Limits Testing Example 2—Flag On Limits but
Continue Measuring
If you decide that you want the Counter to flag measurements that are out
of limits but to continue taking measurements, then perform the following
steps.
1 Press Limit Modes key until
ON FAIL: STOP
is displayed.
2 Press any one of the arrow keys to toggle to the next state.
ON FAIL: GO ON
is displayed.
3 Press Run key to start making measurements with this limits-testing
choice selected.
Now, each time a measurement drifts out of the user-entered limits the
Limit annunciator in the display will light, but the Counter will continue
to make measurements.
The Limit annunciator will go on whenever a result is out of limits.
As soon as a result is within limits, the Limit annunciator will go off.
