High-resolution TFT color display: a clear, easy-to-read screen that presents voltage and resistance readings at a glance, reducing interpretation errors and speeding up inspections. Simplified battery testing: eight preset voltage and resistance settings let you run consistent, repeatable tests quickly — ideal for routine checks and fast troubleshooting of battery faults. Accurate measurements with Kelvin 4-wire technique: the four-wire connection minimizes lead and contact resistance influence, delivering reliable voltage and resistance results for precise diagnostics. Automatic data recording and PC connectivity: all test results are saved automatically and can be transferred to a computer for detailed analysis and reporting, so you keep a complete audit trail and can generate reports when needed. Designed for practical use: intuitive interface and preset modes reduce setup time; the combination of display clarity, measurement accuracy, and logged results improves workflow in maintenance and quality control tasks. Performance and compatibility: optimized for voltage and resistance testing of batteries and related components; connect to a computer to archive data and perform further analysis without manual transcription. Use scenarios Routine maintenance in vehicle fleets: quickly screen batteries using the preset profiles, read results on the color TFT display, and export test logs to a computer for maintenance records and warranty checks. Backup power system checks: perform frequent, consistent resistance and voltage checks on UPS and battery banks; accurate Kelvin 4-wire readings help detect early degradation before failures occur. Manufacturing and quality control: integrate fast, repeatable battery tests into production or incoming inspection processes, store automatic logs for traceability, and transfer results to a computer for batch analysis. What it solves Saves time by simplifying setup and interpretation with presets and a high-contrast color display.
