1, qhov tseeb qib ntawm lub ntsuas siab yog los cuam tshuam qhov tseeb ntawm qhov ntsuas tus nqi ze rau tus nqi tiag tiag hauv kev sib piv nrog cov lus precision. Nws yog qhov feem pua ntawm qhov sib piv ntawm qhov tseeb tus nqi ntawm qhov siab tshaj plaws qhov yuam kev mus rau qhov txwv siab tshaj ntawm qhov ntsuas, uas yog txiav txim los ntawm qhov loj ntawm qhov yuam kev generated hauv calibration.
3, Tuam Tshoj 2005 tshiab cov kev ntsuas ntsuas ntsuas ntsuas ntsuas tau tshaj tawm thiab siv, raws li JJG875-2005 cov cai ntsuas ntsuas ntsuas digital. Teem siab qhov tseeb ntxiv rau / {{0}}}01 feem pua, raws li, ntxiv lossis rho tawm 0.02 feem pua , ntxiv lossis rho tawm {{1{{13} }}}}.05 feem pua , ntxiv lossis rho tawm 0.1 feem pua , ntxiv lossis rho tawm 0.2 feem pua , ntxiv lossis rho tawm 0.5 feem pua , ntxiv lossis rho tawm 1.0 feem pua , ntxiv lossis rho tawm 1.6 feem pua .
4. Cov txheej txheem ntawm kev xaiv tsim nyog ntawm qhov raug qib ntawm qhov ntsuas siab yuav tsum yog raws li qhov yuav tsum tau ua ntawm cov cuab yeej tsim khoom, kev lag luam thiab kev ua haujlwm, kev tshawb nrhiav, thiab lwm yam, thiab qhov kev tso cai yuam kev yuav tsum tau siv los ntawm tus nqi tsawg kawg nkaus ntawm kev ntsuas siab yuav tsum tau siv los xaiv. qib raug.
