3 CALCulate Subsystem
102 U8480 Series Programming Guide
CALCulate[1]:LIMit:FCOunt?
This query returns the total number of limit failures. 
If the appropriate STATe commands are set to ON, each time a measurement is 
initiated and the result is outside the limits, the counter is incremented by one.
If the measured value is equal to a limit, this is a limit pass.
The counter is reset to zero by any of the following commands:
–*RST
– CALCulate[1]:LIMit:CLEar[:IMMediate]
– CALCulate[1]:LIMit:CLEar:AUTO ON
When CALCulate[1]:LIMit:CLEar:AUTO is set to ON, the counter is set to zero 
each time a measurement is:
–measured using MEASure?
–read using READ?
– initiated using: 
– INITiate[1][:IMMediate], or
– INITiate[1]:CONTinuous ON
When CALCulate[1]:LIMit:CLEar:AUTO is set to ONCE, the counter is set to zero 
the first time a measurement is:
–measured using MEASure?
–read using READ?
– initiated using: 
– INITiate[1][:IMMediate], or
– INITiate[1]:CONTinuous ON
The maximum number of errors is 65535. If more than 65535 errors are detected, 
the counter returns to zero.
