• If a calibration/validation command is issued during the pause mode or the stop mode in the stream sequence or stream specifi ation
(N times or continuous (set to “0”)) status
(A) The measurement status and the operation mode innediately changes to the requested calibration/validation status and the
run mode, respectively.
(B) The measurement status and the operation mode respectivily return to the stream sequenace status and the stop mode
when calibration/validation is complete for all the spwcifi ed streams.
• If a calibration/validation command is issued during the run mode in the stream sequence status
(1) The measurement status changes to the requested calibration/validation status when the measurement of the currently-
measured stream is completed.
(2) The measurement status and the operation mode respectively return to the stream sequence status and the run mode when
calibration/validation is completed for all the specifi ed streams. The suspended measurement is (not reset but) resumed from
the next stream.
• If a calibration/validation commands is issued during the run mode in the stream specifi cation (N times) status
(3) The measurement status changes to the requested calibration/validation status when the Nth round of the spwcifi ed
measurement is completes.
(4) The measurement status and the operation mode respectively return to the stream specifi cation (N times) status and the stop
mode when calibration/validation is completed for all the specifi ed streams.
• If a calibration/validation command is issued in the stream specifi cation (Continuous (set to “0”))status
(3) The measurement status changes to the requested calibration/validation status when the measurement of the currently-
measured stream is completed.
(4) The measurement status and the operation mode respectively return to the stream specifi cation (Continuous) status and the
run mode when calibration/validation is completed for all the specifi ed streams.

(1) Operation description
For example, this section describes the operation where the stream sequence, calibration, and
validation are set as shown in Table 1.5, 1.6, and 1.7, respectively.
