5.2.1 Principal display
An example of this display is given above. It shows the details of the current sample being
measured. In this example, the measurement is for Channel 1 (channel name of Sample 1), but
this will change as the analyzer switches to the next measurement channel in the user-defined
sequence.
The options at the bottom of the screen will include three of the following:
• Hist - Selecting this option will show the last measurements for each channel (see Figure 17
on page 64 as an example) along with the last grab sample and verification details.
• Stop - Select this option to stop the current process on the analyzer. This could be a
measurement, verification or grab sample process. The option is only available when one of
these processes is currently running. You will be asked for confirmation (YES or NO) that you
want to stop the process.
• Start - Select this option to start the analyzer measurement process. This option is only
available if the analyzer has been stopped.
• Menu - This will bring up the main menu screen as illustrated in Figure 19 on page 66 .
• Alarm - This option will appear flashing on the screen if any alarms have been set. Selecting
this option will take you to the alarms screen as illustrated in Figure 18 on page 65 .
