Yintoni uNyamezelo lweCalibration kwaye ndilubala njani?

Ulungelelwanisoukunyamezelana kuchazwa yi-International Society of Automation (ISA) “njengokutenxa okuvumelekileyo kwixabiso elichaziweyo; inokubonakaliswa ngeeyunithi zomlinganiselo, ipesenti yobude bexesha, okanye ipesenti yokufunda.” Xa kuziwa kumlinganiselo wesikali, ukunyamezela sisixa sobunzima bokufunda kwisikali sakho kunokwahluka kwixabiso legama lomgangatho wobunzima obuchaneke ngokupheleleyo. Ngokuqinisekileyo, yonke into iya kuhambelana ngokugqibeleleyo. Kuba akunjalo, izikhokelo zokunyamezelana ziqinisekisa ukuba isikali sakho silinganisa iintsimbi ngaphakathi koluhlu olungayi kuchaphazela kakubi ishishini lakho.

 

Ngelixa i-ISA ichaza ngokuthe ngqo ukuba unyamezelo lunokuba kwiiyunithi zomlinganiselo, ipesenti yesithuba okanye ipesenti yokufunda, kulungele ukubala iiyunithi zomlinganiselo. Ukuphelisa imfuneko yayo nayiphi na ipesenti yokubala ilungile, njengoko ezo zibalo zongezelelweyo zishiya indawo enkulu yempazamo.

Umvelisi uya kuchaza ukuchaneka kunye nokunyamezela isikali sakho esithile, kodwa akufanele usebenzise oku njengokuphela komthombo wakho ukumisela unyamezelo lokulinganisa oza kulisebenzisa. Endaweni yoko, ukongeza kunyamezelo oluchaziweyo lomenzi, kufuneka uqwalasele:

Ukuchaneka kokulawula kunye neemfuno zokugcina

Iimfuno zenkqubo yakho

Ukuhambelana nezixhobo ezifanayo kwindawo yakho

Masithi, umzekelo, inkqubo yakho ifuna ±5 grams, izixhobo zovavanyo ziyakwazi ±0.25 grams, kwaye umenzi uthi ukuchaneka kwesikali sakho yi ±0.25 grams. Ukunyamezela kwakho okuxeliweyo kuya kufuneka kube phakathi kwemfuno yenkqubo eyi-±5 grams kunye nokunyamezela komenzi ±0.25 grams. Ukuyicutha ngakumbi, ukunyamezela kolungelelwaniso kufuneka kuhambelane nezinye, izixhobo ezifanayo kwindawo yakho. Kufuneka usebenzise umlinganiselo wokuchaneka we-4:1 ukunciphisa ithuba lokubeka esichengeni imilinganiselo. Ngoko, kulo mzekelo, ukuchaneka kwesikali kufuneka kube yi-± 1.25 grams okanye i-finer (i-5 grams yahlulwe ngo-4 ukusuka kwi-4: 1 ratio). Ngaphezu koko, ukulinganisa ngokufanelekileyo isikali kulo mzekelo, igcisa lokulinganisa kufuneka lisebenzise umgangatho wobunzima kunye nokunyamezela ngokuchanekileyo ubuncinane be-± 0.3125 grams okanye i-finer (1.25 grams yahlulwe ngesi-4 ukusuka kumlinganiselo we-4: 1).
