Saving changes into Non-Volatile RAM
After changes have been made by manual calibration or on any of the
page screens, the system LED will turn red. This indicates that there is a
system error or system state change.
The analyzer must be in Idle or Warmup Mode in order to accept or save
changes into Non-Volatile RAM.
Use the Page key to move to the System Settings page. Any changes
made will be shown under the System Errors line. Use the arrow keys to
move the cursor in front of the change you wish to accept and press the
key under the Accept menu label. Next, press the Save key to save the ac-
cepted changes into Non-Volatile RAM.
NOTE: Any changes made will be lost if the instrument is turned off
before the changes have been accepted and saved on the System Set-
tings page.
Run
From the Run Screen press Run and automatic operation of the analyzer
will begin. The analyzer will display the time left, in seconds, for the cur-
rent cycle in the status window. The results will be updated in the screen
as the concentration is determined.
Run Mode Screens
To stop the instrument press the Idle key and an asterisk will appear next
to “Run Mode” in the status window. This asterisk indicates that the
instrument will stop running at the end of the next cycle. To continue
running the instrument after the Idle key has been pressed, simply press
the Idle key again and the Pound will disappear and the instrument will
continue to automatically run samples.
