Setting Description
Zero Reference
When the Math State is set to On, this setting specifies the
reference used when the math operation is set to percent; the
range is -1e12 to +1e12.
Limit 1 and Limit 2
These settings enable or disable limit testing. The Limit options
allow you to do pass-or-fail limit testing using the front panel of the
instrument. When you do a limit test, the Home screen displays the
pass or fail result of the test.
Limit State enables or disables a limit test for the selected
measurement function. When testing is enabled, limit testing
occurs on each measurement. Limit testing compares the
measurements to the high and low limit values. If a measurement
is outside these limits, the test fails. If a measurement is in the
limits, it passes.
Config
Displays the settings that are available for the limit functions.
Auto Clear
Auto clear indicates if the high and low limits should be cleared
automatically or not.
Low Value
The Low Value specifies the lower limit for limit tests.
High Value
The Limit High Level specifies the upper limit for a limit test.
Audible
Audible determines if the instrument beeper sounds when a limit
test passes or fails, or disables the beeper.
