Clamp ammeters tau muab faib ua hom siab thiab tsis tshua muaj hluav taws xob, uas yog siv los ntsuas qhov tam sim no hauv kab yam tsis muaj kev cuam tshuam cov kab. Nws yog siv raws li nram no:
1. Thaum siv lub ntsuas hluav taws xob high-voltage clamp, xyuam xim rau qib voltage ntawm lub clamp-type ammeter, thiab nws yog nruj me ntsis txwv tsis pub siv lub ntsuas hluav taws xob tsawg-voltage clamp-type meter los ntsuas qhov tam sim no ntawm lub voj voog high-voltage. Thaum ntsuas nrog high-voltage clamp meter, nws yuav tsum tau ua los ntawm ob tug neeg. Cov neeg ua haujlwm tsis ua haujlwm yuav tsum tau sau rau hauv daim ntawv ua haujlwm thib ob. Thaum ntsuas, lawv yuav tsum hnav cov hnab looj tes insulating, sawv ntawm cov ntaub qhwv insulating, thiab yuav tsum tsis txhob kov lwm yam khoom siv los tiv thaiv luv luv los yog hauv av.
2. Thaum soj ntsuam lub sijhawm saib, yuav tsum tau them nyiaj tshwj xeeb rau kev tswj kom muaj kev nyab xeeb ntawm lub taub hau thiab qhov chaw nyob. Qhov kev ncua deb ntawm ib feem ntawm tib neeg lub cev thiab lub cev nyob yuav tsum tsis txhob tsawg tshaj li qhov ntev ntawm lub clamp meter.
3. Thaum ntsuas nyob rau hauv high-voltage Circuit Court, nws yog txwv tsis pub siv ib tug hlau los txuas lub 'meter' mus rau lwm lub 'meter' los ntawm lub clamp-hom ammeter. Thaum ntsuas qhov tam sim no ntawm txhua theem ntawm high-voltage cable, qhov kev ncua deb ntawm lub taub hau cable yuav tsum ntau tshaj 300mm, thiab cov rwb thaiv tsev yuav tsum zoo.
4. Thaum ntsuas qhov tam sim no ntawm cov hluav taws xob tsis tshua muaj hluav taws xob fusible fuses lossis kab rov tav txheej txheem low-voltage busbars, txhua theem ntawm fusible fuses lossis busbars yuav tsum tau tiv thaiv thiab cais nrog cov ntaub ntawv insulating ua ntej ntsuas kom tsis txhob luv luv Circuit Court ntawm theem.
5. Thaum ib theem ntawm lub cable yog grounded, ntsuas yog nruj me ntsis txwv tsis pub. Tiv thaiv kev nyab xeeb ntawm tus kheej los ntawm kev puas tsuaj rau tus kheej kev nyab xeeb vim qhov tsis muaj rwb thaiv tsev ntawm lub taub hau cable thiab qhov tshwm sim ntawm kev tawg hauv av.
6. Tom qab ntsuas lub clamp ammeter, rub lub hloov mus rau qhov siab tshaj plaws kom tsis txhob muaj kev sib tsoo overcurrent thaum siv lwm zaus; nws yuav tsum tau muab cia rau hauv ib chav qhuav.
