Deteksi impedansi dan nilai minimum fungsi
Perangkat harus mendeteksi tangga resistor berikut pada aksesori. Aksesori
akan diuji dengan diagram sirkuit standar dalam diagram
yang diilustrasikan sebelumnya (Referensi Sirkuit Pengujian Headset) dengan impedansi total
diukur dari terminal MIC ke GND saat tombol ditekan dengan bias mic
2,2 V yang diterapkan melalui resistor 2,2 kOhm. Ini adalah resistansi efektif yang sama
seperti sirkuit deteksi tombol dengan mikrofon yang sejajar dengan resistor
tombol.
