Conductor Resistance Evaluation System
Overview of Equipment
Efficient evaluation of the reliability of connectors
This system can continuously measure the micro resistance of conductor parts, such as solder joints and connector contacts, in a temperature cycle environment that cycles between low and high temperatures and is capable of acquiring and processing automated data. By linking with a temperature cycle tester that complies with testing standards, the system enables accurate and efficient connection reliability evaluation.

Features
- Real-time monitoring of temperature
- AMR monitors and records the temp. inside the environmental test chamber.
Data are recorded simultaneously with the measurement carried out by the AMR. The statistics processing software displays the recorded data in synchronization with the data of the resistance tests.
- Direct and alternating electric current measurement systems
- Choose from a direct electric current (AMR-UD) or alternating electric current (AMR-UA) system for measuring micro currents applied to the specimen during conductor resistance measurement.
- Relay unit
- Installation of a relay unit enables easy connection of the measurement cable.
- Integrate with an environmental test chamber to perform monitoring, manage test schedules, and issue alarm warnings.
- Choose from absolute value or rate of change determination for fault determination
- Remote operation of test data (optional)
- Use LAN application software to check the test status and data processing from a remote location.
- Edit and view real-time data with special statistical processing software
