Yuav Ntsuas Li Cas Bipolar Transistors Yog tias Koj Muaj Analog Multimeter

Peb paub yuav ua li cas transistor ua haujlwm tab sis qee tus ntawm peb tsis paub tiag yuav sim ntsuas cov khoom siv nws tus kheej li cas. Tam sim no, feem ntau Digital Multimeters muaj qhov nyob rau hauv los ntsuas lawv, tab sis koj yuav ua li cas yog tias koj muaj cov qub Analog/Needletype? Nov yog txoj hauv kev yooj yim los ua.

Kauj Ruam 1: Yooj Yim Kho

Bipolar transistors muaj 3 tus pin, Tus Emitter (E), Base (B) thiab Collector (C) uas feem ntau txuas nrog rau lub casing rau feem ntau lub zog transistors (TO-3 casing). Nws tuaj yeem muab cais ua ob qho, NPN thiab PNP teeb tsa, saib daim duab 2. Qhov kev ntsuas no yog ua raws txoj kev xav uas lub transistor zoo li ob lub diodes txuas ua ke, saib daim duab 1.

Kauj Ruam 2: Rau PNP Transistors

1. Teem koj lub Analog Multimeter rau Ohmmeter X1 Ohm Scale.2. Txuas qhov Kev Ntsuam Xyuas Tsis Zoo (Dub) rau Emitter thiab Tshawb Fawb Zoo (Liab) rau Lub Hauv Paus. Lub koob yuav tsum tig mus rau sab xis, nyeem tsawg dua 100 ohms.3. Tam sim no hloov qhov kev sib txuas sojntsuam mus rau Emitter rau Red Probe thiab rau Base rau Dub. Koob yuav tsum tsis txhob thim rov qab.

Yog tias cov txiaj ntsig zoo ib yam li saum toj no, koj qhov kev sib txuas Emitter-Base zoo

4. Tam sim no peb yuav sim qhov Base-Collector hlws ris. Txuas qhov kev sojntsuam Liab mus rau Lub Hauv Paus thiab Kev Tshawb Fawb Dub rau Tus Neeg Sau. Koob yuav tsum tig mus rau sab xis, kev tiv thaiv feem ntau tsis tsawg dua 100 ohms.5. Hloov qhov kev sojntsuam dua, Dub rau lub hauv paus thiab Liab sojntsuam mus rau Tus Sau. Koob yuav tsum tsis txhob txav mus.

Yog tias cov txiaj ntsig zoo ib yam li saum toj no, koj li Base-Collector hlws ris yog Ok

6. Txuas tus neeg sojntsuam mus rau Emitter thiab Collector (kev sojntsuam tuaj yeem hloov pauv), kev nyeem ntawv siab dua 1Kohms qhia tias ua haujlwm transistor.

Kauj Ruam 3: Rau NPN Transistors

1. Teem koj lub Analog Multimeter rau Ohmmeter X1 Ohm Scale.2. Txuas Cov Kev Ntsuam Xyuas Tsis Zoo (Dub) rau Lub Hauv Paus thiab Qhov Kev Tshawb Fawb Zoo (Liab) rau Tus Emitter. Lub koob yuav tsum tig mus rau sab xis, nyeem tsawg dua 100 ohms.3. Tam sim no hloov qhov kev sib txuas sojntsuam mus rau Lub Hauv Paus rau Kev Tshawb Fawb Liab thiab rau Emitter rau Dub. Koob yuav tsum tsis txhob thim rov qab.

Yog tias cov txiaj ntsig zoo ib yam li saum toj no, koj qhov kev sib txuas Emitter-Base zoo

4. Tam sim no peb yuav sim qhov Base-Collector hlws ris. Txuas qhov kev sojntsuam Dub rau Lub Hauv Paus thiab Kev Tshawb Fawb Liab rau Tus Sau. Koob yuav tsum tig mus rau sab xis, kev tiv thaiv feem ntau tsis tsawg dua 100 ohms.5. Hloov qhov kev sojntsuam dua, Liab rau Lub Hauv Paus thiab Dub sojntsuam mus rau Tus Sau. Koob yuav tsum tsis txhob txav mus.

Yog tias cov txiaj ntsig zoo ib yam li saum toj no, koj li Base-Collector hlws ris yog Ok

6. Txuas tus neeg sojntsuam mus rau Emitter thiab Collector (kev sojntsuam tuaj yeem hloov pauv), kev nyeem ntawv siab dua 1Kohms qhia tias ua haujlwm transistor.

Kauj Ruam 4: Txheeb Xyuas Qhov Tsis Zoo Transistors

1. Yog tias lawv tsis muaj kev tiv thaiv ntawm ib qho ntawm cov khub thaum kuaj (koob mus txhua txoj kev mus rau sab xis) rau txhua kauj ruam. Lub transistor tau luv.

2. Yog tias rau tag nrho cov kauj ruam, tsis muaj koob txhaj tshuaj tshwm sim, lub transistor tau qhib.
