5.4 Accelerometer view
5.4.1 Output data values
Shown below is the output data view for accelerometer sensors. The GUI can show output data
values on charts, as well as on numeric indicators. The output data values (possibly averaged by
the
moving average
filter; see 5.3.9) are added to chart traces (each trace is a line on the chart).
The numerical values
Average
,
Minimum
and
Maximum
are calculated for the data points currently
shown on the chart. In addition to the output values for each axis, the numeric values include
standard deviation (if enabled in
Setup
view) and possibly a resultant value. The resultant is
calculated according to the following formula:
Resultant =
2

z
y
x
The output data view also shows indicators for the data rate, sensor temperature and sensor
status. The amount of data points on the chart can be changed using the
Data points
control and
the range of the chart using the
Chart range
control. Note that the amount of data points affects
only the number of output data values on the chart and not the averaged output value.
Figure 17. Output data view for accelerometer sensors
Note: The sensor axis count and axis directions are determined by the selected sensor type,
and output data values are shown only for these axes. If the sensor type was auto detected
and the wrong axis information is shown, check the About view to see if the sensor type
was correctly detected.
