kalibracji miernika!! :D Ale, albo ja jakiś tępy jestem albo w tym XLS nie jest instrukcja kalibracji (mimo że tak w niej pisze). Bo jakoś nie mogę się doszukać czynności, które kalibrują wskazania. Nie wiem czy dobrze zrozumiałem, ale piszą tam coś o jakimś programie w którym zmianie się wskazania......:?: Może ktoś bardziej znający angielki pomoże?:?:
