** Kauj ruam 3 - Kuaj **
1. Pib ntawm ** xoom voltage **.
2. Nce voltage maj mam ntawm kev tswj hwm kev tswj hwm.
3. Saib xyuas kom yooj yim tam sim no thiab weugmform ruaj khov.
4. Mus txog qhov kev xeem voltage (feem ntau yog 1.5 × -2 × kev ntsuas hluav taws xob lossis ib qho).
5. Tuav rau lub sijhawm teev tseg (feem ntau 1 feeb rau lub Hoobkas ua haujlwm ib txwm, txog 30-60 feeb rau ntev {4 4}} xyoo kuaj).
6. Saib xyuas kom tawg los yog leakage ntau.
** Kauj Ruam 4 - Kaw **
* Txo voltage du rau xoom.
* Disconnect lub siab - voltage ua.
* Av thiab tawm cov khoom xeem ua ntej kov.
