Lub Fallage Tester muaj kev tiv thaiv siab hloov hluav taws xob kev tswj hwm hluav taws xob (muaj peev xwm kev tshuaj xyuas kev ntsuas ua haujlwm), muaj peev xwm soj ntsuam lub tswb ua haujlwm ( Kev sib zog thiab cov toppage tam sim no tam sim ntawd). Thaum kuaj cov ntsuas ntsuas me me tswj lub zog hluav taws xob, thaum cov khoom siv tshuaj ntsuam xyuas lub sijhawm uas yuav tsum tau ua haujlwm rau kev ntsuas ua haujlwm yuav txiav tawm cov zis hluav taws xob; Thaum kev nkag mus tshwm sim, uas yog, qhov to taub tam sim no tshaj lub teeb lub tswb tam sim no, thiab lub suab nrov audible yuav xa mus ntxiv.
Cov txheej txheem kev ua haujlwm ntawm portable withstor voltage kuaj:
1 lossis DC) Cov zis ntau heev ntawm qhov ntsuas me me ntawm kev ntsuas me me nrog lub tshuab Voltage waterging xaus lossis lwm yam energized cov khoom siv ntawm cov khoom sim. Tom qab ntawd txuas rau lwm qhov kev kuaj hlau (txho xim dub) ib qho kawg yog ntxig rau hauv lub tshuab hluav taws xob qhib nrog lub plhaub (cov khoom siv hlau) ntawm cov xaim hluav taws xob lossis cov xaim hluav taws xob) Qhov kawg ntawm hloov lub zog tawm tswv yim xaus (yog tias cov khoom ntsuas tau txuas nrog hauv av lossis kob xaim hluav taws xob, cov khoom siv voltorage yuav tsum tau txuas nrog nws).
2. Nias thiab tuav lub "Khiav" khawm, "Kev Ntsuas Lub Teeb Hluav Taws Xob Ua Haujlwm yog qhov tseeb tam sim no ua haujlwm yog qhov tam sim no ntawm cov khoom kuaj. Yog tias cov khoom sim tsim nyog, lub teeb ci muag yuav suab sai li sai tau, thiab tib lub sijhawm, lub chaw ntsuas hluav taws xob yuav cia li kaw cov ntawv tso tawm; Yog tias cov kwv sim tsis xeem dhau ntawm lub sijhawm xeem, "tswb" lub teeb Nias thiab tuav lub "calibration" kom tshem lub tswb.
3. Siv cov hlau tswj lub davhlau ya nyob twg txhawm rau ntes cov haujlwm voltage resistance ("calibration" khawm tsis raug, thiab lub sijhawm "nyob rau ntawm" off ".
