Plot averaging allows random road noise or
background levels to be averaged for a smoother
plot on display. This does not affect logged data.
Most users may find an averaging factor of 4 to
be optimal for most roads.
Users can set the name of the log file, such as
adding a date or location for easy recall of the
computer. If a new name is not assigned each day,
for instance, the standard file is appended with
corresponding date, time and levels.
Logged Data
When data is logged, it is logged as a Comma Separated Value (.csv) and can
be displayed in Microsoft Excel as the following picture.
The first column denotes that time and date, and also the markers (if added),
Column B gives the axis (X, Y, Z or I for Isotropic), Column C indicates BP for
Bandpass or HH for Harmonic mode, Column D indicates highest signal
