Measurement mode with averaging of signal
In some cases, during testing materials with high damping, when
controlling of large tested objects and operating at high scanning
duration, noise amplitude can be compared with the amplitude of the
useful signal and on the background of strong noise useful signal is
difficult to detect.
For these cases, in the device is implemented the averaging mode,
which can be done by 2, 4, 8 and 16 signals. To activate the
averaging in the group of parameters "Functions" select and activate
the parameter "AVG." and set required number of averaging.
Caution, when the averaging mode activated it is reduced frequency
of refreshing of signal on the display.

Measurement mode with signal accumulation
In some cases it may be necessary to detect the maximum of signal,
and get an envelope of signal during scanning.
To activate the envelope mode in group settings "Functions" select
the "PEAK" and set the required parameter - on or off.
