Use the Average mode to smooth the displayed waveform; multiple data samples will
be averaged. The number of samples to average is selectable from 4, 16, 64, up to
128.
Note:
For best results, the waveform must be repetitive. As the number of average
samples increases the waveform updating time increases. Refer to the following:
1. Press
the
MENU
key; the function menu will appear on the right side of the
screen.
2. Press

or
MENU

to select the
ACQU
(acquisition) mode; Four (4)
selectable options will display at the bottom of the screen.
3. Press
the
F3
key to select
Average Factors
and then press the
F4
key to jump
to
Averages 16
. The meter then averages 16 samples (or acquisitions) and
displays the final result. Refer to Figure 13:

(
SUPERIMPOSING WAVEFORMS
)
Persistence Mode allows the user to hold a displayed waveform on the display while,
at the same time, superimposing the current waveform. The user can select the
amount of time (number of seconds or infinite) to retain the displayed waveform
or set the feature OFF. Refer to the following:
