상품 특징

• 선명한 컬러 LCD 디스플레이: 대형 컬러 LCD가 있는 회로 분석기는 배선 결함, AFCI, GFCI, 전압 강하 및 장치 트립 시간에 대한 이해하기 쉬운 결과를 제공합니다
• 종합적인 배선 결함 감지: 표준, AFCI 및 GFCI 전기 콘센트에서 일반적인 배선 결함을 감지하고 식별하여 철저한 평가를 보장합니다
• 이중 배선 결함 감지: 개방형 중립 및 개방 접지를 포함한 이중 배선 결함을 감지하여 안전 조치를 향상시킵니다
• AFCI 및 GFCI 장치 검사: AFCI 및 GFCI 장치를 검사하여 정확한 기능 평가를 위해 트립 시간과 트립 전류를 측정합니다
• 부하 테스트 기능: 12A, 15A 및 20A 부하 테스트를 수행하여 전압 강하 백분율을 측정하여 전기 성능에 대한 귀중한 통찰력을 제공합니다
• 자동 전원 끄기: 5분 동안 사용하지 않으면 자동으로 전원이 꺼져 배터리 수명을 보존하고 장기간 사용할 수 있습니다
• 분리 가능한 코드: 탈착식 코드로 쉽게 보관할 수 있어 회로 분석기를 편리하고 체계적으로 다룰 수 있습니다

• I have one GFCI outlet and no GFCI or AFCI breakers. Given that, I probably didn’t stress the analyzer as much as some of the other reviewers did. I’m also not a practicing electrician, so I haven’t given the unit heavy use. My rating is based on using it only a few times, and it’s something I probably won’t be repeating on a daily basis—so I cannot really comment on reliability.The RT390 greatly simplifies measuring voltage drop by giving results at three different loads—12 A, 15 A, and 20 A—with the press of a button. The results are displayed for five minutes, even if the cable is disconnected, so it’s easy to take the analyzer to a computer to record the results
• I put them into a spreadsheet that does some additional calculations, like estimating the length of the circuit under test.Detachable CableThe detachable cable is handy
• anything with an IEC C13 connector can also be used. The 1’ cable supplied can be a bit short for some applications
• I got 2′ and 3′ 14 AWG cables for some harder-to-reach locations
• you probably could go a bit longer without serious problems. I also got a NEMA 5-15P to IEC C13 adapter (https://www.amazon.com/dp/B0CT7HB42J) for direct plug in and an Ideal 61-183 SureTest® alligator clip adapter (https://www.amazon.com/dp/B000R99RFI) for connections other than receptacles.A Sturdier CaseIt’s nice that Klein provide a case, but unlike most Fluke cases, the case isn’t padded and isn’t very protective—I would not want to drop it. The RT390 costs as much as many multimeters, so it’s worth protecting. To address this, I got a Jinmei EVA hard case (https://www.amazon.com/dp/B0C24N9Z5W).Testing Ungrounded DevicesAs has been noted by some others, the analyzer will not perform any tests with “incorrect” wiring, so out of the box, it cannot be used on ungrounded receptacles or lamp sockets. But it’s simple to work around this if a good ground is available. I have a grounding wire that plugs into a grounded receptacle. I’ve used it to properly ground an antistatic mat
• many of the better antistatic mats include such an adapter. I made mine from an old extension cord, but it could easily be made with green wire and a plug. I
