1. Xav txog kev siv ib puag ncig ntawm lub hnub ci hluav taws xob hauv tsev thiab lub hnub ci hluav taws xob hauv zos, thiab lwm yam;
2. Lub zog tag nrho yuav tsum tau nqa los ntawm tsev neeg lub zog tsim hluav taws xob thiab lub sijhawm ua haujlwm ntawm cov khoom thauj txhua hnub;
3. Xav txog qhov tso zis voltage ntawm qhov system thiab saib seb nws puas haum rau dc lossis ac;
4. Nyob rau hauv cov huab cua los nag tsis muaj hnub ci, lub kaw lus yuav tsum muab lub zog txuas ntxiv rau ob peb hnub;
5. Kev siv lub zog tsim hluav taws xob hauv tsev kuj yuav tsum tau xav txog kev thauj khoom ntawm cov khoom siv hauv tsev, txawm tias cov khoom siv yog cov tsis muaj zog, capacitance los yog inductive, lub amperage ntawm instantaneous pib tam sim no thiab lwm yam.
