Hababka Diode multimeter (buugga iyo tilmaamaha isticmaalka)

19.02.2023 /

Diode waa qalab elektaroonik ah oo u oggolaanaya hadda inuu u dhex maro hal jiho oo keliya, ma aha mid ka soo horjeeda. Diodes Semiconductor sida caadiga ah waxay leeyihiin mabda'a naqshad guud, kaas oo ah nooca P-nooca semiconductor block ku xiran N-nooca semiconductor block oo ku xiran laba terminal, kuwaas oo ah anode iyo cathode.

Wareegga toosiye waa wareeg elektaroonig ah oo ka kooban qaybo elektaroonig ah oo u beddela hadda beddelka u socda toosan. Wareegyada hagaajinta waxaa lagu isticmaalaa sahayda korantada DC ama qalabka RF ee qalabka raadiyaha. Wareegga toosiyaha ayaa inta badan ka kooban diodh-kooban si loo xakameeyo nalalka hadda jira iyo meerkuriga ama qaybaha kale.

Guud ahaan, habka ugu fiican ee loo tijaabiyo diode waa in la isticmaalo habka "Diode Test" ee multimeter kaaga, sababtoo ah habkani wuxuu si toos ah ula xiriiraa sifooyinka diode. Habkan, diode-ku waa mid hore u xaglinaya. Diode sida caadiga ah u shaqeeya ayaa qaadi doona hadda marka hore loo xagliyo waana inuu leeyahay hoos u dhac danab ah. Haddii qiimaha korantada ee la soo bandhigay uu u dhexeeyo 0.6 iyo 0.7 (loogu talagalay diode silikoon), markaa diodeku waa mid wanaagsan oo caafimaad qaba.

Tallaabooyinka cabbiraadda diode ee qaabka "Test Diode".

  • Go'aanso tiirarka togan iyo kuwa taban ee diodka.
  • Ku hay multimeter-kaaga dhijitaalka ah (DMM) qaabka tijaabada diode. Habkan, multimeter-ku waxa uu awood u leeyahay in uu keeno ku dhawaad ​​2 mA inta u dhaxaysa imtixaanada.(2)
  • Ku xidh hogaanka tijaabada madaw oo ku xidho terminaalka taban iyo baadhista cas ee u horseeda terminalka togan.
  • U fiirso wax-akhrinta ee soo bandhiga mitirka badan. Haddii qiimaha korantada ee la soo bandhigay uu u dhexeeyo 0.6 iyo 0.7 (loogu talagalay diode silikoon), markaa diodeku waa mid wanaagsan oo caafimaad qaba. Diodes germanium, qiimahani wuxuu u dhexeeyaa 0.25 ilaa 0.3.
  • Hadda ku beddel terminalka mitirka oo ku xidh baaritaanka madow ee terminalka togan iyo baaritaanka cas ilaa terminalka taban. Tani waa xaaladda eexda ee beddelka diode marka wax hadda socda uusan dhex socon. Sidaa darteed, mitirku waa inuu akhriyaa OL ama 1 (oo u dhiganta wareegga furan) haddii diodeku wanaagsan yahay.

Haddii mitirku muujiyo qiimayaal aan la xidhiidhin labada xaaladood ee kor ku xusan, markaa diode (1) waa khalad. Cilladaha diode waxay noqon karaan kuwo furan ama gaaban.

Maqaalkan, waxaan ku haynaa tilmaamo faahfaahsan oo ku saabsan habka "Diode Test" ee cabbiraadda diodes. Waxaan rajeyneynaa in aqoonta aan bixino ay kaa caawin doonto inaad wax badan ka barato qalabka korontada.
