It delivers a maximum test voltage of 1000 VDC and measures insulation resistance up to 4000 megohms. The digital LCD display gives clear, direct readings in the field. Powered by 1.5V AA batteries, it requires no external power source, making it practical for work at panels, motors, cables, and switchgear. Licensed electricians and electrical contractors are the primary users of this instrument.\u003c\/p\u003e\u003cp\u003eThe AMB-45 is suited for residential, commercial, and light industrial electrical work. It carries a CAT III safety rating, appropriate for testing at distribution-level circuits, fixed installation equipment, and building wiring. Common applications include motor winding insulation checks, cable testing after installation, and verifying insulation condition on aging equipment before commissioning or troubleshooting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasures insulation resistance up to 4000 megohms\u003c\/li\u003e\n\u003cli\u003eMaximum test voltage of 1000 VDC\u003c\/li\u003e\n\u003cli\u003eDigital LCD display for direct field readings\u003c\/li\u003e\n\u003cli\u003eCAT III safety rating for distribution-level electrical work\u003c\/li\u003e\n\u003cli\u003eBattery operated with 1.5V AA cells for portable, cord-free use\u003c\/li\u003e\n\u003cli\u003eIncludes alligator clips, batteries, carrying case, test leads, RS-232 cable, software, and instruction manual\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose insulation resistance tester compatible with standard electrical test lead configurations used in commercial and residential electrical service work.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDe-energize and lock out all circuits before connecting the AMB-45 to any wiring or equipment under test. Discharge capacitive loads fully prior to measurement to protect both the instrument and the technician. Installation and insulation testing should be performed by a qualified electrician in accordance with NFPA 70E and applicable NEC requirements. Store the instrument in the included carrying case when not in use to protect the test leads and accessories.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance Capacity\u003c\/strong\u003e: 4000 megohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Test Voltage\u003c\/strong\u003e: 1000 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: Digital LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply\u003c\/strong\u003e: Battery operated (1.5V AA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Category Rating\u003c\/strong\u003e: CAT III\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Alligator clips, batteries, carrying case, instruction manual, RS-232 cable, software, test leads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AMPROBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AMB-45\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AMPROBE","offers":[{"title":"Default Title","offer_id":51538274550066,"sku":"AMB-45","price":1024.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9a9dae3a75f25b32f7f45c81013e01c.jpg?v=1785821413","url":"https:\/\/voomisupply.com\/products\/amprobe-amb-45-insulation-resistance-tester-4000-megohm","provider":"Voomi Supply","version":"1.0","type":"link"}
