Mosiyana ndi ma voltage detectors, ma voltage testers amayenera kukhudzana ndi gwero lamagetsi kuti agwire ntchito. Oyesa magetsi ali ndi ma probe achitsulo omwe amalowetsedwa mumayendedwe amagetsi. Mpweya umayesedwa mofanana ndi dera, kotero tester si gawo lofunikira la dera. Mwayiwala tanthauzo la "parallel"? Onani: Phunziro la Magetsi la Wonka Donka.
Oyesa magetsi amawerengera ma voltage enieni ndikukupatsirani manambala oti mugwire nawo m'malo mongozindikira kukhalapo kwa magetsi.
chizindikiro
Oyesa magetsi amatha kupereka nambala yolondola ngati ali ndi chinsalu, koma nthawi zambiri zizindikirozo zimapangidwa mu mawonekedwe a sikelo ya LED. Sikelo iyi ipereka mitundu, osati nambala yeniyeni, yamagetsi.
Kotero, mwachitsanzo, pakhoza kukhala ma LED olembedwa 6, 12, 24, 60, 120, 230, ndi 400. Ndiye ngati mutayesa chinachake ndi magetsi a 30, ma LED 6,12, 24, ndi 24 adzawunikira; zomwe zikuwonetsa kuti muli ndi mphamvu pakati pa 60 ndi XNUMX. Onetsetsani kuti muyang'ane malangizo a chitsanzo chilichonse kuti muwone momwe chimagwirira ntchito.
Kodi ma voltage testers angagwiritsidwe ntchito chiyani?
Zoyesa magetsi zimatha kugwiritsidwa ntchito pamagetsi onse a DC ndi AC, kotero ndizotheka kuyesa mabatire ndi choyesa magetsi. Zofanana ndi chowunikira ma voltage, zidazi zitha kugwiritsidwanso ntchito kuyesa ma sockets ndi ma circuit breakers. Komabe, amathanso kuyang'ana kupitiliza ndi polarity chifukwa ali ndi kafukufuku wapawiri ndipo amalumikizana ndi dera.
