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:
1. Press the MENU key; the function menu will appear on the right side of the
screen.
Press MENU ▲ or MENU ▼ to select DISP SET. Four (4) selectable options
2.
will appear at the bottom of the screen.
3. Press the F2 key to select 1 sec, 2 sec, 5 sec, infinite or OFF. Select a 1, 2,
or 5 second waveform display duration as desired. When Infinite is selected
the waveform will remain on the screen indefinitely. When OFF is selected,
the Persistence function has no effect on displayed waveforms.
