Example
: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.
