Profile:

A human-centric tester with high-frequency switching power supply and digital circuit tech. It offers 4 fixed DC current outputs (50A/100A/150A/200A), 0.01μΩ stable resolution, touchscreen control, data storage, printing and U-disk transfer.

Features:

  1. Large continuous current output effectively breaks through contact oxide films, avoiding drawbacks of pulsed power.
  2. High stability: Last digit stabilizes within ±1 word under severe interference, ensuring repeatable readings.
  3. Ultra-high precision: Dual 16-bit Σ-Δ AD sampling and advanced digital signal processing, achieving 0.01μΩ resolution.
  4. Intelligent: Imported high-performance CPU with auto-range switching and over-temperature protection for safety.
  5. Premium quality: Imported key components, temperature compensation circuit, and military-grade connectors for vibration resistance.
  6. Powerful functions: 4 selectable current gears and 4 test time options (fast/10s/30s/60s), outperforming similar instruments.
  7. User-friendly touchscreen control: Easy date/time setting, real-time data storage and instant printing.
  8. U-disk data transfer: Export data via USB for further analysis with upper computer software.
  9. Portable: Compact size and lightweight design for convenient on-site carrying and use.
