● In the case where a stream sequence change command is received during the run mode in
the stream specifi cation status (for continuous measurement) [2A2]
The measurement status is changed to the requested stream sequence status when the
measurement of the currently-measured stream is completed.
In this case, the operation mode remains unchanged from the run mode.

● In the case where a stream sequence change command is received during the run mode in
the stream specifi cation status (for N times of measurement) [3A2]
The measurement status is changed to the requested stream sequence status when the
Nth round of the measurement of the currently-measured stream is completed.
In this case, the operation mode remains unchanged from the run mode.

Run command
● In the case where a stream sequence change command is received during the pause mode
in the stream specifi cation status [2A6]
The measurement status is immediately changed to the requested stream sequence status.
In this case, the operation mode changes to the stop mode and valves are all closed (turned
off).

● In the case where a stream sequence change command is received during the stop mode in
the stream specifi cation status [2A1]
The measurement status is immediately changed to the requested stream sequence status.
In this case, the operation mode remains unchanged from the stop mode.
