Condition Errors 601 to 699, Error Summaries
This series of errors corresponds to the bits in the
STATus:QUEStionable
register, read with a
STATus:QUEStionable?
event query or a
STATus:QUEStionable:CONDition?
query.
The second column in the table shows the corresponding bit in the status
register. These bits do not have any corresponding error messages, although
error numbers have been reserved for them as seen in the Err# column; they
are status bits only.
The bits in the
STATus:QUEStionable
register are “summary bits” for
registers at a lower level. Note that these summary bits summarize the state
and history of the event registers at the lower level. This is true even for bits in
the
STATus:QUEStionable
condition register. This means that:
— The summary bits read by the
STATus:QUEStionable: CONDition?
query are true if any event bits are set in any of the :QUEStionable
sub-registers :POWer, :TEMPerature, FREQuency, CALibration or :INTegrity.
— The summary bits read by the
STATus:QUEStionable?
event query are
true if any event bit has undergone a false-to-true transition with the
PTRansition filter set, or a true-to-false transition with the NTRansition filter
set, in any of the :QUEStionable sub-registers :POWer, :TEMPerature,
FREQuency, CALibration or :INTegrity.
Thus, the summary bits cannot be used to determine the current state of a
lower level condition bit; only the state and history of the lower level event bits.
