LED dej ntws yaug: lub lag luam thiab cov lus qhia rau kev siv. Txheej txheem cej luam ntawm pab kiag li lawm rau qhov nrhiav kom tau ntawm zais thaiv

Qhia Tau Rau (muab zais xov tester) yog npaj feem mus nrhiav voltage circuits. Yog li ntawd nws yog paub qhov sib txawv electromagnetic tawg. Fais fab perceptible qhia teeb liab nyob rau hauv tus qauv. Feem ntau, tus ntaus ntawv yog tau los xyuas electromagnetic tawg hwj chim rau 0.4 mW.

Lwm feature ntawm testers yog mus nrhiav hlau tej khoom. Nyob rau hauv cov ntaub ntawv no, nws tseem tau mus ntes lawv tsuas yog nyob rau ib tug deb ntawm tus dais. Feem ntau, qhov no tshaj plaws deb tej zaum yuav 55 hli. Nyob rau hauv no hais txog, cov haib tshaj yog cov ib txwm hlau detectors. Xyuas lub sam xeeb ntawm lub network yuav tsum tau tiv thaiv tus kuj nyob 50 ohms. Ib co ua qauv yog muaj los mus txiav txim lub polarity ntawm cov nyob ntawm tej. Nws yuav tsuas yuav nqa tawm ntawm qhov tam sim no.

vaj huam sib luag ntes

Nyob rau hauv pem hauv ntej ntawm lub ntsuas no yog qhov ib tug mus hom, raws li zoo raws li lub regulator. Nws yog npaj mus nrhiav hlau tej khoom. Nyob rau hauv tas li ntawd, lub sab ntawm tus dais no yog ib tug khawm kom qhib lub teeb xais uas yuav pab tau ua hauj lwm nyob rau hauv ib chav tsev tsaus. Nyob rau sab tod los ntawm qhov taw qhia muaj ib tug movable hu sojntsuam thiab sensor uas yog tau koom ua ke. Tom qab ntawm cov ntaus ntawv nyob ze qhov khoom yog ntaus cim hu phaj.

Xyuas cov ntaus ntawv thiab calibrate

Xyuas qhov taw qhia ntawm efficiency yog heev yooj yim. Ua ntej ntawm tag nrho cov nws yog tsim nyog los configure tus ntaus ntawv mus. Raws li ib tug txoj cai, nws muaj peev xwm mus nyob peb txoj haujlwm. Nyob rau hauv cov ntaub ntawv no, nws yuav tsum tau muab tso rau hauv nruab nrab. Cov kauj ruam thib ob yog los kho cov kev sojntsuam. Ua li no, siv cov kev sib cuag phaj, uas yog nyob rau ntawm lub hauv qab ntawm qhov ntsuas. Tom ntej no, cov kev sojntsuam yog muab tso rau ntawm lub kaum sab xis ntawm raws nraim 90 degrees. Tsuas yog ces yuav thawb cov kev sib cuag electrode nyob rau sab ntawm lub ntsuas vaj huam sib luag. Yog hais tias xov tester yog ua hauj lwm kom zoo, thiab lub voltage ntawm lub roj teeb yog nkag, nws ua hauj lwm instantly tso tawm kom pom. Tsis tas li ntawd, nyob rau hauv ntau cov qauv nrog rau cov quas ntus suab teeb liab.

Calibrate qhov taw qhia hloov yog teem rau lub thawj txoj hauj lwm. Tom qab ntawd, lub phaj yog raug tshem tawm, thiab cov kev sojntsuam yog teem rau ntawm lub kaum sab xis ntawm 180 degrees. Tom ntej no, koj yuav tau teem lub rhiab heev ntawm lub regulator. Rau lub hom phiaj no, koj yuav tsum tig lub dial mus txog rau lub heev kawg. Tom qab ntawd tus ntaus ntawv ua hauj lwm nyob rau hauv cov zaub system. Rau calibration yuav tsum pib tig lub log nyob rau hauv kev coj rov qab, thiab tos kom txog thaum lub teeb mus. Thaum zoo li no teeb liab yuav tau nres.

Nyob rau hauv xaus, koj yuav tau tawm hauv lub rhiab heev regulator thiab noj tej hlau hlau. LED yaug nws yog tsim nyog los noj tsawg kawg yog 30 mm. Yog hais tias lub LED nyob rau tib lub sij hawm ua hauj lwm dua, tus ntaus ntawv calibration yog kev vam meej.

siv taw qhia

Yuav ua li cas mus saib hauv lub xov nyob rau hauv lub apartment? Yuav kom nrhiav tau ib tug alternating tam sim no Circuit Court nrog ib tug thawj hom siv rau tus ntaus ntawv. Nws yuav muab tso rau los ntawm txoj kev ib tug mus nyob rau sab ntawm lub ntaus ntawv. Cov tsev txav sensor yuav tsum tau tuaj txoos ua ke. Yuav kom txiav txim seb qhov chaw qhia kiag ntawm lub saw yuav tsum nrog cov phab ntsa qhov hluav taws xob. Thaum lub sij hawm kev lag luam, nws yog ib qho tseem ceeb kom lub tester rau ntawm phab ntsa taub hau-on.

Yog hais tias koj deploy lub ntaus ntawv, nws yog tsim nyog los hloov qhov rhiab heev qhov chaw. Qhov no yuav ua tau siv ib tug tshwj xeeb regulator. Yog yuav tshawb kom rau electromagnetic tawg siv nyob rau hauv lub thib ob hom Circuit Court. Thaum lub rooj noj kev sojntsuam yuav tsum tau nyob twj ywm nyob rau hauv lub tuaj txoos ua ke xeev qab lub phaj. Tus thawj lub teeb liab yog soj ntsuam nyob rau hauv lub nplos. Ntxiv lub ntaus ntawv yuav tsum zoom tawm ntawm nws thiab mus saib xyuas qhov taw qhia readings. Yog hais tias lub lub teeb liab thaum lub sij hawm lub lag luam tsis tshwm sim, nyob rau ntawm no point yog tsis muaj saw. Nyob rau hauv tas li ntawd, nws yog ib qho tseem ceeb coj mus rau hauv tus account uas tus ntaus ntawv yuav qhia cov teeb liab zog yog tsis ntau tshaj li 0.4 mW.
