Setting the Test Conditions
Setting the sampling frequency and number of sampling data
Sets the voltage sampling frequency and the number of sampling data to be imported to the
instrument.
SAMPLING
(Sampling frequency)
Sets the voltage sampling frequency.
If a sufficiently long response waveform cannot be imported because
the response waveform vibration period is long, you can extend the
waveform to be imported by extending the sampling frequency.
RECORD LENGTH
(Number of sampling data)
Sets the number of sampling data to be imported to the instrument.
If there are vibration waveform parts that are unnecessary for
judgment at the end of the waveform after the sampling frequency
has been adjusted and the waveform length decided, you can adjust
so as to exclude the unnecessary waveform parts by reducing the
number of sampling data.
AUTO SET
(Automatic settings function for
range of waveform acquisition)
This function automatically adjusts and sets the sampling frequency
and number of sampling data during voltage calibration so that the
waveform acquisition range is optimal.
