EEPROM Backup Disk Procedure
Required Equipment and Tools
The correction constants, which are unique to your instrument, are stored in EEPROM on
the A9 controller assembly. By creating an EEPROM backup disk, you will have a copy of
all the correction constant data should you need to replace or repair the A9 assembly.

4. Press . Use the front panel knob
and the softkey (or an external keyboard) to rename the file
“FILE0” TO “N12345” where 12345 represents the last 5 digits of the instrument's

finished renaming the file, press .
5. Write the following information on the disk label:
• analyzer serial number
