Home Page - Quick Train
The Home Page offers a route to quickly training the Lonestar for any sample under investigation. Note that this function does not offer as detailed or precise training as in the Process Review Application, however it can be used for quicker setup when multiple tests are being performed, or for allowing minor adjustments to the Process Monitoring.
Quick Train steps:
- Run the Lonestar as normal at your required flow rate and field intensity.
- Allow the system to stabilise whilst sampling a known ‘good’ sample.
- Once the system is stable click the ‘Train’ button – It will change to ‘Training’.
- The System Information graph will also change to ‘Ion Current Deviation’ automatically.
- The Lonestar will continue to collect data from the ‘good’ sample and it will calculate estimated threshold levels for the alarms based on the variation seen in this data. (Note that the more data that is collected the more reliable the alarm thresholds will be).
- Once sufficient data has been collected unclick the ‘Training’ button.
- Click the Monitor button - It will change to ‘Monitoring’ and will lock out certain functions on the software to prevent accidental changes to the Process whilst monitoring is occurring.
- The system will now monitor both positive and negative mode ions looking for any deviation from what the system has been taught to be normal. If any alarm occurs it will show in the Master Alarm on the navigation bar as well as appearing in the Alarm History.
Note that you can manually adjust the threshold levels after the Training has been stopped, but before Monitoring has been started. You may wish to set higher or lower thresholds depending on your knowledge of the system or process.
In the System Settings screen (see next chapter) you can program the Lonestar to trigger a full DF Matrix sweep when an alarm status changes or at regular time intervals. During these DF Matrix sweeps the Process Monitoring will switch off and the Alarm Status bar will turn black. This feature allows a more detailed analysis of the process line to be obtained at regular intervals or whenever an alarm is triggered.
For more details on System Training see the section on Training the System in the Process Review Screen. This gives a breakdown of exactly how the Lonestar is calculating the Alarm Level.
