Vibration / Shock Testing / Calibration System

The YMC VCS-02 shock testing system consists of the YMC 9204H vibration / shock measuring instrument and YMC 9800-05 software. The 9204H has built-in 4-channel charge amplifiers and IEPE signal conditioners and can input 4 channels of charge, voltage or IEPE sensor signal at the same time, connected to the computer over USB 2.0. Built-in 2-channel DA signal output generates half sine, trapezoidal wave, after-peak sawtooth wave and pulse signal. Multi I/O can control and detect the shock table. It displays working state, measured acceleration value, pulse width, velocity variation and measurement error in real time, and finishes the test report automatically. It supports national, MIL and custom standards, and applies to all kinds of shock test, drop test, impact test and vibration / shock test.
