About the Questionable Data Register
The questionable data register reports the quality of the DMM’s
measurement results, as well overload conditions and high/low limit test
results. Through the enable register, all of the conditions can be reported
in the questionable data summary bit. At the moment, you have to write
a decimal value by using the STATus:QUESTionable:ENABle command to
set the enable register mask.
