B efore ua ntsuas tshuab calibration, peb lam xav tias lub tshuab yog nyob rau hauv kev ua raws cai, ces muab tso rau txheej txheem rotor rau qhov nqi koj tshuav tshuab rau calibration (uas yog ntxiv ib tug qauv xeem loj), tom qab lub calibration tiav, yog tias ncaj nruab nrab tshuab tso tawm kom pom tus nqi sib txawv yog Loj loj, koj tuaj yeem xav tias lub tshuab tshuav nyiaj poob haujlwm.
(A) Tsawg tshaj qhov ua tau tiav tsis tiav cov khoom tsis ua tiav.
Txuas ntxiv rau kev sib tw ntawm 0 & deg; 30 & deg; 60 & deg; 90 & deg; 120 & deg; 150 & deg; 180 & deg; 210 & deg; 240 & deg; 270 & deg; 300 & deg; 330 & deg; Nyeem thiab sau tus xov tooj rau lub rooj.
2. Sau tag nrho cov zauv thiab sib faib nws los ntawm 12 thiab xam cov qib zauv ntawm txhua lub dav hlau. Qhov nruab nrab khaws tseg hauv seem "nruab nrab" kem, xws li Table 1 qhia. Tom qab ntawd faib txhua qhov nyeem los ntawm qhov nruab nrab ntawm nws cov dav hlau sib txawv thiab sau cov qhab nia ntawm qhov "ntau ntau".
3. Lub txiaj ntsig tau tshwm sim yog teeb, raws li qhia hauv daim duab 2.
Cov kab hauv kab hauv cov duab sawv cev ntawm cov lus txhais ntawm txhua lub dav hlau nyeem. Ob txoj kab ntawm kab (0.88 thiab 1.12) yog qhov nruab nrab ntawm txhua lub dav hlau suav tau muaj kev txwv ntawm & ntxiv nrog rau; 12%.
(B) Qhov kev txo qis ntawm qhov tsis txaus siab
1. Muab kev ntsuam xyuas ntau ntawm 0 & hauv qhov kaum ob lub "N" qhov ntawm qhov kev xeem sab laug thiab 90 thiab ntu ntawm sab xis.
2. Ua qhov kev kuaj ntawd. Nyob rau hauv txhua qhov kev kuaj, sab laug ntiv taw mus rau 30 & deg; 60 & deg; 90 & deg; 120 & deg; 150 & deg; 180 & deg; 210 & deg; 240 & deg; 270 & deg;
300 & deg; 330 & ntaum; Tib lub sij hawm, txav mus rau qhov loj mus rau 60 & qes; 30 & deg; 0 & deg; 330 & deg; 300 & deg; 270 & deg; 240 & deg; 210 & deg; 180 & deg; 150 & deg; Txhua zaus koj sim sau cov ntaub ntawv ib zaug. Kos rau hauv daim ntawv qhia. Tag nrho cov nyeem yog tsim nyog nyob rau hauv lub cheeb tsam uas tsim nyog. Cov txiaj ntsim tau tshwm nyob hauv daim duab 3.
3. Tag nrho cov ntsiab lus ntawm qhov kev soj ntsuam tau raug poob hauv 90% ntawm lub vajvoog uas tau pom zoo, ces qhov txo qhov tsis txaus yuav nce siab tshaj 90%.
Yog tias nws tsis tshua muaj peev xwm tshuav tsawg kawg nkaus thiab qhov txo qhov tsis txaus ntseeg ob leeg dhau qhov kev kho mob tseem ceeb, lub tshuab ntsuas qis yog tsim nyog.
