Conductor Resistance Evaluation System (AMR)

Overview of Equipment

Efficient evaluation of the reliability of connectors

This system enables continuous measurement of micro resistance values of solder joints and conductor parts of connector contacts in low-temperature and high-temperature thermal cycle environments. Automatic measurement, data storage, and data processing are operated systematically with a computer. Featuring data graphs, compatibility with spreadsheet software, and data processing via LAN, this system enables more accurate and efficient connection reliability evaluation.

Features

In pursuit of reliability: Equipped with a measuring instrument and micro resistance meter traceable by international standards, this system pursues reliability of measurement data. It also provides a calibration service to maintain the accuracy and meet your needs. (Complies with ISO/IEC 17025)

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.

Link 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.
