The actual sweep time is shown on the FieldFox screen. See the Screen Tour
on
“Screen Tour” on page 44. To increase the sweep time, enter a value that is
higher than the actual sweep time. The increase will not be exactly the amount
that you enter, as the actual sweep time is the composite of many factors.
