Waveform Distortion Correction Function The loading waveform is tracked to ensure consistency with the target waveform.

Because it can correct for loading mechanism-speci c periodic strain, it can
cancel out unwanted strain components and accurately control loads according
to the target waveform.

Broad Applicability
Up to four testing machines can be operated for synchronous testing. X-T, X-Y, peak graphs, and a variety of other waveforms can be displayed. By connecting to a
computer via a USB cable, a wide variety of test settings and sophisticated data acquisition settings can be speci ed.

Multiple Tests Synchronized Testing
A single computer can be used to simultaneously perform up to four different Control and measurements of up to four testing machines can be synchronized EMT/NJ-SERVO/MMT Series Electric Fatigue and Endurance Test System
