Limits Testing Example 4—Selecting Filtering Conditions of 
Stats Computation
Let’s assume you have set the upper and lower limits to reasonable values 
as in the previous procedure.
NOTE
Since the Limit Testing and Stats functions are independent, 
LIM TEST:
 
doesn’t have to be ON in order to filter measurements for statistics.

USE: ALL  MEAS
 is displayed.
2 Press any one of the arrow keys to display 
USE: IN  LIMIT
.
3 Press Run key to start the measurement.
The Counter will compute statistics using only measurements that are 
within the user-entered limits.
4 Press Stats key until 
USE: IN  LIMIT
 is displayed.
5 Press any one of the arrow keys to display 
USE: ALL MEAS
.
The Counter will compute statistics using all measurements, whether 
they fall in or out of the user-entered limits.

7 To turn off the Limit Testing, perform the following steps:
a. Press Limit Modes key until

When Limit Testing is off, the Limit annunciator, the stop-on limit 
capability, the limit graph, and the rear panel RS-232 Limit Output 
(if DTR: LIMIT choice was selected as described in the following 
Example 5 procedure) are disabled.
NOTE
Stats will still filter data using your upper and lower limits if you set Stats 
to USE: IN LIMIT.

measurements.
