● In the case where a stream specifi cation change command (for N times of measurement)
is received during the run mode in the stream specifi cation status (for N times of
measurement) [3C2]
The measurement status is changed to the requested stream specifi cation status (for N
times of measurement) when the Nth round of 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.

Run command
● In the case where a stream specifi cation change command is received during the stop
mode in the stream specifi cation status [2B1]
The measurement status is immediately changed to the requested stream specifi cation
status.
In this case, the operation mode remains unchanged from the stop mode.

Stop
● In the case where a stream specifi cation change command is received during the pause
mode in the stream specifi cation status [2B6]
The measurement status is immediately changed to the requested stream specifi cation
status.
In this case, the operation mode changes to the stop mode and valves are all closed (turned
off).

Stop
● In the case where a stop command is received during the run mode in the stream
specifi cation status (for continuous measurement) [2E2]
The operation mode is immediately prepared to be changed to the stop mode.
The operation mode changes to the stop mode in the stream specifi cation status (for
continuous measurement) when the measurement of the currently-measured stream is
completed.
The stop command can be canceled with a cancel command until the operation mode
changes to the stop mode.
