Siv lub multimeter thiab megohmmeter los xyuas seb qhov rov qab conduction thyristor puas zoo lossis phem

Siv lub multimeter thiab megohmmeter los xyuas seb qhov rov qab conduction thyristor puas zoo lossis phem. Cov ntsiab lus xeem feem ntau muab faib ua peb yam:

1. xyuas retrograde

Xaiv qhov R × 1 ntau ntawm multimeter, txuas cov kev sim dub coj mus rau K ncej, thiab qhov kev sim liab ua rau A ncej. Tus nqi kuj yuav tsum yog 5 ~ 10Ω. Yog tias qhov tsis kam yog xoom, nws ua pov thawj tias lub diode sab hauv yog luv luv; Yog hais tias qhov tsis kam yog infinite, nws txhais tau hais tias lub diode qhib.

2. Ntsuas qhov pem hauv ntej DC breakover voltage V (BO)

Tom qab txuas lub voj voog, co lub megohmmeter ntawm qhov ntsuas ceev kom RCT tawg nyob rau hauv cov kev taw qhia pem hauv ntej, thiab nyeem V (BO) tus nqi los ntawm DC voltmeter.

3. Txheeb xyuas qhov muaj peev xwm ua tau
