Qhov yuam kev yooj yim ntawm multimeter
Muaj ob txoj hauv kev los qhia qhov yuam kev ntawm ib qho multimeter.
Rau DC thiab AC voltage zog thiab lub zog tam sim no, nws tau qhia raws li feem pua ntawm cov kev txwv sab sauv ntawm qhov ua haujlwm ntawm qhov ntsuas. Cov nplai ntawm cov iav no yog linear lossis ze rau linear; rau hluav taws xob teeb meem, vim hais tias lub teev yog nonlinear, tag nrho arc ntawm lub teev yog siv xwb. Qhov yuam kev yooj yim yog qhia raws li feem pua ntawm qhov ntev.
Qhov kev ua yuam kev yooj yim ntawm cov hluav taws xob tsis zoo uas tau teev tseg hauv phau ntawv qhia multimeter lossis hu xov tooj tsuas yog siv tau rau qhov chaw nruab nrab ntawm qhov ntsuas ohmic (piv txwv li, qhov chaw ohmic), thiab qhov ua yuam kev ntawm lwm qhov ntsuas tau ntau dua li tus nqi no.
Qhov kev ua yuam kev yooj yim ntawm multimeter yog qhia hauv Table 1, thiab tus nqi tshwj xeeb tuaj yeem pom ntawm lub dial ntawm multimeter.
