Supplementary Explanation
(a) The above real-time communication indicates a communication carried out while the
instrument is engaged in analysis, and the batch communication indicates a
communication when specified through the screen.
(Note, however, that test selecting information inquiry is not specifiable through the
screen but specifiable only from the host.)
(b) To stop communication between the analyzer and host, change [RUN] (highlighted)
to [CANCEL] for host communication on the start condition screen. In this case,
however, remember that the entire communication processing will be suspended.
(c) Stat sample test selecting information is specifiable from the host, in response to
inquiry from the analyzer during real-time communication. However, an
independent specification from the host is invalid.
