Figure 4.31 Example of GCM General Information Display Area
 Method number indicator
Indicates the method number (1 to 6).
The indication is blank when the GCM is in manual or process - stop state.
 Stream valve indicator
Indicates the stream valve status, either in terms of stream valve number or OFF.
 Atmospheric balanced valve indicator
Indicates the status (ON or OFF) of the atmospheric pressure balancing valve. This indication is
hidden if an atmospheric pressure balancing valve not available.
(B) Elapsed time bar indicator
This area indicates the elapsed time of GSM and its subordinate SYS, as well as the ON/OFF
timings of stream valve and atmospheric pressure balancing valve.

Figure 4.32 Display Example of Elapsed Time Bar
The GCM elapsed time is indicated in terms of the elapsed time (in seconds) since the beginning
of analysis, and the ratio (percentage) of elapsed time to the analysis interval.
When the GCM is in manual mode, the time axis is automatically adjusted, so that the elapsed
time is indicated in terms of the ratio (percentage) to the full scale.
