Yuav ua li cas kom paub qhov hluav taws xob to ntawm hluav taws xob soldering hlau?
Ua ntej kho lub multimeter mus rau AC voltage iav, txuas cov kev sim dub coj mus rau hauv av, thiab txuas cov kev sim liab coj mus rau qhov kawg ntawm cov hluav taws xob hlau, thiab saib seb lub multimeter puas muaj kev nyeem ntawv. Yog tias muaj kev nyeem ntawv, nws ua pov thawj tias cov hluav taws xob soldering hlau tau xau thiab yuav tsum tau kho
Disassemble cov hluav taws xob soldering hlau, nrhiav lub hauv paus hauv av, thiab tom qab ntawd nrhiav cov resistor txuas nrog lub rooj tsav xwm hauv Circuit Court raws cov xaim hauv av, thiab ntsuas nws cov nqi tiv thaiv. Yog tias nws siab tshaj 5 ohms, nws raug txiav txim siab kom hlawv thiab yuav tsum tau hloov pauv (feem ntau ntawm cov dej xau Lub resistor hauv qab no puas lawm), thiab yog tias tus nqi kuj zoo li qub, thov paub meej tias qhov kev sib cuag ntawm cov hlau txuas yog qhov zoo.
Tshem tawm qhov hluav taws kub resistor thiab hloov nws nrog ib qho tshiab. Nco ntsoov tias txawm hais tias tus nqi tsis kam ntawm qhov resistor yog 0 ohms, nws yog rau kev tiv thaiv. Tsis txhob luv luv ntawm no!
Tom qab hloov, siv lub multimeter kom paub meej tias qhov kev tiv thaiv tus nqi ntawm qhov chaw taws teeb ntsuas ntawm qhov tsis kam thiab hauv av
