UNI-T UT3513 Bench Top Micro Ohm Meter

Description

UNI-T UT3513 Bench Top Micro Ohm Meter The UNI-T UT3513 is a bench-top micro-ohm meter designed for precise DC resistance measurement across a broad span (from micro-ohms up to kiloohms). It combines a 4.3-inch display and an ARM microprocessor to provide automated, real-time detection, zero-clearing and self-calibration routines that help ensure repeatable low-resistance readings. The UT3513 supports 4-terminal Kelvin connections (UT-L82 test lead supplied), manual and automatic range selection, manual/auto saving and USB disk storage for test data and screenshots. The instrument offers trigger modes (internal and external/handler/remote), keypad lock, screenshot save via USB, and a handler/communication interface for automated sorting or integration into production lines. Engineered for lab and production use, the UT3513 provides high stability and accuracy for medium- and low-speed measurement modes, quick statistical/logging functions, temperature-compensation support (optional for UT3513), and multiple commas interfaces (RS-232/USB/RS-485). Its compact bench size and handler outputs make it suitable where fast, repeatable low-resistance checks and automated sorting are required. Features: 4.3-inch large LCD display. High-performance ARM microprocessor control and automatic real-time detection. High resolution down to 1 μΩ and measuring range to 20 kΩ (UT3513). Two test speeds (Slow and Medium) with selectable range modes. Zero-clearing (short circuit correction) and self-calibration functions. Temperature compensation support (optional for UT3513). Manual/Auto save and USB disk storage management. Handler interface and comparator output for automated sorting. RS-232, USB (virtual COM), and RS-485 communication interfaces. Keypad lock, screenshot function and non-volatile memory.
