The following explain each operation mode in detail.
(1) Stop
In the Stop mode the measurement stops. When power is applied, the operation mode
enters Stop. Settings should be changed in this Stop mode.
CAUTION
If settings are changed in an operation mode other than the Stop mode, the analyzer may
not accept the change and run under the previous setting.
When the operation mode is transferred to the Stop mode from others, the on-off statuses
of various valves and stream valves remains unchanged.
(2) Run
In the Run mode, the measurement runs. If the Auto Start Set is set to Enabled, the
GC1000 Mark II automatically enters the Run mode after the time set for the "Auto start
time" elapses after power is applied. When the operation mode is transferred from the
Stop mode to the Run mode, the measurement starts after the Warming up time for dis-
placement in the sample stream elapses. For the Warming up time, see Section 4.3,
“Method”. If a level 1 alarm occurs during the Run mode, the mode changes to the Stop
mode after an ongoing measurement of the stream has been completed.
(3) Pause
In the Pause mode, the measurement pauses at the specified Pause Time. For the Pause
Time, see Section 4.3, “Method.”
When the operation mode is transferred from the Pause mode to the Run mode, the
measurement resumes at the Pause Time.
When the operation mode is transferred from the Stop mode to the Pause mode, the on-off
statuses of various valves including stream valves become those at the Pause Time of the
stream to be measured next.
