Fail When

Fail When
The Fail when softkey brings up a second level softkey menu on the display.
Fail when allows you to select when the oscilloscope decides that a test has
failed, and what to do with invalid measurements.
The four choices are fail inside the limits, outside the limits, always fail, or
never fail.
Fail
Inside Fail inside causes the oscilloscope to fail on a test when the
measurement results are within the parameters set by the Lower limit
and Upper limit softkeys.
Outside Fail outside causes the oscilloscope to fail on a test when the
measurement results is greater than the upper limit or is less than the
lower limit.
Always Fail always causes the oscilloscope to fail on a test every time
the measurement is executed, and the parameters set by the Lower limit
and Upper limit softkeys are ignored. Use the fail always mode when you
want to log the action each time the measurement is executed.
Fail always allows you to monitor trends in measurements. For example, you
may want to track a measurement during an environmental test while the
oscilloscope is running a measurement for a long time as the temperature or
humidity is changed. Each time the measurement is executed, the results
are logged as determined by the Fail action softkey.
