Yuav ua li cas calibrate lub multimeter
1. Ua ntej saib lub dial ntawm lub multimeter, koj yuav pom tias lub multimeter yuav muaj ntau lub zog, tab sis cov iav no yog tag nrho cov yuav tsum tau calibrated.
2. Tom qab ntawd siv tus qauv los ntsuas lub ntsuas ntsuas. Thaum calibrating lub hwj huam mov, tso zis voltages ntxiv rau 100mV, ntxiv rau 1V, ntxiv rau 10V, ntxiv rau 100V thiab ntxiv rau 1000V raws, thiab sau cov nqe lus qhia raws.
3. Thaum calibrating DC voltage thaiv ntawm lub multimeter, tso zis voltages ntawm 200mV, 2V, 20V, 200V thiab 1000V raws, thiab sau tus nqi qhia.
4. Thaum ntsuas cov khoom siv hluav taws xob, koj yuav tsum tau siv lub thawv ntim khoom rau kev ntsuas. Tus nqi tsis kam ntawm lub thawv tsis kam siv feem ntau yog 200Ω-20MΩ, thiab tom qab ntawd ntsuas ntau qhov kev tiv thaiv thiab sau lawv cais.
5. Tus nqi sau tseg tau muab piv los saib seb tus nqi yuam kev yog nyob rau hauv qhov kev taw qhia qhia. Yog tsis yog, nws yog unqualified.
Cov saum toj no yog cov txheej txheem multimeter calibration. Cov phooj ywg xav tau tuaj yeem hu rau Shenzhen Jingyu Aerospace Testing. Shenzhen Jingyu Aerospace Testing yog ib lub koom haum muab ntawv pov thawj dual-certified.
