:CALC2:VOLT:LIM1:CLE:AUTO OFF
:CALC2:VOLT:LIM1:AUD FAIL
:CALC2:VOLT:LIM1:LOW 0.25
:CALC2:VOLT:LIM1:UPP 2.5
:CALC2:VOLT:LIMIT1:STAT ON
:READ?
:CALC2:VOLT:LIMIT1:FAIL?
:CALC2:VOLT:LIM1:CLE
Set limit autoclear off.
Enable the beeper for limit 1 when a voltage measurement
exceeds the limit.
Set lower limit 1 for voltage to 0.25 V.
Set upper limit 1 for voltage to 2.5 V.
Enable limit 1 testing for voltage.
Make a reading; the limit is checked and results display on the
front panel.
Return the test results; example output if the test fails on the
low limit:
LOW
Clear the test results.

Details
This command queries the result of a limit test for the selected measurement function.
The response message indicates if the limit test passed or how it failed (on the high or low limit).
If autoclear is set to off, reading the results of a limit test does not clear the fail indication of the test.
To clear a failure, send the clear command. To automatically clear the results, set auto clear on.
If auto clear is set to on and you are making a series of measurements, the last measurement limit
determines the fail indication for the limit. If auto clear is turned off, the results return a test fail if any
of one of the readings failed.
To use this attribute, you must set the limit state to on.
