Setting up General Acquisition Parameters
The general acquisition parameters influence how the acquisition occurs.
³
You can select whether the unit beeps after each measurement or not.
³
You can set the acquisition to be continuous, or requiring that you start
each measurement manually.
³
You can set the default spatial smoothing filter, in meters. The spatial
smoothing filter helps improving the measurement results in filtering
the cumulative PMD curve. The default value is 4000 m. Increase this
value if the PMD cumulative curve is appropriate, but wavy, for
example. Decrease this value if you are interested in seeing where the
PMD begins to increase. You can find more information on the spatial
smoothing filter in Use an Appropriate Spatial Smoothing Filter Value
on page 129.
