Astaanta Diode Multimeter (Buugga)

Tijaabada diode waa habka ugu waxtarka badan uguna casrisan ee lagu hubinayo in dareerahaagu ay xaaladdoodu wanaagsan tahay ama ay xun tahay. Diode waa qalab koronto oo u ogolaanaya hadda inuu u socdo jiho gaar ah. Waxay leedahay cathode (negative) iyo anode (positive) dhamaado.

Dhanka kale, multimeter-ku waa aalad wax lagu cabbiro oo loo isticmaali karo in lagu cabbiro caabbinta, danabka, iyo hadda. Calaamadaha multimeter-ka ku yaal waxay ka caawiyaan inay qabtaan hawlahooda kala duwan. Waxa kale oo ay la timaadaa hogaanka tijaabada. Halkan ka daawo liiska oo dhan

Marka la soo koobo, si aad u tijaabiso diode, waa inaad qaaddaa tillaabooyinka soo socda. Marka hore, garaac garaaca mitirka mitirkaaga u rog calaamadda tijaabada diode oo dami awoodda wareeggaaga. Marka xigta, ku xidh talooyinka baadhista ee mitirka mitirka ee diode-ka. Hoggaaminta xun ee dhamaadka diode-ka (cathode) ee xun, iyo hogaaminta togan ee dhamaadka togan (anode) ee diode, ayaa hore u xaglinaysa. Kadib waxaad heli doontaa akhriska multimeterka. Qiimaha caadiga ah ee diode silikoon wanaagsan waa 0.5 ilaa 0.8V iyo diode germanium wanaagsan waa 0.2 ilaa 0.3V. Isku beddel hogaanka oo taabo diode jihada ka soo horjeeda, multimeterku waa inuu muujiyaa wax akhrin ah oo aan ahayn OL.

Maqaalkeena, waxaan ka wada hadli doonaa si faahfaahsan sida loo tijaabiyo diode leh multimeter.

Calaamada diode-ka-badan

Astaanta diode ee wareegyada waxaa badanaa lagu sawiraa sidii saddex xagal oo leh xariiq ka gudbaya xagga sare ee saddexagalka. Tani way ka duwan tahay multimeter-ka, multimeter-yada intooda badani waxay leeyihiin qaabka tijaabada diode, si aad u sameyso baaritaanka diode, waxaad u baahan tahay inaad garaacdo multimeterka u jeediso calaamadda diode ee multimeterka. Astaanta diode ee ku taal multimeter-ka waxay u eegtahay falaar tilmaamaysa bar toosan oo xariiqdu si joogto ah uga baxdo.

Waxaa jira dhowr calaamadood oo multimeter ah oo ku yaal hal-mitir kasta oo loo xilsaaray hawlo, sida Hertz, Voltage AC, DC current, capacitance, caabbinta, iyo tijaabada diode, iyo kuwo kale. Calaamadda diode-ka badan ee mitirka ah, falaartu waxay tilmaamaysaa dhinaca togan, baarka toosana wuxuu tilmaamayaa dhinaca taban.

Tijaabooyin diode

Tijaabada diode waxaa sida ugu fiican loo sameeyaa iyadoo la cabbirayo hoos u dhaca danab ee diode-ka marka korantada ku jirta diode ay ogolaato socodka dabiiciga ah ee hadda jira, i.. eexda hore. Laba hab ayaa loo isticmaalaa in lagu tijaabiyo diodh-yada leh multimeter-ka dhijitaalka ah:

1. Habka tijaabada diode: Tani waa habka ugu fiican uguna badan ee loo isticmaalo tijaabinta diodka. Shaqadani waxay horeba uga dhex jirtaa calaamadaha mitirka badan.
2. Habka iska caabinta: Tani waa hab kale oo la isticmaalo haddii multimeter-ku aanu lahayn qaabka tijaabada diode.

Hababka Tijaabada Diode

• U rog garaaca mitirka badan sumadda tijaabada diode ee ku taal multimeterka oo dami korontada wareeggaaga.
• Ku xidh talooyinka baadhista ee mitirka-mitirka ee diode-ka. Hoggaaminta xun ee dhamaadka diode-ka (cathode) ee xun, iyo hogaaminta togan ee dhamaadka togan (anode) ee diode, ayaa hore u xaglinaysa.
• Waxaad markaa heli doontaa akhriska multimeterka. Qiimaha caadiga ah ee diode silikoon wanaagsan waa 0.5 ilaa 0.8 V, iyo diode germanium wanaagsan waa 0.2 ilaa 0.3 V (1, 2).
• Isku beddel hogaanka oo taabo diode jihada ka soo horjeeda, multimeterku waa in aanu muujin wax akhris ah oo aan ahayn OL.

Si loo soo koobo

Marka imtixaanku u akhriyo eexda hore, waxay tusinaysaa in diode-ku uu ogolanayo in hadda uu u socdo jihada cayiman. Inta lagu guda jiro eexda, marka multimeter-ku muujiyo OL, taas oo macnaheedu yahay culeyska xad dhaafka ah. Multimeter-ka wanaagsani waxa uu tusa OL marka diode wanaagsan uu ka noqdo eexda.
