Kev kho kom raugKev kam rau siab yog txhais los ntawm Lub Koom Haum Thoob Ntiaj Teb ntawm Kev Ua Haujlwm Tsis Siv Neeg (ISA) ua "kev hloov pauv uas tso cai los ntawm tus nqi teev tseg; tej zaum yuav qhia hauv cov chav ntsuas, feem pua ntawm qhov ntev, lossis feem pua ntawm kev nyeem." Thaum nws los txog rau kev ntsuas qhov ntsuas, kev kam rau siab yog qhov ntau npaum li cas qhov hnyav nyeem ntawm koj lub nplai tuaj yeem txawv ntawm tus nqi nominal ntawm tus qauv hnyav uas muaj qhov tseeb zoo tshaj plaws. Tau kawg, qhov zoo tshaj plaws, txhua yam yuav phim zoo meej. Vim tias qhov ntawd tsis yog qhov tseeb, cov lus qhia kev kam rau siab xyuas kom meej tias koj lub nplai ntsuas qhov hnyav hauv qhov ntau uas yuav tsis cuam tshuam tsis zoo rau koj txoj kev lag luam.
Txawm hais tias ISA hais meej tias kev kam rau siab tuaj yeem ua cov chav ntsuas, feem pua ntawm qhov ntev lossis feem pua ntawm kev nyeem ntawv, nws yog qhov zoo tagnrho los xam cov chav ntsuas. Tshem tawm qhov xav tau rau kev suav feem pua yog qhov zoo tagnrho, vim tias cov kev suav ntxiv tsuas yog tso chaw ntau dua rau qhov yuam kev.
Tus neeg tsim khoom yuav qhia meej qhov tseeb thiab kev kam rau siab rau koj qhov ntsuas tshwj xeeb, tab sis koj yuav tsum tsis txhob siv qhov no ua koj qhov chaw tsuas yog los txiav txim siab qhov kev kam rau siab calibration uas koj yuav siv. Es tsis txhob, ntxiv rau qhov kev kam rau siab uas tus neeg tsim khoom tau teev tseg, koj yuav tsum xav txog:
Kev cai lij choj kom raug thiab kev saib xyuas
Koj cov kev xav tau ntawm cov txheej txheem
Kev sib xws nrog cov cuab yeej zoo sib xws ntawm koj qhov chaw
Piv txwv li, koj cov txheej txheem xav tau ±5 grams, cov khoom siv kuaj muaj peev xwm ua tau ±0.25 grams, thiab lub chaw tsim khoom hais tias qhov tseeb rau koj qhov nplai yog ±0.25 grams. Koj qhov kev kam rau calibration uas tau teev tseg yuav tsum nyob nruab nrab ntawm qhov yuav tsum tau ua ntawm ±5 grams thiab lub chaw tsim khoom qhov kev kam rau ±0.25 grams. Yuav kom nws nqaim dua, qhov kev kam rau calibration yuav tsum sib xws nrog lwm cov cuab yeej zoo sib xws ntawm koj lub chaw. Koj kuj yuav tsum siv qhov sib piv ntawm qhov tseeb ntawm 4:1 kom txo qhov muaj feem cuam tshuam rau cov calibrations. Yog li, hauv qhov piv txwv no, qhov tseeb ntawm qhov nplai yuav tsum yog ±1.25 grams lossis zoo dua (5 grams faib los ntawm 4 ntawm qhov sib piv 4:1). Ntxiv mus, txhawm rau calibrate qhov nplai kom raug hauv qhov piv txwv no, tus kws kho calibration yuav tsum siv tus qauv loj nrog qhov kev kam rau qhov tseeb ntawm tsawg kawg ±0.3125 grams lossis zoo dua (1.25 grams faib los ntawm 4 ntawm qhov sib piv 4:1).
