Operation Modes
DC OUT signal
The DC signal supplied at the DC OUT connector on the rear panel is obtained
by rms conversion of the AC signal with a time constant of 1 second.
Range full-scale value: 1 V
The measurement value can be calculated from the selected range and
the voltage, according to the diagram below.
Example: Range 100, measurement mode m/s 2
Overload indicator LED
At each range setting, measurement is possible up to a point about ten
times (+20 dB)* higher than the range full-scale point.
* Dependent on display characteristics
For example, if the range setting is 10 m/s 2 , measurement is possible up
to about 100 m/s 2 without saturation.
Because velocity and displacement are calculated by integration from the
acceleration value, the upper measurement limit for these quantities is deter-
mined by the upper measurement limit for acceleration and the frequency.
When saturation of the internal circuits occurs, the red overload indicator
LED lights up. In this case, correct measurement is not possible.
