Pengujian Dioda Tegangan Tinggi (High Voltage Diode)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dioda HV microwave tidak bisa diukur seperti dioda biasa karena strukturnya terdiri dari banyak dioda internal yang disusun seri.

Pengujian Trafo Tegangan Tinggi (High Voltage Transformer \/ HVT)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Trafo HVT memiliki 3 bagian lilitan: Lilitan Primer (220V), Lilitan Sekunder (Tegangan Tinggi), dan Lilitan Filamen (Tegangan Rendah ke Magnetron).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Langkah Pengujian (Skala Ohm X1):<\/strong>\n<ol class=\"wp-block-list\">\n<li><strong>Lilitan Primer:<\/strong> Ukur dua pin terminal input bawah.

Jika 0 Ohm (korslet) atau tak terhingga (putus).<\/li>\n\n\n\n<li><strong>Lilitan Filamen:<\/strong> Ukur dua kabel soket output atas yang menuju ke Magnetron. Nilai normal berkisar mendekati <strong>0 Ohm<\/strong> (karena lilitannya tebal dan pendek).<\/li>\n\n\n\n<li><strong>Lilitan Sekunder (HV):<\/strong> Cari satu terminal pin tunggal output HV (biasanya memiliki skun besar terisolasi). Tempelkan <em>probe<\/em> satu ke terminal tersebut, dan <em>probe<\/em> lainnya ke <strong>inti besi\/bodi trafo<\/strong> (karena ujung lilitan sekunder HVT sengaja di-<em>ground<\/em>-kan ke bodi trafo).
