Persist
When the Persist function is used, the persistence display effect of the picture tube
oscilloscope can be simulated: the reserved original data is displayed in fade color and
the new data is in bright color. With the F2 menu selection button, different
persistence time can be chosen: 1sec, 2sec, 5sec, Infinite and Closed. When the
"Infinite" option is set for Persist time, the measuring points will be stored till the
controlling value is changed (see Fig.50).
