(3) Operation in the stream specifi cation status
• In the stream specifi cation status, a specifi ed stream is measured continuously (when the
preset number is 0) or a preset number of times (when the preset number is 1 to 9999). To
specify a stream, touch the “Stream specifi cation” button to open the specifi cation window
on the GCM operation status screen on the analyzer operation display (Figure 5.5).
Users at Level B or higher are allowed to specify a stream and change the measurement
status.
• In the stream specifi cation status, operation stops after the preset number of times of
measurement.
• When a command is issued to change the measurement status to the stream specifi cation
status during the pause mode in the stream sequence status or the stream specifi cation
status, the measurement status is changed to the requested status but the operation mode
changes to the stop mode and valves are all turned off. Then change the operation mode (to
the run mode or pause mode).
• If a command is issued to change the measurement status to a stream specifi cation status
of which GCM numbers or Method numbers have been inappropriately defi ned on the
“Stream specifi cation” screen on the EtherLCD, an “ALM#454: Failed to change operation
mode, Level 3” alarm is activated and the operation mode is not changed. (When the
operation mode changes from the stop mode to the pause mode or run mode, an alarm is
immediately activated. In case where a command is issued to change the measurement
status to an inappropriately defi ned stream specifi cation status during the run mode in the
stream sequence status or the stream specifi cation status, an alarm is activated when the
measurement of the currently-measured stream is completed and preparation starts for the
measurement of the specifi ed stream.)
