Time History/Back-erase screen
When conducting a broadband study, you can view as much as the last 20
seconds of Max SPL in this screen. The current Max appears at the right
border of the Time Log chart (time=0) and advances, in one-second
increments, toward the left border of the chart. The data leaving the chart at
the left border is always a measurement that occurred 20 seconds ago.

Back-erasing

You can remove undesirable data at the end of a study with a process called
back-erasing. Back-erasing is available only under these conditions.
