Wenner\/Schlumberger soil resistivity, 2-clamp ground and DC bond resistance tests round out the measurement set.\u003c\/p\u003e\n\u003cp\u003eThe Model 6474 GroundFlex field kit adds impedance analysis from 41 Hz to 5 kHz on transmission towers. Its flexible sensors clamp around tower legs and pierce insulators so the tower leg can be tested while energized, rejecting interference up to 60 V peak. An optically isolated USB link and 512-measurement memory work with AEMC DataView software for reporting.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4-point fall-of-potential: 0.011 Ω to 99.99 kΩ, auto-ranging\u003c\/li\u003e\n\u003cli\u003eTest voltage 10\/16\/32\/60 V; test frequencies 41 to 5078 Hz\u003c\/li\u003e\n\u003cli\u003eSoil resistivity (Wenner\/Schlumberger), ρ max 999 kΩm\u003c\/li\u003e\n\u003cli\u003eGroundFlex 6474: energized tower testing, 41 Hz to 5 kHz\u003c\/li\u003e\n\u003cli\u003eInterference rejection to 60 V peak\u003c\/li\u003e\n\u003cli\u003e512-measurement memory; USB 2.0 optically isolated with DataView\u003c\/li\u003e\n\u003cli\u003e9.6 V rechargeable NiMH battery, about 1500 tests per charge\u003c\/li\u003e\n\u003cli\u003eIEC\/EN 61557, 50 V CAT IV, IP53\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTransmission tower grounding assessment\u003c\/li\u003e\n\u003cli\u003eLightning protection and grounding system verification\u003c\/li\u003e\n\u003cli\u003eSoil resistivity surveys and substation bonding checks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAEMC 6472 6474 KIT Ground Resistance Tester Technical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003e4-point earth resistance range\u003c\/th\u003e\n\u003ctd\u003e0.011 Ω to 99.99 kΩ, auto-ranging\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e4-point accuracy\u003c\/th\u003e\n\u003ctd\u003e±(2% rdg + 1 ct)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTest voltage \/ frequency\u003c\/th\u003e\n\u003ctd\u003e10, 16, 32 or 60 V; 41 to 5078 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTest current\u003c\/th\u003e\n\u003ctd\u003eUp to 250 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSoil resistivity\u003c\/th\u003e\n\u003ctd\u003e4-point Wenner\/Schlumberger, ρ max 999 kΩm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e2-clamp ground measurement\u003c\/th\u003e\n\u003ctd\u003e0.1 to 500 Ω, auto 1611 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDC bond resistance\u003c\/th\u003e\n\u003ctd\u003e2-pole 0.12 Ω to 99.9 kΩ; 4-pole 0.020 Ω to 99.99 kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGroundFlex impedance analysis\u003c\/th\u003e\n\u003ctd\u003e41 Hz to 5 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMemory\u003c\/th\u003e\n\u003ctd\u003e512 measurements\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCommunication\u003c\/th\u003e\n\u003ctd\u003eUSB 2.0 optically isolated, DataView software\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e9.6 V rechargeable NiMH, about 1500 tests\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions \/ weight\u003c\/th\u003e\n\u003ctd\u003e272 × 248 × 130 mm; 3.2 kg with battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSafety \/ rating\u003c\/th\u003e\n\u003ctd\u003eIEC\/EN 61557, 50 V CAT IV, IP53\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eManufacturer information: \u003ca href=\"https:\/\/aemc.com\/products\/lightning-protection\/ground-tester-6472-1422\" target=\"_blank\" rel=\"noopener\"\u003eModel 6472 on aemc.com\u003c\/a\u003e.\u003c\/p\u003e","brand":"AEMC","offers":[{"title":"Default Title","offer_id":67777127350459,"sku":"IMM_33928942","price":6702.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/aemc-6472-6474-kit.gif?v=1792556854","url":"https:\/\/na.indomultimeter.net\/products\/aemc-6472-6474-kit-ground-resistance-tester-for-tower-grounding-assessments-with-groundflex","provider":"Indo Multimeter","version":"1.0","type":"link"}
