For ideal measurement data, the result will be the same no matter which method you select.
However, the results obtained by the above four algorithms will differ for actual measurement
data containing noise, measurement errors, and other problems. Select the C

estimation mode
in reference to the equivalent circuit fit results. Usually, “RESNf” should be used.

[FREQ RESOLN]
:
Set frequency resolution for impedance characteristic simulation.

○ Functions of function keys
・
[SWEEP SETTING]
: It will set the same value as the sweep resolution setting value.
・
[EDIT]
: Set the frequency resolution with the numerical input palette.
・
[MODIFY]
: Modify the frequency resolution with the knob or cursor keys.
The impedance characteristic is calculated from the equivalent circuit estimation results and
then displayed in a graph. The impedance characteristic is calculated with a number of
frequency points of the value set here + 1 in the frequency resolution of this time and then
displayed on the graph.

[PZT CONST]:
Calculate the piezoelectric constants.

[[PZT CONSTANT]]
: Display the piezoelectric constant calculation dialog box.
This displays a dialog box to enter information such as the DUT piezoelectric ceramic shape
and vibration mode to calculate various piezoelectric constants.
■ [REL PERMT]:
Set parameters for relative permittivity measurement.
This sets the shape information of the DUT for displaying the relative permittivity of the
DUT. It can be set when the measurement mode is IMPD−EXT, IMPD−3T and IMPD−2T.
When relative permittivity related (ε

[ELECTRODE AREA]:
Set the electrode surface area.
○ Setting procedure

○ Functions of function keys
・
[EDIT]
: Set the electrode surface area (unit: mm

[ELECTRODE DISTANCE]
：
Set the distance between electrodes.
