CalibrationKev kam rau siab yog txhais los ntawm International Society of Automation (ISA) raws li "kev tso cai sib txawv ntawm tus nqi teev; Tej zaum yuav raug qhia nyob rau hauv ntsuas ntsuas, feem pua ntawm ncua, los yog feem pua ntawm kev nyeem ntawv. "Thaum nws los txog rau calibration calibration, kam rau ua yog tus nqi ntawm qhov hnyav nyeem ntawv ntawm koj scale yuav txawv los ntawm lub nominal tus nqi ntawm cov huab hwm coj qauv uas muaj kev pom tseeb. Ntawm chav kawm, qhov zoo tshaj plaws, txhua yam yuav phim zoo kawg nkaus. Vim tias qhov ntawd tsis yog li ntawd, cov lus qhia ua siab ntev xyuas kom meej tias koj qhov ntsuas ntsuas ntsuas qhov hnyav hauv qhov ntau yam uas yuav tsis cuam tshuam rau koj lub lag luam.
Thaum ISA tshwj xeeb hais tias kev kam rau siab tuaj yeem nyob rau hauv ntsuas ntsuas, feem pua ntawm kev ncua lossis feem pua ntawm kev nyeem ntawv, nws yog qhov zoo tshaj plaws los suav cov ntsuas ntsuas. Kev tshem tawm qhov xav tau rau ib feem pua ntawm kev suav yog qhov zoo tagnrho, vim tias cov kev suav ntxiv no tsuas yog tawm ntau chav rau qhov yuam kev.
Cov chaw tsim khoom yuav qhia qhov tseeb thiab kev kam rau siab rau koj qhov ntsuas tshwj xeeb, tab sis koj yuav tsum tsis txhob siv qhov no raws li koj qhov chaw los txiav txim siab qhov kev ua siab ntev koj yuav siv. Es tsis txhob, ntxiv rau cov chaw tsim tshuaj paus kev zam, koj yuav tsum xav txog:
Kev tswj xyuas qhov tseeb thiab kev saib xyuas
Koj txoj kev xav tau
Kev sib raug zoo nrog cov cuab yeej zoo sib xws ntawm koj qhov chaw
Cia peb hais, piv txwv li, koj cov txheej txheem yuav tsum tau ± 5 grams, cov cuab yeej xeem muaj peev xwm ntawm ± 0.25 grams, thiab cov chaw tsim khoom hais tias qhov tseeb rau koj qhov ntsuas yog ± 0.25 grams. Koj qhov kev ntsuas ntsuas qhov ntsuas yuav tsum tau nyob nruab nrab ntawm cov txheej txheem yuav tsum tau ua ntawm ± 5 grams thiab cov chaw tsim khoom ua siab ntev ntawm ± 0.25 grams. Txhawm rau kom nws qis qis dua, qhov ntsuas qhov siab ntev yuav tsum ua raws li lwm cov twj paj nruag zoo sib xws ntawm koj qhov chaw. Koj yuav tsum tau siv qhov tseeb piv ntawm 4: 1 kom txo tau txoj hauv kev cuam tshuam cov calibrations. Yog li, hauv qhov piv txwv no, qhov tseeb ntawm qhov ntsuas yuav tsum yog ± 1.25 grams lossis finer (5 grams faib los ntawm 4 los ntawm 4: 1 piv). Tsis tas li ntawd, txhawm rau ntsuas qhov ntsuas tau zoo hauv qhov piv txwv no, tus kws tshaj lij calibration yuav tsum tau siv cov qauv loj nrog qhov raug siab ntawm qhov tsawg kawg nkaus ± 0.3125 grams lossis finer (1.25 grams faib los ntawm 4 los ntawm 4: 1 piv).
