Key features
- Low-Resistance Measurement Optimized for Welding Quality Inspection in Battery Pack/Module Manufacturing Lines
- Ultra-high precision measurement with 1 nΩ resolution to detect small changes in weld quality
- Active Circuit Protection (up to DC 60 V) safeguards the measuring instrument from miswiring and incorrect contact
- The A-TC function enables stable measurement even immediately after welding when temperatures are high, contributing to reduced takt time
- The A-OVC function ensures measurement stability even in environments with large temperature variations
- Increased Freedom in Cable Extension and Equipment Layout thanks to a maximum path resistance tolerance of 9Ω.* *Conditions: PR1000 µΩ, 500 mA, SOURCE B–SOURCE A
