The earth protects the equipment and personnel from the fault current.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003ePDR302\u003c\/strong\u003e has an earth resistance measuring range of 10\/100\/1000Ω with an accuracy of ± 5 % of full scale for Ω x 1, or ± 2.5% of full scale for Ω x 10, Ω x 100 range. The device can measure a maximum AC leakage voltage of 30 Volts with an accuracy of 2.5% of full scale. The PDR302 also features an auxiliary grounding value LED indicator that lights at approx. 10kΩ or more.\u003c\/p\u003e\n\u003cp\u003eThe earth resistance measurement can be initiated with a simple push button, making the unit easy to use and eliminating wasteful battery consumption.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMeter includes: test leads, clips, earth bars and carrying cases.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePhase detection system circuit for high precision measurement\u003c\/li\u003e\n\u003cli\u003eAC 30V range to avoid indication errors caused by leak current that flows to the earth\u003c\/li\u003e\n\u003cli\u003ePower saving design with push switch\u003c\/li\u003e\n\u003cli\u003eAuxiliary grounding value excess indicator lamp\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left;\"\u003eMeasuring Range\u003c\/th\u003e\n\u003cth style=\"text-align: left;\"\u003eTolerance\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd rowspan=\"2\"\u003eEarth resistance\u003c\/td\u003e\n\u003ctd\u003e10Ω\u003c\/td\u003e\n\u003ctd\u003eWithin ±5% of the max. scale value\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e100\/1000Ω\u003c\/td\u003e\n\u003ctd\u003eWithin ±2.5% of the max. scale value\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eACV\u003c\/td\u003e\n\u003ctd\u003e30V\u003c\/td\u003e\n\u003ctd\u003eWithin ±2.5% of the max. scale value\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGround resistance measuring method\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eRated current measuring method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eR6P(AA battery) 1.5Vx6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\/Mass\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eH175×W118×D55mm\/Approx. 500g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Sanwa","offers":[{"title":"Default Title","offer_id":44911672721632,"sku":"PDR302","price":443.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0356\/8248\/4360\/files\/pdr302-portable-earth-tester-with-phase-detection-pdr302-303889.jpg?v=1752691885","url":"https:\/\/sper-direct.myshopify.com\/products\/pdr302-portable-earth-tester-with-phase-detection","provider":"Sper Scientific Direct","version":"1.0","type":"link"}
