    • Wire Harness Micro-Interruption Simulator

    The wire harness micro-interruption simulator LMI-216 is based on ISO16750-2 (2023), which can meet the E-10 and E-13 provisions of the VW80000 and LV124 standards. The waveform rise and fall time is 200ns, and meets the test requirements of GMW3172 9.2.18 and 9.2.19. Supports Volkswagen and Audi's latest voltage change rate testing requirements. Supports square wave duty cycle test, and the square wave duty cycle can be set arbitrarily. The power cord supports positive and negative interruptions. The signal line supports single-channel and multiple-channel simultaneous testing, with a maximum of 16 channels, and the channels can be switched.
    According to standards: ISO16750-2(2023), VW80000, LV124, GMW3172, etc.
