Condition Errors 65 to 92, Calibration Needed (Extended)
This series of errors corresponds to the bits in the 
STATus:QUEStionable:CALibration:EXTended:NEEDed sub-register. 
The second column in the table below shows the corresponding bit in that 
register.
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 72 indicates that the “Input Attenuation not calibrated” 
condition has been detected, and error 1072 indicates that failure has been 
cleared.
This register is summarized as bit 8 of the 
STATus:QUEStionable:CALibration register, as described in the section 
“Condition Errors 36 to 64, Calibration Needed or Failed” on page 116.
