1. Sarudza chishaki chakakodzera: Kana voltage yekushanda yemota iri kuyedzwa iri 380V, saka tinogona kusarudza chishaki che500V.
2. Zunza wachi kuti isashande zvakanaka, ita bvunzo ye "short-circuit test", bvisa "decline" mapeni maviri e "test", uye zunza "handle pointer" pedyo ne0 zvakanaka.
3. Patsanura mapeni maviri ekuyedza, zunza mubato, uye pointer inenge iri pedyo nekusingaperi.
4. Pakuyera, zvakanakisisa kubvisa chidimbu chinobatanidza chemota yechikamu chetatu, ganda racho rakadzika, uye materminal epasi emawinding matatu anofanira kuunganidzwa, U, V, W kubva kuruboshwe kuenda kurudyi.
5. Danho rekutanga: kuyera kusimba kwekudzivirira kupisa pakati pemagumo emagetsi matatu nekasi, E inobata kasi yemota, L inobata materminal matatu U, V, uye W zvakateerana, zunza mubato nekukurumidza (120 revolutions paminiti), uye mirira kuti pointer igadzikane pa infinity Insulation yakanaka kana iri pedyo.
6. Danho rechipiri: Yera kuputira pakati pezvikamu zvitatu zveU, V, uye W. Yera kuputira kamwe chete kaviri. Kana seti nhatu dzezvinoratidza data dzese dzisingaperi, kuputira kwakanaka.
7. Inogonawo kuyerwa pasina kubvisa chidimbu chinobatanidza. Uyu ndiwo musiyano uripo pakati pe nyeredzi ne delta wiring. Mukugadzirwa kwenyeredzi, kuramba kuri pakati pemapoinzi matatu U, V, W ne neutral point kunogona kuyerwa. Mapoinzi matatu e resistance values akafanana. Zvakanaka, U, V, W mapoinzi matatu anoyerwa muzvikamu zviviri, uye kukosha kwekuramba kwakafanana zvakanaka. Zvakarurama kuyera kukosha kwekuramba ne multimeter, uye kuyera kuramba pasi panguva imwe chete.
