Kaum Tswv yim rau kev siv cov digital motalimeter
1. Ua ntej siv, nws yog qhov tsim nyog los tshuaj xyuas seb txoj haujlwm hloov dua siab tshiab yog nyob rau hauv txoj kev ntsuas lub hwj chim thiab seb cov kev soj ntsuam yog nyob rau hauv lub ntswj ntsau.
2. Raws li cov kev xav tau ntawm "Grounding" lossis "xub" ntawm lub taub hau me me ntawm cov nplai, tus neeg kho tshuab xoom txoj haujlwm yuav tsum tau hloov kho ua ntej.
3. Xaiv cov khoom tsim nyog raws li qhov loj ntawm cov hluav taws xob ntsuas. Thaum ntsuas ntsuas voltage thiab tam sim no, sim deflicect tus pointer rau ntau dua 1/2 ntawm tag nrho cov nplai los txo qhov yuam kev. Yog tias koj tsis paub qhov loj me, koj tuaj yeem ntsuas thawj zaug nrog ntau qhov ntau thiab maj mam txo cov kab ke kom txog thaum tus neeg sib txawv. Tab sis thaum kuaj cov hluav taws xob siab (saum 100 volts) lossis siab tam sim no (ib yam li nws yuav ua rau nws tuaj yeem ua rau tus neeg sib tw hloov mus rau cov tswm ciab hloov mus rau cov tswm ciab.
4. Thaum ntsuas DC voltage lossis DC tam sim no, xyuam xim rau cov polarity ntawm cov khoom ntsuas ntsuas. Yog tias koj tsis paub txog cov ntsiab lus voltage ntawm ob lub ntsiab lus raug ntsuas, koj tuaj yeem hais qhia ob qho kev sim ntawm ob qho kev sim ntawm tus pointer cuam tshuam, thiab tom qab ntawd ntsuas dua.
5. Thaum ntsuas AC Volfage, nws yog qhov tsim nyog los txiav txim siab seb puas muaj qhov ntau ntawm AC Voltage yog nyob rau hauv cov kev ua haujlwm ntau ntawm cov multimeter. Feem ntau, cov kev ua haujlwm zaus ntau yam ntawm kev sib ntxiv yog 45-1500Z. Yog tias nws tshaj 1500Hz
Tus ntsuas kev ntsuas tus nqi yuav ua rau txo qis. Lub AC Voltage nplai yog raws tus nqi zoo ntawm sine yoj voltaged ntawm lub ac capitalitection zoo li no, thiab lwm yam.
6. Thaum ntsuas qhov ntsuas hluav taws xob ntawm qee qhov chaw hluav taws xob, nws yog ib qho tsim nyog los txiav txim siab seb qhov kev tsis kam yog ntau dua li lub nra ua tau. Yog tias tsis yog, vim yog cov nyhuv nyoos ntawm cov motimeter, tus nqi nyeem ntawv yuav qis dua tus nqi tiag tiag. Hauv qhov no, cov multiatal tsis tuaj yeem siv ncaj qha rau kev sim, thiab lwm txoj hauv kev yuav tsum siv hloov. Sab hauv kev tawm tsam ntawm ntau txoj kev siv tshuaj mulisance yog sib npaug ntawm cov hluav taws xob confitivity khij los ntawm tag nrho voltage muaj nuj nqis, xws li mf
-} qhov rhiab ntawm ib qho 300000 meter 'voltage ntau yog 5 kiloohms ntau yam yog 500 kiloothms. Feem ntau hais lus, sab hauv kev tawm tsam me me nyob rau hauv qhov ntau ntau ntau thiab loj nyob rau hauv ntau ntau ntau ntau ntau ntau ntau. Thaum kuaj qee qhov voltage nyob rau hauv cov ntau yam, yog tias sab hauv kev tawm tsam yog me me thiab cov kev tawm tsam shunt yog qhov loj, nws raug nquahu kom hloov mus rau qhov kev xeem qib siab. Txoj kev no, txawm hais tias lub pointer defection kaum ntse ntse yog me me, qhov tseeb yuav siab dua vim yog cov nyhuv me me. Muaj qhov xwm txheej zoo sib xws thaum ntsuas qhov tam sim no. Thaum pulatalisatal yog siv los ua ammeter, sab hauv kev tawm tsam ntawm ntau cov ntau yog me dua li ntawm ib qho me me.
7. Thaum ntsuas kev tiv thaiv, txhua lub hom phiaj ua haujlwm yuav tsum muaj
Xoom kev hloov kho. Tus nqi nyob rau ntawm lub chaw nyob ntawm geometric ntawm cov nplai tsis kam ntawm cov hluav taws xob tsis yeem ntawm cov iav, uas yog sib npaug ntawm cov khoom sib xyaw ntawm cov iav sib xyaw. Qhov chaw ib qho chaw sib npaug muaj txiaj ntsig yog 8. 10. 12. 13. 16. 20. 24. 25-30.}} Muaj ntau hom xws li 60}}} 75. The resistance scale is non-linear, so when using it, choose the appropriate gear so that the pointer points as close to the center as possible, usually at 0. The reading is accurate within the range of 1Ro-10Ro (Ro - median resistance), and there is a significant error outside of this range. Piv txwv li, qhov nruab nrab teev tus nqi ntawm MF10 mulcimeter yog 13, thiab hauv RX10 kiloohm ntau dua ro
{{0= ntawm 130 kWh, cov iav no haum rau kev sim ntawm 13 KWH -1. Ib 3 megaohm resistor.
8. Thaum ntsuas kev tiv thaiv nrog lub qhov kev sojntsuam liab tau txuas nrog lub davhlau me me hauv lub roj teeb, thiab cov kev sojntsuam dub txuas nrog lub zog zoo hauv lub ntsuas dej. Lub hom phiaj ntawm kev ua qhov no yog kom ntseeg tau tias qhov kev sib txuam ntawm cov kev sojntsuam liab hauv thiab cov kev sojntsuam dub tawm, thiab cov kev sojntsuam cov kev coj ua tsis tau thim rov qab. Nco ntsoov txuas cov kev sojntsuam liab mus rau qhov tsis zoo ntawm lub roj teeb thiab cov kev sojntsuam dub rau cov tranterized, donges, thiab electrolytic capacitors.
9. Thaum kuaj xyuas lub peev loj capacitors muaj peev xwm tiv thaiv cov iav, cov tshuaj ntsuam yuav tsum tau muab tso tawm ua ntej los tiv thaiv cov khoom seem los ntawm kev ua kom muaj kev puas tsuaj rau kev ua kom lub multimat. Ib qho kawg ntawm lub resistector ntawm kev sim Circuit Court yuav tsum tau txiav kom tsis txhob disconnected kom tsis txhob muaj tus cawv ntawm lwm cov neeg tawm tsam ntawm Circuital. Nws txwv tsis pub ntsuas qhov tsis kam ntawm kev ua haujlwm Circuit Court siv lub resistor.
10. Tom qab ntsuas ntsuas tau ua tiav, qhov hloov hloov yuav tsum tau tig mus rau lub iav siab siab kom tiv thaiv kev huam yuat hlawv ntawm lub caij thaum siv tau tom ntej. Yog tias muaj "dot" dub "lossis" tawm "yuav tsum tig mus rau txoj haujlwm no rau luv- Circuit Court lub ntsuas ntsuas.
