LS5560 High-Voltage Battery Internal Resistance Tester

The LS5560 high-voltage, high-precision battery internal resistance tester is a specialized instrument engineered for comprehensive battery testing applications. It implements an AC 4-terminal measurement methodology to simultaneously quantify battery internal resistance and terminal voltage with exceptional accuracy.

The instrument features a high-resolution color LCD display for clear visualization of test parameters and results. A test lead contact verification function ensures measurement integrity by detecting poor connections. Multiple communication interfaces, including RS232 and optional RS485, support SCPI and Modbus (RTU) protocols for seamless integration into automated test systems and production lines.

With a maximum test rate of 100 measurements per second, 10-level comparator sorting, and HANDLER interface compatibility, this tester is optimized for high-throughput applications such as battery pack assembly verification and production line quality control. Test conditions are automatically preserved across 50 configuration profiles.
