EU Function
EU Function
The CF-7200 FFT analyzer can not only
directly read values as a voltage (V) but
also as a physical quantity. When the
input sensitivity has been set and
calibration with a reference signal
performed for each sensor, waveform
values are converted to physical
quantities when displayed, eliminating
the need to convert from voltage values
to physical quantities.

Average Summation UNDO Function
This function is used during average
summation to UNDO one average
summation. For example, if you end up
with a bad result of summation in
impulse hammer shaking, you can
cancel the result data (by UNDOing the
summation) and then try the summation
again.
Differential and Integral Functions
Differential and Integral Functions
First and second order differential operations and
single and double integral operations are possible
for time-axis and frequency-axis waveforms.
Acceleration data from an acceleration sensor can
be converted to velocity and displacement; and
velocity data from a laser Doppler vibration meter
can be converted to acceleration and displacement
and displayed. When the EU function is used
together, unit conversion (among "m/s
2
", "m/s" and
"m") is also performed automatically.
List Display
This function displays a list of X-axis and Y-axis values for selected points on a
displayed waveform. Numeric list for 40 points selected, peak value list and harmonic list
enable numeric values to be simultaneously checked for multiple points.
