Yuav siv lub clamp meter li cas kom zoo
(1) Ua ntej kev ntsuas, kev kho tshuab xoom yog tsim nyog.
(2) Xaiv qhov tsim nyog, xaiv qhov dav ua ntej, tom qab ntawd qhov me me, lossis siv daim ntawv teev npe tus nqi raws li kev qhia.
(3) Kev ntsuas yog sib npaug ntawm cov nqi teev sib npaug los ntawm qhov sib faib los ntawm cov lej sib tw twisted nyob ib ncig ntawm lub ntsuas hlau nyob hauv nruab nrab ntawm lub puab tsaig thaum qhov tsawg kawg nkaus yog ua haujlwm los ntsuas thiab kev nyeem ntawv tsis muaj txiaj ntsig.
(4) Kev hloov pauv hloov yuav tsum tau teeb tsa rau qhov siab tshaj plaws thaum ntsuas tiav.
(5) Txhawm rau txo qhov tsis raug, lub puab tsaig yuav tsum tau kaw kom nruj thiab cov xaim ntsuas yuav tsum nyob nruab nrab ntawm qhov qhib.
Kev nyab xeeb ntsuas rau clamp meters
(1) Qhov ntsuas hluav taws xob ntawm txoj kab raug kuaj yuav tsum qis dua qhov ntsuas qhov ntsuas hluav taws xob.
(2) Muab cov hnab looj tes insulating, insulating khau, thiab sawv ntsug ntawm ib qho insulating ncoo thaum ntsuas qhov tam sim no ntawm cov xaim hluav taws xob siab.
(3) Lub puab tsaig yuav tsum raug kaw kom ruaj khov, thiab lub zog yuav tsum tsis txhob muab tua thaum lub sijhawm hloov pauv.
