● In the case where a stream sequence change command is received during the run mode in
the stream sequence status [1A2]
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.
* Requests for changes to the same stream sequence number are invalid.
● In the case where a stream sequence change command is received during the pause mode
in the stream sequence status [1A6]
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).
* Requests for changes to the same stream sequence number are invalid.

● In the case where a stream specifi cation change command (for continuous measurement)
is received during the run mode in the stream sequence status [1B2]
The measurement status is changed to the requested stream specifi cation status (for
continuous measurement) 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 specifi cation change command (for N times of measurement) is
received during the run mode in the stream sequence status [1C2]
The measurement status is changed to the requested stream specifi cation status (for
N times of measurement) when the measurement of the currently-measured stream is
completed.
In this case, the operation mode changes from the run mode to the stop mode when the Nth
round of the specifi ed measurement is completed.
