Example Procedure for Filtering Data (Using Limits) During Stats
1 Using the procedure in the previous sub-section titled “Example Procedure for
Computing Stats,” set up the Counter to display the minimum frequency value
of an input signal.
2 Set the upper and lower limits. (Refer to the section in Chapter 1 titled “To Set
Limits of Measurements” if needed.)
3 Press Stats key until USE: is displayed.
4 Press one of the arrow keys to toggle to IN LIMIT state.
USE: IN LIMIT is displayed.
5 Press Run key.
The Counter will now perform the statistical computations (that is, standard
deviation, mean, maximum, and minimum) on only those measurements that are
within the user-entered limits. The Counter then displays the statistics you picked
(minimum, in this case).
6 Press Stats key until USE: is displayed.
7 Press any one of the arrow keys to toggle to ALL MEAS state.
USE: ALL MEAS is displayed.
8 Press Run key.
The Counter will now perform the statistical computations (that is, standard
deviation, mean, maximum, and minimum) on all measurements, whether they fall in
or out of the user-entered limits. The Counter then displays the statistic you picked
(minimum, in this case).
