Uma kukhulunywa ngezikali, wonke umuntu ngeke azizwe engajwayelekile. Ziwusizo kakhulu ekulinganiseni isisindo ekuphileni kwansuku zonke. Izinhlobo ezijwayelekile zezikali zifaka isikali sekhishi le-elekthronikhi, izikali zomzimba we-elekthronikhi, nezikali zomzimba ezisebenza ngomshini. Ngakho-ke, yikuphi okuqukethwe okubalulekile okudingeka kuhlolwe futhi yiziphi izivivinyo okudingeka zenziwe lapho kuhlolwa impahla? Sithemba ukuthi lokhu okuqukethwe kuwusizo kuwe!
Isimiso sokusebenza
Lapho into ibekwe esikalini, ingcindezi isetshenziswa inzwa, okuyinto deformed, okubangela ushintsho impedance. Ngesikhathi esifanayo, i-voltage ye-excitation isetshenziselwa ukushintsha nokukhipha isignali yokulingisa yoshintsho. Isiginali ikhuliswa yisekethe yokukhulisa isandiso kanye nokuphumayo kusiguquli se-analog-to-digital. Guqula ube amasignali edijithali asetshenzwe kalula futhi uwakhiphele ku-CPU ukuze alawule ukusebenza. I-CPU ikhipha lo mphumela kusiqapha ngokusekelwe kumiyalo yekhibhodi nezinhlelo. Kuze kube lo mphumela uboniswa.
Ukuhlukaniswa kwezikali
Enqubweni yokuhlola, sisebenzisa kakhulu izikali zasekhishini ze-electronic, izikali zomzimba we-elekthronikhi, nezikali zomzimba eziwumshini
