Cov peev txheej ua tau thiab cov kev daws teeb meem ntawm lub siab xa hluav taws xob xa tawm tsawg dhau los yog tsis tsim tawm

(1) Voj tsis ua haujlwm

1. Txheeb xyuas seb hluav taws xob hluav taws xob muaj luv luv Circuit Court, qhib Circuit Court thiab ntau qhov chaw ntawm av.

2. Txheeb xyuas kab txuas txuas polarity thiab voj impedance. Nco ntsoov tias qhov voltage siab tshaj 100V yuav siv tsis tau thaum kuaj lub Circuit Court.

(2) Lub tshuab ua kom lub siab hloov pauv tsis ua haujlwm

1. Kuaj xyuas seb lub raj xa hluav taws xob txuas txuas ntawm lub siab xa cov hluav taws xobUPB2puas yog.

2. Tshawb xyuas rau cov xau thiab blockages.

3. Txheeb xyuas cov nyiaj tso rau hauv cov yeeb nkab siab ua kua.

4. Txheeb xyuas cov nyiaj tso rau hauv qhov flange.

(3) Ua tsis tiav ntawm cov khoom sib txuas hluav taws xob

1. Xyuas seb cov coj ntawm cov khoom sib txawv puas luv-ncig.

2. Txheeb xyuas kom cov txuas txuas kom huv thiab txhim khu kev qha, thiab tshawb xyuas cov xov ntawm cov xaim hluav taws xob kom yooj yim.

3. Txheeb xyuas seb cov pins puas tso siab rau lub khauj khaum.

(4) Kuaj xyuas seb puas yuav kuaj lub diode hlawv

Hloov lub diode lossis luv luv-Circuit Court test davhlau ya nyob twg.

(5) Circuit Board tsis ua hauj lwm

1. Kuaj xyuas qhov tsis zoo ntawm lub rooj tsav xwm ntawm lub siab xa hluav taws xobUPB1nrog cov khoom seem.

2. Hloov lub faulty Circuit Court board.

3. Soj ntsuam cov rhiab Cheebtsam
