Tswv yim General Troubleshooting Method for Digital Multimeters
1. Hais txog kev ua haujlwm sib txawv thaum tsis saib xyuas qhov sib txuam ntawm cov ntawv txuas
Qee cov neeg siv khoom muaj txiaj ntsig ntawm ntau hom kev ua haujlwm ntawm multimeter thaum ua kev yuav khoom, tab sis lawv nyiam saib qhov sib txuam ntawm cov khoom siv. Yog tias tsis muaj cov ntaub ntawv tsim nyog, kev ua haujlwm sib txawv tsis tuaj yeem ua tiav lawm. Piv txwv li, qee cov neeg siv cia siab tias lub tshuab multimeter lawv yuav tuaj yeem kuaj xyuas qhov pib tam sim no thiab qhov kub thiab txias nyob rau hauv ntau yam mob, tab sis lawv tsis yuav cov khoom tshwj xeeb tam sim no clamps thiab ntsuas kub ntsuas. Yog tias koj xav siv tag nrho cov haujlwm ntawm lub tsheb multimeter, qhov sib txuam ntawm qee cov khoom siv tseem ceeb heev. Qee qhov ntawm cov ntawv txuas no yog qhov tseem ceeb, thaum lwm tus sib tw ua haujlwm ntawm lub tsheb multimeter.
Cov khoom siv feem ntau muaj nyob rau hauv lub tsheb multimeter suav nrog inductive pickups, roj teeb alligator clips, SMD nto mount tivthaiv tshwj xeeb kev xeem clips (siv los kuaj SMD tsis kam, capacitance, inductance, thiab transistor tsis, tuaj yeem ua haujlwm nrog ib txhais tes, ua kom yooj yim dua), tam sim no sensors, siab probes, torque probes, thiab IC probes. Cov ntawv txuas no feem ntau tsis tshua siv hauv kev saib xyuas. Rau cov tuam txhab kev saib xyuas, thaum xaiv cov khoom siv, lawv yuav tsum xav txog ntau yam xws li cov neeg siv khoom zoo, lub tuam txhab kev saib xyuas nyiaj txiag, thiab kev siv txhua hnub, txhawm rau txiav txim siab tsim nyog thiab ua tiav cov khoom siv ntau tshaj plaws.
2. Kev tso tseg cov khoom siv zoo vim muaj kev cuam tshuam cov lus yooj yim
Qee cov neeg siv xav yuav cov tsheb multimeters txawv teb chaws, tab sis tom qab tshawb pom tias cov lus interface yog lus Askiv, lawv yooj yim muab ntau dua ua haujlwm lossis cov khoom lag luam. Qhov tseeb, tsis tas yuav ua li ntawd. Cov haujlwm tseem ceeb ntawm ntau yam multimeters tsis txawv ntau, thiab ntau lub zog tau txheeb xyuas los ntawm cov cim thoob ntiaj teb, ua rau lawv yooj yim siv. Nrog kev kawm yooj yim, ib tus tuaj yeem ceev cov txheej txheem siv.
