QUEStionable:INSTrument:ISUMmary{1|2|3} subregister
This is the subregister of bit 1 to bit 3 of the QUEStionable:INSTrument subregister. This is a 16-bit register that stores information related to the status of and the questionable events that occur during operation of the PCR-LE/PCR-LE2 Series.
Of the parameters {1|2|3}, 1 represents U phase, 2 represents V phase, and 3 represents W phase.
For example, V phase is specified as "QUES:INST:ISUM2".
The QUEStionable status register bits may indicate that there are problems with the PCR-LE/PCR-LE2's measured data.
