High-Precision Measurement Technology

TR518 II (TR518 SII) uses advanced 6-wire measurement switching matrix to eliminate fixture contact resistance error, achieving precise measurement for resistors, capacitors and inductors. It supports multiple programmable test frequencies, stray capacitance offset and phase separation RLC measurement for stable and repeatable readings. The Windows 10 operating system and intuitive graphical board view allow engineers to quickly locate faults and shorten test program debugging time.


Advanced Test & Analysis

Powered by TRI proprietary test software, TR518 II supports automatic test learning, multi-panel program generation and yield management system integration. Typical capabilities include: TestJet vectorless open test, automatic program learning, electrolytic capacitor polarity inspection, stray capacitance compensation, SPC logging, yield analysis & custom reporting.

Optional inline SMEMA version is available for direct integration into fully automated SMT production lines without compressed air requirement.


Fixture & Operation

Supports offline press-type fixture and optional inline conveyor fixture. Modular test point expansion, scalable from 512 points up to maximum 2560 analog test points. Compact cabinet design saves factory floor space, easy maintenance and fast fixture changeover.
