Daim ntawv thov tshwj xeeb rau clamp-on ammeters
(1) nyob rau hauv kev ntsuas ntawm tes pinch nruj spanner uas qhib, qhov chaw ntawm lub ntsuas tam sim no-nqa hlau yuav tsum muab tso rau hauv nruab nrab ntawm lub puab tsaig, tiv thaiv kev ntsuas qhov yuam kev, thiab tom qab ntawd tso cov spanner, kom cov tub ntxhais. kaw, lub taub hau meter ntawm cov lus qhia.
(2) Kev ntsuas yuav tsum ua ntej kwv yees qhov loj ntawm qhov ntsuas tam sim no lossis qhov hluav taws xob, xaiv qhov tsim nyog lossis ua ntej xaiv qhov ntsuas qhov loj dua, thiab tom qab ntawd nyob ntawm qhov loj ntawm qhov ntsuas tam sim no thiab qhov hluav taws xob kom txo tau qhov ntau, kom qhov kev nyeem ntawv yog ntau tshaj 1/2 ntawm qhov ntsuas, txhawm rau kom tau txais kev nyeem ntawv ntau dua.
(3) txhawm rau ua kom muaj kev nyeem ntawv kom raug, lub puab tsaig ntawm ob qhov chaw yuav tsum xyuas kom muaj kev sib koom ua ke zoo, xws li suab nrov, lub puab tsaig tuaj yeem rov qhib thiab kaw ib zaug, yog tias lub suab tseem muaj, koj tuaj yeem tshawb xyuas seb puas muaj cov av nyob hauv. sib koom ua ke, yog tias muaj av, tuaj yeem ntxuav nrog roj av.
(4) Thaum ntsuas qhov qis-voltage fusible fuse lossis low-voltage busbar tam sim no, cov theem nyob sib ze yuav tsum tau muab cais los ntawm insulating boards ua ntej ntsuas los tiv thaiv theem-rau-theem luv-circuits uas yuav tshwm sim thaum lub puab tsaig qhib.
(5) Qee cov qauv ntawm clamp ammeter nrog AC voltage scale, ntsuas tam sim no thiab voltage yuav tsum tau nqa tawm nyias, tsis nyob rau tib lub sij hawm.
(6) Tsis tuaj yeem siv rau kev ntsuas high-voltage.
(7) Tom qab kev ntsuas tiav, nco ntsoov muab qhov hloov pauv ntawm qhov siab tshaj plaws tam sim no txoj hauj lwm, kom tsis txhob muaj kev puas tsuaj rau lub cuab yeej thaum nws siv lwm zaus vim qhov ntau yam tsis tau xaiv.
(8) Txhawm rau ntsuas qhov tam sim no tsawg dua 5A tuaj yeem tau txais kev nyeem ntawv ntau dua, nyob rau hauv cov xwm txheej tso cai ob peb zaug ntxiv ntawm cov xaim mus rau lub puab tsaig ntawm qhov ntsuas, tab sis qhov tseeb tam sim no tus nqi yuav tsum tau nyeem rau tus lej faib los ntawm cov tus naj npawb ntawm cov xov hlau rau hauv lub puab tsaig ntawm tus naj npawb ntawm cov hauv paus hniav.
