The HVM100 measures the following quantities:
Running RMS
Acceleration
LINEAR
Integration time, in seconds.
t
o
= Observation time
The linear Arms integration time is controlled by the Averaging time setting;
a new linear Arms value is calculated and displayed at the end of each inte-
gration period.
Running RMS
Acceleration
EXPONENTIAL
Time constant of the measurement.
An averaging time of SLOW is equivalent to a time constant of 1 second.
