Lub ntsuas hluav taws xob tiv thaiv muaj qhov ntsuas hluav taws xob siab hloov hluav taws xob tswj hluav taws xob (muaj peev xwm kho qhov ntsuas kev ua haujlwm qhov hluav taws xob xav tau rau cov zis), qhov hluav taws xob ntsuas hluav taws xob tam sim no (muaj peev xwm teeb tsa lub tswb tam sim no) thiab qhov taw qhia qhia lub ntsuas vaj huam sib luag (nyeem cov zis. voltage thiab to tam sim no).Thaum lub sij hawm qhov kev xeem ntawm me me-scale xeem tswj fais fab project, thaum cov khoom kuaj mus txog lub sij hawm yuav tsum tau raws li qhov yuav tsum tau ua hauj lwm voltage, lub portable withstand voltage tester yuav cia li disconnect cov zis voltage;ib zaug nkag tau tshwm sim, uas yog, cov xau tam sim no tshaj qhov teeb tsa lub tswb tam sim no, thiab lub tswb nrov thiab pom kev yuav txuas ntxiv mus.
Kev khiav hauj lwm txheej txheem ntawm portable withstand voltage tester:
1. Thaum nws paub meej tias qhov tso zis hluav taws xob ntawm qhov ntsuas hluav taws xob tiv thaiv hluav taws xob yog "0", Thaum lub teeb ntsuas hluav taws xob "tawm", ntxig ib qho kawg ntawm qhov ntsuas hluav taws xob sib txuas hluav taws xob (ci liab) rau hauv qhov sib xws (AC los yog DC) high-voltage tso zis kawg ntawm qhov kev sim me me tswj lub cev muaj zog tiv thaiv hluav taws xob tester, thiab txuas rau lwm qhov kawg nrog lub zog hloov hluav taws xob nkag kawg lossis lwm yam khoom siv hluav taws xob ntawm cov khoom kuaj.Tom qab ntawd txuas rau lwm qhov kev xeem xaim (grey dub) ib kawg yog muab tso rau hauv cov khoom siv hauv av kawg ntawm lub portable voltage withstand tester thiab clamped nruj nreem, thiab lwm kawg yog txuas nrog lub plhaub (hlau cov khoom) ntawm cov khoom kuaj los yog grounding hlau. kawg ntawm qhov hloov hluav taws xob hloov hluav taws xob kawg (yog tias cov khoom kuaj tau txuas nrog hauv av lossis cov xaim hauv av, cov khoom siv hauv av kawg ntawm cov khoom siv hluav taws xob tiv thaiv yuav tsum tau txuas nrog nws).
2. Nias thiab tuav lub khawm "khiav", "nrhiav" lub teeb pom kev, qhov ntsuas hluav taws xob ua haujlwm yog qhov ntsuas tam sim no ua haujlwm voltage, thiab qhov taw qhia tam sim no to yog tam sim no to tam sim no ntawm cov khoom kuaj.Yog tias cov khoom kuaj tau tsim nyog, lub tswb nrov ntsiag to yuav nrov sai li sai tau thaum lub sij hawm xeem tuaj, thiab tib lub sij hawm, lub portable voltage withstand tester yuav txiav tawm qhov tso zis voltage;Yog hais tias cov khoom kuaj tsis dhau qhov kev xeem nyob rau hauv lub sij hawm xeem, lub teeb "alarm" yog nyob rau, lub passive buzzer ua suab nrov, thiab lub portable withstand voltage tester txiav tawm qhov tso zis voltage.Nias thiab tuav lub khawm "calibration" kom tshem lub tswb.
3. Siv lub davhlau ya nyob twg tswj xyuas cov khoom siv hluav taws xob ua haujlwm (lub "khiav" khawm ntawm lub vaj huam sib luag tswj, khawm "calibration" tsis siv tau, thiab lub pob "rau lub sijhawm" yog muab tso rau ntawm txoj hauj lwm "tawm".
