The status bits have the following meanings:
Temperature Range
This bit is set when the last measurement resulted in a computed
temperature that was outside the measuring range of the
instrument. It is also set when the "crossed wires" condition is
detected.
Execution Error
This bit is set when a valid command has been received and
recognised, but could not be executed at the time for some reason
e.g. sending DATAIogger:STARt when the data logger mode is
turned off. The command is ignored.
Command Error
This bit is set when the command line is not recognised. This could
be an invalid command, parameter or syntax. The command is
ignored.
Measuring
This bit is set when a new measurement starts and is cleared when
complete. It corresponds to the BUSY legend on the front panel
display.
Measurement Available
This bit is set when a new measurement started by the INITiate
command has completed. The bit is cleared when the FETCh?
command is used to transfer the value to the output buffer.
Message Available
This bit is set when the output buffer contains a message. It is
cleared when the buffer is empty.
STATus:QUEStionable:CONDition?

the condition register.
