Kev khiav hauj lwm txoj kev thiab kho cov lus qhia rau Digital Multimeters
① Sensory Inspection Method Txiav txim qhov ua txhaum ncaj qha los ntawm tib neeg lub siab. Kev kuaj pom pom tuaj yeem kuaj xyuas cov xov hlau tawg, cov pob qij txha txias, txuas txuas luv luv, lub tshuab hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam. Tsis tas li ntawd, manually tshawb xyuas cov khoom xoob xoob, ruaj ntseg IC pins thiab daig teb hloov pauv. Mloog cov suab txawv txav thiab hnov tsw rau cov ntxhiab tsw txawv txawv.
② Voltage Measurement Method Ceev nrooj nrhiav cov ntsiab lus txhaum los ntawm kev ntsuas seb qhov kev khiav hauj lwm voltage ntawm txhua qhov ntsuas qhov tseem ceeb yog qhov qub, xws li kev khiav hauj lwm voltage thiab siv voltage ntawm A / D converter.
③ Short-Circuit Method Txoj kev luv-circuit feem ntau yog siv rau hauv cov txheej txheem tshuaj xyuas saum toj no rau A / D converters thiab dav siv thaum kho cov twj tsis muaj zog-tam sim no thiab microelectronic.
④ Qhib-Circuit Method Disconnect qhov xav tias seem ntawm cov khoom tiav lossis chav tsev Circuit Court. Yog hais tias qhov txhaum ploj mus, qhov tsis xws luag nyob rau hauv lub disconnected Circuit Court. Txoj kev no feem ntau yog siv rau circuits nrog luv-circuit faults.
⑤ Kev Ntsuas Cov Txheej Txheem Thaum qhov ua txhaum yog nqaim mus rau ib qho chaw lossis ob peb yam, ua qhov ntsuas hauv Circuit Court lossis off-circuit. Yog tias tsim nyog, hloov qhov xav tias qhov seem nrog ib qho kev paub zoo. Yog tias qhov txhaum ploj tom qab hloov pauv, cov khoom qub tsis raug.
⑥ Txoj kev cuam tshuam Siv tib neeg induced voltage raws li lub teeb liab cuam tshuam thiab saib cov kev hloov ntawm LCD zaub. Txoj kev no feem ntau yog siv los xyuas seb puas muaj cov khoom siv hluav taws xob thiab cov lus qhia ua haujlwm zoo.
