█  Wide input power voltage(1AC 100～240V),respond to any occasion.
█  Can use all kinds of pulse displacement sensor.
█  Dynamic display process of pressurized electrode displacement graph and the
    dynamic displacement value.
█  Display the average RMS and peak values and welding time
█  At any time prior to the measurement of the displacement can be set  "zero."
█  To determine and display of displacement on the lower / high limit, and output signal
    NG. used in welding quality management.
█  Can set up multiple limit point, to judge, and then output prompt signal, can be used
    for real-time electricity control of welding machine.
