Introduction to Voltage Drop Testing System Details
Function Overview Overview:
1. Voltage drop, contact resistance, and temperature rise are electrical performance evaluation indicators for automotive wire harness connectors in high current and low current circuits
2. Integrated circuits and high-precision chip control
3. Constant current source supply output, LCD display
4. Provide USB and 232 communication interfaces; Can be connected to an external control unit
5. PCSoftware system for analyzing current, time, temperature rise, contact resistance, and voltage drop curves and data models
6. Suitable for providing more reliable data assurance to technical departments such as research institutes, enterprise R&D, incoming inspection, and quality centers
