Bit B11, Buffer Pretriggered (BPT)
Set bit indicates that the trace buffer pretrigger event
has occurred (PTR), or the operations associated with the pretrigger have been completed
(NTR).
Bits B12 through B15
Not used.
Questionable Event Register:
Bits B0 through B3
Not used.
Bit B4, Temperature Summary (Temp)
Set bit indicates that an invalid reference junction
measurement has occurred for thermocouple temperature measurements (PTR), or a subsequent
valid reference junction measurement has occurred (NTR).
Bits B5, B6 and B7
Not used.
Bit B8, Calibration Summary (Cal)
Set bit indicates that an invalid calibration constant was
detected during the power-up sequence (PTR). The instrument will instead use a default calibra-
tion constant. This error will clear after successful calibration of the instrument.
Bits B9 through B13
Not used.
Bit B14, Command Warning (Warn)
Set bit indicates that a Signal Oriented Measurement
Command parameter has been ignored (PTR), or a subsequent Signal Oriented Measurement
Command has executed successfully (NTR).
Note: Whenever a questionable event occurs, the ERR annunciator will turn on. The annunciator
will turn off when the questionable event clears.
