With optimized filters and protections for measurements in electrical substations.\u003c\/p\u003e\n\u003cp\u003eCan be used to accurately measure very low contact resistances of high voltage circuit-breakers and switches, busbars, etc, with test currents from 5 A up to 200 A. It employs the 4 terminals-method (U\/I measuring principle) to avoid errors caused by test leads and their contact resistances.\u003c\/p\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eMO-589R-200A\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ehas a cooling system that allows making a large number of consecutive tests without activation of thermal protection. Under normal ambient conditions (77 °F | 25 °C) it can perform up to 30 consecutive tests with duration of 1 minute and 1 minute interval, time usually spent for repositioning the cables in another test point. This is a strong but lightweight equipment, and may be easily carried by one person. It is waterresistant and can be used under severe weather conditions (IP65 with closed lid) offering an excellent performance working both in the laboratory and out in the field.\u003c\/p\u003e","brand":"tinsley.co.uk","offers":[{"title":"Default Title","offer_id":57375820513615,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/2088\/5583\/files\/MO-589R-200A.jpg?v=1775046078","url":"https:\/\/tinsley.co.uk\/products\/mo-589r-200a-portable-digital-micro-ohmmeter","provider":"Tinsley Instrumentation Ltd","version":"1.0","type":"link"}
