• Best used in production lines
  • Measurement COM port is isolated from digital ground
    for supply, COM ports, and USB connection
  • Capable of conducting test with DC voltage, AC voltage, DC Current, AC Current, measurement of every resistance, diode, etc.
  • Three levels of measurement sampling speeds
  • May be used as test controller:
    Use the included application, FxAutoTest.exe, to edit and write the test program
    to the module, which use the FX-300 and FX-600/620 as a test step.
    Select a test program and run from external I/O interface.


FX-300 Module Panel

The FX-300 is capable of controlling the FX-600/620 relay module from the FX-300 Autotest utility (optional).
