Condition Messages
An event with the error number shown in the table means the condition has 
been detected. When the condition is cleared, an event with the error number 
plus 1000 is generated. These error numbers can be viewed in the Show Errors 
screen, along with the DETECTED and CLEARED indicators.
For example, error 301 indicates a Meas Uncal condition has been detected, 
error 1301 indicates that failure has been cleared.
This register is summarized as bit 3 of the 
STATus:QUEStionable:INTegrity register, as described in the section
