The SMG5 provides a 1000V voltage source, monitors current, and displays the resistance between the test points. Maximum current output is \u0026lt;1mA. It can be used to determine the condition of insulation from winding to ground in a motor, compressor, or transformer. Includes a case, alligator clip lead tip and leads with removable tips.\u003c\/p\u003e\u003cp\u003eTo test resistance, a DMM supplies low voltage (\u0026lt;1V) to the test points and is capable of delivering only a few milliamps. It's not a high enough voltage to detect high resistance problems that might indicate moisture and other contaminants and it's not enough current to measure lower values of resistance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePredict compressor failure\u003c\/li\u003e\n\u003cli\u003e1000VDC stresses insulation to measure up to 2000Mohms\u003c\/li\u003e\n\u003cli\u003eBacklit LCD display\u003c\/li\u003e\n\u003cli\u003eAuto-off to extend battery life\u003c\/li\u003e\n\u003cli\u003eCase, alligator clip, leads with removable tips\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.fieldpiece.com\/products\/detail\/smg5-digital-megohm-meter\" onclick=\"window.open(this.href, '', 'resizable=no,status=no,location=no,toolbar=no,menubar=no,fullscreen=no,scrollbars=no,dependent=no'); return false;\"\u003eClick here to view the technical specification visit the Fieldpiece website\u003c\/a\u003e\u003c\/p\u003e","brand":"Fieldpiece","offers":[{"title":"Default Title","offer_id":56485873975627,"sku":"SMG5","price":108.93,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0981\/9530\/8875\/files\/fieldpiece-digital-megohmmeter-smg5-17119-p.jpg?v=1770623343","url":"https:\/\/www.ac-one.co.uk\/products\/fieldpiece-digital-megohmmeter-smg5","provider":"Air Conditioning One Ltd","version":"1.0","type":"link"}
