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.

•Analysis type - Back-erasing is unavailable for filtered studies.

•Viewing areas - You must be in either the View Current Studies or View Session viewing area. Back-erasing is not available in View Past Studies.

•Restricted to the pause -You can back-erase only during the pause that follows a study. Back-erasing is not available for past studies in the session.

•Not all studies - Because back-erasing requires a manual intervention, it is unavailable for triggered or Auto-Run studies.
