Metrel 產線測試(EOL)機台核心的中央控制單元是MI 3394 CE MultiTesterXS。 顧名思義，它是從MI 3394 CE MultiTester主體衍生而來，並且幾乎共享所有主要功能（下面將詳細介紹）。 但仍具有幾項新功能，包括等電位連接端子和用於連接安全模組的端子…。
Main features：
- Control of measuring circuits with integrated safety modules (NEW).
- Limitation of current in HV testing to safe level in combination with safety module (NEW).
- Electrical safety testing in accordance with EN 50191 (NEW).
- Over 20 different measurements and tests.
- AUTO SEQUENCEs: automated test sequences, which can be remotely driven via black-box protocol.
- Support for integration with other SW systems
- Large memory space
- Versatile PC software (Metrel ES Manager).
- RS-232, USB, Ethernet and Bluetooth communication ports.
- Support for scanners and printers.
Supported tests and measurements：
Visual & functional inspections (user defined inspections can be defined in MESM PC software).
