Lub diode zoo li lub tshuab hluav taws xob. Yog hais tias qhov voltage yog siab tshaj ib qho nqi, lub diode yuav coj. Feem ntau silicon diode tig {{0}} ntawm qhov hluav taws xob yog 0.6V. Thiab diodes tsuas tso cai tam sim no mus rau hauv ib qho kev coj.
Thaum kuaj diodes lossis junctions, lub multimeter yuav tsis tsuas yog muab ntau qhov kev nyeem ntawv tab sis kuj tseem tsav cov tam sim no ntau dua 50mA. (saib Table 1)
Thaum ntsuas qhov tsis kam ntawm circuits uas muaj diodes, qhov ntsuas hluav taws xob ntawm DMM yuav qis dua 0.6V, tiv thaiv cov khoom siv lead ua los ntawm kev ua.
Thaum xaiv ib qho kev kuaj diode, qhov ntsuas hluav taws xob tau tsa los xyuas seb qhov ua haujlwm ntawm diode lossis semiconductor siv lead ua.
Qee qhov DMMs muaj qhov ntsuas diode. Qhov kev ua haujlwm no ntsuas thiab qhia txog qhov tseeb voltage poob thoob plaws lub diode. Qhov hluav taws xob poob ntawm qhov sib txuas ntawm silicon yuav tsum tsawg dua 0.7V thaum lub sij hawm sim mus tom ntej, thiab lub Circuit Court yuav qhib thaum lub sij hawm rov qab sim.
Yuav Ua Li Cas Ntsuas Kev Tiv Thaiv
1. Tua lub zog hluav taws xob
2. Xaiv qhov thaiv hluav taws xob
3. Ntxig qhov kev kuaj dub rau hauv COM jack. Ntxig lub liab xeem lead rau hauv qhov kev xeem ntsuas jack
4. Txuas qhov kev ntsuam xyuas cov hmoov txhuas mus rau ob qho kawg ntawm cov khoom siv lossis cov khoom siv hluav taws xob hauv kev sim
