Lub desktop digital multimeter ntsuas voltage li cas?
Kev npaj
Ua ntej siv lub desktop digital multimeter los ntsuas qhov voltage, koj yuav tsum tau npaj cov hauv qab no:
1. Xyuas kom tseeb tias cov khoom siv hluav taws xob txuas nrog. Desktop digital multimeters yuav tsum tau txuas nrog lub zog hluav taws xob kom ua haujlwm zoo.
2. Txiav txim siab hom voltage yuav tsum ntsuas. Cov hom hluav taws xob sib txawv yuav tsum tau siv cov ntsuas hluav taws xob sib txawv. Piv txwv li, ntsuas AC voltage thiab DC voltage yuav tsum tau siv cov kev sojntsuam sib txawv.
3. Txuas lub sojntsuam mus rau lub multimeter. Ntxig cov xov hlau liab thiab dub ntawm qhov kev sojntsuam mus rau hauv cov liab thiab dub jacks ntawm lub multimeter feem, thiab xyuas kom meej tias qhov kev sib txuas ruaj khov.
Kev ntsuas cov kauj ruam
1. Qhib lub multimeter. Nias lub hwj huam hloov thiab tos kom lub multimeter nws tus kheej-test kom tiav, xyuas kom meej lub multimeter screen qhia xoom.
2. Xaiv hom kev ntsuas. Nyob ntawm seb hom voltage yuav tsum ntsuas, xaiv hom ntsuas tsim nyog. Rau AC voltage, koj yuav tsum xaiv AC voltage ntau; Rau DC voltage, koj yuav tsum xaiv qhov DC voltage ntau.
3. Txuas qhov kev sojntsuam mus rau lub voj voog hauv kev sim. Txuas cov xov hlau liab thiab dub ntawm qhov kev sojntsuam mus rau qhov zoo thiab qhov tsis zoo ntawm lub voj voog hauv kev sim.
4. Nyeem qhov ntsuas ntsuas. Ntawm lub vijtsam multimeter, koj tuaj yeem pom tus nqi tam sim no. Yog tias koj xav tau sau cov txiaj ntsig ntsuas, koj tuaj yeem thaij duab lossis kaw lawv manually.
5. Tua lub multimeter. Tom qab ua tiav qhov ntsuas, lub multimeter yuav tsum tau muab tua kom txuag tau lub zog thiab tiv thaiv lub ntsuas.
Cov kev ceev faj
1. Thaum siv lub desktop digital multimeter los ntsuas qhov voltage, koj yuav tsum tau xyuam xim rau cov teeb meem kev nyab xeeb. Tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab, koj yuav tsum xyuas kom meej tias koj khaws ib qho kev ncua deb ntawm lub voj voog nyob rau hauv kev sim kom tsis txhob muaj kev sib tsoo hluav taws xob.
2. Thaum xaiv hom ntsuas, koj yuav tsum tau ua tib zoo saib xyuas qhov txawv ntawm AC voltage thiab DC voltage. Ntau hom voltages yuav tsum tau siv cov kev sojntsuam sib txawv thiab kev ntsuas, txwv tsis pub cov ntsuas ntsuas yuav tsis raug.
3. Thaum lub sij hawm ntsuas kev ntsuas, koj yuav tsum tau them sai sai rau seb qhov screen zaub ntawm lub multimeter thiab qhov ntsuas tau ruaj khov. Yog tias pom muaj qhov txawv txav, nws yuav tsum tau kho nrog lub sijhawm thiab ntsuas dua.
4. Tom qab ua tiav qhov ntsuas, lub multimeter yuav tsum tau muab tua nyob rau hauv lub sij hawm los tiv thaiv lub ntsuas thiab ncua nws cov kev pab cuam lub neej. Nyob rau tib lub sijhawm, kev sojntsuam thiab cov cables kuj yuav tsum tau teeb tsa thiab khaws cia kom zoo kom tsis txhob muaj kev puas tsuaj lossis poob.
