UT511 insulation resistance meter

Uni-T UT511 Insulation Resistance Tester The Uni-T UT511 insulation resistance tester is a professional tool designed for precise insulation resistance measurement in electrical installations. With advanced features and high accuracy, the UT511 is an ideal choice for electricians, engineers, and specialists involved in maintenance and diagnostics. Precise insulation resistance measurements The UT511 offers a wide range of insulation resistance measurements at four different test voltages: 100 V, 250 V, 500 V, and 1000 V. Measurement ranges cover from 0.1 MΩ to 10 GΩ with an accuracy of ±(3%+5) for lower ranges and ±(5%+5) for higher values, ensuring reliable and precise results. The test current ranges from 1 mA to 1.2 mA, with a short-circuit current below 2 mA, guaranteeing safety and reliability. Versatile measurement functions Besides insulation resistance, the UT511 measures DC voltage from 30 V to 1000 V and AC voltage up to 750 V with an accuracy of ±(2%+3). It also supports low resistance measurement from 0.1 Ω to 999.9 Ω, making it a versatile tool for insulation and other electrical parameter analysis. Diagnostic functions and safety The UT511 includes diagnostic features such as dielectric absorption test, polarization index, and comparative function for comprehensive insulation assessment. It also has automatic range switching, low battery indicator, and high voltage warning, enhancing safety and usability. The backlit LCD screen (123 x 58 mm) and 30-segment analog bar graph facilitate reading results in various lighting conditions. Robust construction and mobility The UT511 is powered by eight 1.5 V (LR14) batteries, providing long operating time, with an auto power-off feature to save energy. Compact dimensions (202 x 155 x 94 mm) and weight of 1.2 kg make it portable and convenient for daily use. The set includes three test leads with crocodile clips, batteries, and a carrying case, enabling immediate use after unpacking.
