Operation Modes
Measurement range
The measurable frequency range and measurement upper and lower limits
depend on the accelerometer in use and the measurement mode.
If the overload indicator LED lights up, the measurement upper limit is be-
ing exceeded.
Frequency range
The frequency range for measurement depends on the measurement mode,
as listed below.
Measurement mode and measurement frequency range
Acceleration (m/s

)
1 Hz to 15 kHz (±5%)
0.5 Hz to 30 kHz (±10%)
Velocity (mm/s)
3 Hz to 3 kHz (±5%)
Displacement (mm)
3 Hz to 500 Hz (±10%)
Measurement upper limit
The upper limit for acceleration measurement (maximum input acceleration)
depends on the input sensitivity setting.
• When using the PICKUP connector
Measurement up to 10 times* the maximum range can be carried out.
* Depends to a certain extent on display characteristics.

• When using the PICKUP connector on the panel
The maximum input acceleration depends on the connected preampli-
fi er. The maximum input voltage is ±10 V (PEAK).
• Upper limit for velocity and displacement
Because velocity and displacement are calculated by using integra-
tion from the acceleration value, the upper measurement limit for
these quantities is determined by the upper measurement limit for
acceleration and the frequency.
