It supports test voltages of 100 V, 250 V, 500 V, and 1000 V, allowing you to adapt easily to different systems and environments.\u003c\/p\u003e\u003cp\u003eThe device measures insulation resistance from 0.1 MΩ to 10 GΩ, giving you the flexibility required for both routine checks and more demanding applications. Its graphical display with backlighting provides clarity during testing, and the built-in safety alerts help you stay aware of high-voltage conditions.\u003c\/p\u003e\u003cp\u003eAccuracy remains consistent thanks to carefully engineered measurement ranges. Resistance from 100 kΩ to 100 MΩ maintains precision within ± (3% + 5), while readings above 100 MΩ achieve ± (5% + 5). This allows you to trust each result even when working on sensitive electrical installations.\u003c\/p\u003e\u003cp\u003eThe open circuit voltage reaches the test voltage plus 20%, and the meter uses a controlled test current between 1 mA and 1.2 mA depending on the selected level. For short-circuit situations, it delivers approximately 2 mA, maintaining safe operating parameters.\u003c\/p\u003e\u003cp\u003eBeyond insulation testing, it also measures both AC and DC voltage. AC ranges from 30 V to 750 V with ± (2% + 3) accuracy at 1 V, while DC voltage spans 30 V to 1000 V with similar precision. Automatic range switching reduces manual adjustments, helping you complete tasks more quickly.\u003c\/p\u003e\u003cp\u003eConnectivity is straightforward thanks to its RS-232 and USB interfaces, making it easy to transfer results. You can store up to 18 measurements internally, which is useful when documenting tests on multiple circuits or locations.\u003c\/p\u003e\u003cp\u003eThe meter includes several practical features such as comparative testing, polarization index measurement, and a maximum test duration of 30 minutes. Its sturdy and compact build enhances portability, while the large LCD ensures visibility. A low-battery alert helps you avoid interruptions mid-task.\u003c\/p\u003e\u003cp\u003eDesigned to operate reliably between 0 °C and 40 °C with up to 85% relative humidity (non-condensing), this model performs well in typical work environments. It can run on eight 1.5 V R14\/LR14 batteries or an optional 15 V DC adapter.\u003c\/p\u003e\u003cp\u003eWith dimensions of 202 × 155 × 91 mm and a weight of 0.92 kg, it fits comfortably into tool kits. The package measures 330 × 315 × 120 mm and weighs 3.18 kg, offering generous protection during transport.\u003c\/p\u003e\u003cp\u003eThis instrument is well-suited for electricians and maintenance personnel who require reliable insulation testing across a range of electrical systems. Its thoughtful design helps reduce downtime and improve workflow efficiency on the job.\u003c\/p\u003e\u003cp\u003eWatch the product in action on \u003ca href=\"https:\/\/www.youtube.com\/watch?v=example\"\u003eYouTube\u003c\/a\u003e to see how it performs in real testing scenarios.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUpgrade your testing tools today and bring higher confidence to every electrical inspection.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Spy-shop.com","offers":[{"title":"Default Title","offer_id":50457371541834,"sku":"SKU_1741795433485_467","price":186.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/5980\/2954\/files\/uni-t-ut-511-insulation-resistance-meter-for-precise-electrical-testing-default-title-rLL.jpg?v=1770489878","url":"https:\/\/spy-shop.com\/products\/uni-t-ut-511-insulation-resistance-meter","provider":"Spy-shop.com","version":"1.0","type":"link"}
