Zdravím, chcem sa spýtať, či sa k multimetru dajú dokúpiť aj meracie hroty so systémom svorky, aby sa dali prichytiť na vodiče pre presnejšie meranie. Ďalej sa chcem spýtať ohľadom merania odporu. V niektorých prípadoch píše úplne presné hodnoty (napr. keď som meral odpor fénu pri dvoch nastaveniach výkonu), ale mám problém so žiarovkou, ktorá by mala mať odpor 21 ohmov a ukazuje 2,5 ohmu a samozrejme som skúšal aj svoj odpor, ktorý by mal byť v rozsahu 300 - 900 ohmov a píše mi, že 25 megaohmov. Je to chyba, alebo zle meriam?
