(3) Auto-operation starting function
Auto-operation starting function operates the analyzer at process status Run mode without
manual operation. When the auto-operation is started, consecutive measurement of the streams,
which were set to the stream sequence 1, is performed in order.
It is required to supply power, protection gas, carrier gas, and utility gas sample to the analyzer in
the same manner as when starting up the device manually.
