3. DS-2000 Setup
3-1 Preparing for Setup
To correctly operate the connected impulse hammer and accelerometer and display data,
set operating conditions and sensitivity of the sensor to an FFT analyzer. Sensitivity and
operating condition settings are described in the "Calibration Chart" supplied with the
accelerometer to be used.

Remarks
*The cable capacitance is excluded. However, the cable capacitance is included with the directly connected type.
Set data items of ① and ② on the calibration chart to the FFT.
①
Voltage sensitivity indicates a voltage to be output by the sensor with an acceleration
