Njengamanje, izimoto eziningi zifakwe izinzwa zangaphakathi ukuze zihlole ingcindezi yokusebenza yangaphakathi yesondo.Umfutho wesondo uzoboniswa ngokushesha etafuleni lezinsimbi, noma ungalinganiswa ngokunembile imitha yokucindezela isondo, engahlukaniswa ngamamitha okucindezela isondo lekhampasi, amamitha okucindezela amathayi okuboniswa kwedijithali kanye namamitha okucindezela isondo le-alamu.I-digital tire gauge iphinde ikhombise umfutho wesondo ngesikhathi esifanayo, kuyilapho i-alamu ye-alamu isebenza kuphela uma umfutho wesondo uphezulu kakhulu noma uphansi kakhulu.
Ikhampasi isondo ingcindezi gauge, kuyadingeka ukulayisha ukudayela wathi ukufunda value ukuqonda ingcindezi isondo, ngokuvamile ihlukaniswe yaba indandatho yangaphakathi nangaphandle, ngaphandle iyunithi British psi, ibhizinisi indandatho yangaphakathi kg/cm^2 , izibalo zabo phakathi kuka-14.5psi=1.02kg/cm2=1bar.Ngokuvamile bheka iringi yangaphakathi, ngoba isilinganiso esincane seringi yangaphakathi singu-0.1, isikali esincane sangaphandle singu-1, futhi iringi yangaphakathi inembe kakhulu.
Uma umfutho wesondo uphezulu kakhulu kudeshibhodi, ngokuvamile ingaphezulu kuka-345kpa i-alamu yengcindezi ephezulu kancane kancane, isondo kufanele licishwe umoya ukuze lilungise cishe u-335kpa ukuze kuqedwe le alamu yomfutho ophezulu olandelayo: Uma ingcindezi yesondo iphansi kakhulu, ngokuvamile ingaphansi kuka-175kpa kancane kancane. i-alamu ye-voltage ephansi, kufanele ilungiswe ifike ku-230kpa ngaphezulu ukuze kuqedwe i-alamu ye-voltage ephansi.Uma i-alamu yokukhishwa kwengcindezi yesondo esheshayo kwenzeka, okubonisa ukuthi ukucindezela kwesondo kuncishisiwe ngaphezu kwe-30kpa ngomzuzu owodwa, khona-ke uhlu lwezinkinga kufanele lwenziwe, futhi i-alamu izoqedwa kuphela lapho imoto yonke icishiwe.
Uma lungekho uhlelo lokubona umfutho wesondo noma isikali somfutho wesondo, ungalinganisa umfutho ojwayelekile wesondo, okungukuthi, qaphela ngokucophelela izinga lokuguquguquka kwesondo ukuze uhlukanise umfutho ojwayelekile wesondo.Kunezindlela ezimbili zokulinganisa umfutho ojwayelekile wesondo, eyokuqala iwukuthi imoto ibishayelwa emgwaqeni wesihlabathi, bheka ibanga eliphakathi konqenqema lwesihlabathi kanye nehlombe lesondo, uma unqenqema lungena nje. ihlombe lesondo, noma eduze kwehlombe lesondo, ukucindezela kwesondo kulungile.
Uma unqenqema lwendawo ethintekayo lukude nehlombe lesondo, ukucindezela kwesondo kuphezulu kakhulu, okuzokwenza ukuthi isondo libambe umhlaba futhi linciphise ukuthembeka;Uma uhlangothi oluhlangothini lwendawo ethintekayo luphendulelwa phezu kwehlombe, kubonisa ukuthi umfutho wesondo uphansi, ukusetshenziswa kukaphethiloli kuzoba kukhulu, ukushisa kuzobe kubi nakakhulu, futhi isondo eliphansi le-voltage lizoholela kalula ekuphepheni kwesondo.
Okwesibili ukubuka ngokucophelela inani eliphelele lamaphethini endaweni yesondo ukuhlukanisa ukucindezela kwesondo.Uhlamvu phakathi kwezikhala ezimbili.Uma wonke umfutho wesondo ujwayelekile, inani eliphelele lezimpawu zomgwaqo amathayi zingu-4 kuya ku-5, ezingaphezu kweziyisihlanu zibonisa ukuthi umfutho wesondo uphansi kancane, ngaphansi kwezine kubonisa ukuthi umfutho wesondo uphezulu kakhulu.
