Calculate2:<Function>:Limit<Y>:Fail - Keithley 2450 Reference Manual

Model 2450 Interactive SourceMeter® Instrument Reference Manual
:CALCulate2:<function>:LIMit<Y>:FAIL?
This command queries the results of a limit test.
Type
Query only
Usage
:CALCulate2:<function>:LIMit<Y>:FAIL?
<function>
<Y>
Details
The results of the limit test for limit Y:
• NONE: Test passed; the measurement is between the upper and lower limits
• HIGH: Test failed; the measurement exceeded the upper limit
• LOW: Test failed; the measurement exceeded the lower limit
• BOTH: Test failed; the measurement exceeded both limits
These commands query the result of a limit test for the selected measurement function.
The response message indicates if the limit test has passed or how it failed.
Reading the results of a limit test does not clear the fail indication of the test. To clear a failure, send the clear
command.
Note that if you are making a series of measurements and auto clear enabled for a limit, the last measurement
limit dictates the fail indication for the limit. If autoclear is disabled, you can take a series of readings and read
fails to see if any of one of the readings failed.
To use this attribute, you must set the limit state to enable.
Example
CALC2:VOLT:LIM1:LOW 0.25
CALC2:VOLT:LIM1:UPP 2.5
CALC2:VOLT:LIMIT1:STAT ON
CALC2:VOLT:LIMIT1:FAIL?
