1. Tig lub multimeter mus rau 200 ohm thaiv, thiab ntsuas peb-theem resistances feem. Yog hais tias peb-theem resistances zoo ib yam thiab qhov sib txawv tsis loj, nws tuaj yeem txiav txim siab ua ntej tias peb-theem windings yog qhov qub thiab tsis muaj qhov sib cuam tshuam luv luv.
2. Ntsuas seb nws puas yog av, vim tias lub cev muaj zog raug hlawv, thiab qee zaum nws kuj yog av. Yog tias ib qho kawg ntawm × 1K lossis × 10k ob qhov kev sim ua rau kov lub xov hlau kawg thiab lwm qhov kawg kov lub casing, tus taw tes tsis zoo, thiab yog tias nws txav mus thiab qhov amplitude loj, nws tsis zoo.
3. Yog hais tias lub cev muaj zog yog ib-theem lub cev muaj zog, koj tuaj yeem ntsuas qhov kev tiv thaiv ntawm lub ntsiab windings U1 thiab U2 thiab lub thib ob windings Z1 thiab Z2. Feem ntau, qhov tsis kam ntawm qhov sib tw winding yog ntau dua li ntawm lub ntsiab winding. Yog hais tias qhov kev tiv thaiv ntawm lub thib ob winding yog me dua li ntawm lub ntsiab winding, tus nqi kuj qhia tau hais tias lub cev muaj zog yog burnt tawm.
