Accroding to the change of characteristics of the testpiece, automatic switching function for testing control works from constant amplitude control to constant load control.

Frequency characteristics range is wide as 0.01 to 100Hz.

Frequency measuring points are many as 137.

Vibration amplitude is available in the ranges of ±4~±160µm(01FP), ±8~±250µm(25FP) and±500µm(*25FP as optional)

Plenty optional function such as various testing jigs, piezoelectricity measurement, stress/ relaxation measurement and creep testing

Software for application of optional items such as mater curve, activated energy, Tg (tanδ) automatic/manual detection and Tg (E') manual detection.

Set-up for the most suitable testing condition by pretension function is possible.

FP series offer much information with substantial function

Assortment of vibration mode & temperature control (both for 01FP & 25FP)
Vibration mode/ measurement	Temperature dispersion	Frequency dispersion	Age-based characteristics	Strain dispersion

Applicable to research/ development and quality inspection for temperature-dependence (-150 degree Celsius ~ + 400 degree Celsius), cycle dependence (0.01 ~ 110Hz), amplitude-dependence of heat-resisting material and sound absorbing material.

DDV-FP series is a dynamic viscoelasticity measuring system with non-resonance forced vibration method and consists of measurement operation block, high/low constant temperature chamber, main unit, power unit (for 25FP), data processing device and various testing jigs (optional items).
Applying the most suitable tension to one end of a loaded testpiece with automatic tension function, and adding the dynamic displacement like sin wave vibaration Ao sin Ωt (sinusoidal stress) as a forced power, detects dynamic load appeared on the other end of the testpiece. By processing tosignal and computing the dynamic strain anddynamic stress, measures complex modulus of elasticity E*, dynamic modulus of elasticy E', loss modulus of elasticity E'' and loss tangent tanδas dynamic mechanical characteristics of the testpiece. Furthe, changing condition under atmosphere environmental condition, tests and outputs the data to the CRT display at the same tiem.
