Overview

HIOKI ST5680A is a new-generation DC withstand voltage insulation tester launched in 2026, specially customized for full-chain safety testing of EV lithium batteries from single cell to module and pack HIOKI....

Max 8kV high voltage output meets global CE/UKCA/CSA standards, uniform test scheme for overseas production bases. Built-in capacitive contact check avoids false PASS caused by poor probe contact; arc detection captures tiny insulation defects induced by metal burrs or foreign debris. 7-inch touch screen displays real-time voltage/current waveform, stores test data for traceability, standard LAN/USB/EXT I/O interfaces seamlessly connect with automation equipment and CN040 scanning software.

Core Features

1. Dual test modes: DC withstand voltage + insulation resistance, 0.01kV–8kV adjustable output, 1V precision step
2. Ultra-high current resolution 0.001μA, accurately detect micro leakage current of insulation defects
3. Built-in contact check function, no extra auxiliary equipment needed to prevent misjudgment
4. Arc discharge detection, screen hidden insulation failure in advance to avoid defective outflow
5. Intelligent waveform recording (500kS/s sampling), save voltage/current curve for failure analysis
6. Complete global safety certification CE/UKCA/CSA, unified testing standard worldwide
7. Auto fast charge & automatic discharge function, shorten single test cycle to boost line efficiency
8. Interlock safety protection, emergency stop button, multi-group test parameter memory
9. Standard LAN, USB, EXT I/O interfaces, optional RS232/GP-IB for industrial automation linkage
10. 7-inch TFT touch color screen, intuitive operation, support batch test data export
