Auto-ranging selects the optimum measurement range and test current automatically, and a large backlit LCD shows results with LED warnings for high input noise, high auxiliary rod resistance and fault connections. The 128 Hz square-wave test signal and filtering let the instrument reject stray currents and harmonics that would otherwise corrupt readings.\u003c\/p\u003e\u003cp\u003eThe KIT-500FT configuration (catalog 2135.24) adds the 4-point test kit: two 500 ft color-coded leads on spools, two 100 ft leads, one 30 ft lead, a pair of 5 ft leads, four 14.5 in T-shaped auxiliary electrodes, five spaded lugs, a 100 ft tape measure and a carrying bag. The tester is powered by a 9.6 V NiMH rechargeable pack with a built-in charger that allows testing while recharging, and the rugged dustproof, rainproof case is rated IP65 when closed.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGround resistance and soil resistivity measurements from 0 to 2000 Ohm\u003c\/li\u003e\n\u003cli\u003e2-point, 3-point fall-of-potential and 4-point Wenner methods\u003c\/li\u003e\n\u003cli\u003eStep voltage and touch potential testing\u003c\/li\u003e\n\u003cli\u003eAuto-ranging with 0.01 to 1 Ohm resolution\u003c\/li\u003e\n\u003cli\u003eHigh interference rejection for DC, 50\/60 Hz and harmonics\u003c\/li\u003e\n\u003cli\u003e9.6 V NiMH rechargeable battery, about 4500 fifteen-second tests per charge\u003c\/li\u003e\n\u003cli\u003eIP65 sealed case (IP63 with lid open) and fuse protection above 250 V\u003c\/li\u003e\n\u003cli\u003eLED indicators for noise, auxiliary rod resistance and faults\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGround rod and grid resistance verification at substations and towers\u003c\/li\u003e\n\u003cli\u003eSoil resistivity surveys for new grounding system design\u003c\/li\u003e\n\u003cli\u003eGrounding checks on lightning protection, telecom sites and swimming pools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGround Resistance Tester Model 4630\u003c\/li\u003e\n\u003cli\u003eTwo 500 ft color-coded leads on spools (red\/blue)\u003c\/li\u003e\n\u003cli\u003eTwo 100 ft color-coded leads (green\/black), one 30 ft green lead, two 5 ft leads (red\/blue)\u003c\/li\u003e\n\u003cli\u003eFour 14.5 in T-shaped auxiliary ground electrodes\u003c\/li\u003e\n\u003cli\u003eSet of five spaded lugs and a 100 ft tape measure\u003c\/li\u003e\n\u003cli\u003eCarrying bag, rechargeable battery, AC power cord and user manual\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAEMC 4630 KIT-500FT Ground Resistance Tester Technical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eMeasurement Range (auto-ranging)\u003c\/th\u003e\n\u003ctd\u003e0 to 2000 Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd\u003e0.01 Ohm (20 Ohm range) to 1 Ohm (2000 Ohm range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTest Current\u003c\/th\u003e\n\u003ctd\u003e0.1 to 10 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTest Frequency\u003c\/th\u003e\n\u003ctd\u003e128 Hz square wave\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy (typical)\u003c\/th\u003e\n\u003ctd\u003ePlus\/minus (2% of reading + 1 count)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOpen Circuit Voltage\u003c\/th\u003e\n\u003ctd\u003e42 V peak\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWithstanding Voltage\u003c\/th\u003e\n\u003ctd\u003e250 VAC or 100 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDisplay\u003c\/th\u003e\n\u003ctd\u003e200-count, 7-segment LCD with backlight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Source\u003c\/th\u003e\n\u003ctd\u003e9.6 V NiMH rechargeable pack; 120\/230 V 50\/60 Hz charger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBattery Life\u003c\/th\u003e\n\u003ctd\u003e4500 fifteen-second tests, low-battery indicator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating Temperature\u003c\/th\u003e\n\u003ctd\u003e14 to 131°F (-10 to 55°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIngress Protection\u003c\/th\u003e\n\u003ctd\u003eIP65 closed; IP63 open\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSafety Compliance\u003c\/th\u003e\n\u003ctd\u003eEN 61557, EN 61010-1, 30 V CAT III, Pollution Degree 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions \/ Weight\u003c\/th\u003e\n\u003ctd\u003e10.8 x 9.7 x 5.0 in (273 x 247 x 127 mm); 7.38 lb (3.35 kg) with battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eManufacturer information: \u003ca href=\"https:\/\/aemc.com\/products\/ground-testers\/ground-tester-4630\" target=\"_blank\" rel=\"noopener\"\u003eAEMC Ground Resistance Tester Model 4630\u003c\/a\u003e\u003c\/p\u003e","brand":"AEMC","offers":[{"title":"Default Title","offer_id":67776213909691,"sku":"IMM_63787513","price":1316.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/aemc-4630-kit-500ft.jpg?v=1792552125","url":"https:\/\/na.indomultimeter.net\/products\/aemc-4630-kit-500ft-ground-resistance-tester-0-to-2000-ohm-4-point-soil-resistivity-kit","provider":"Indo Multimeter","version":"1.0","type":"link"}
