STEP 6. Back Up the EEPROM Disk

STEP 6. Back Up the EEPROM Disk

Description

Correction constants are stored in EEPROM on the A7 controller assembly. The advantage of having an EEPROM backup disk is the ability to store all the correction-constant data to a new or repaired A7 assembly without having to rerun the correction-constant procedures. The analyzer is shipped from the factory with an EEPROM backup disk which is unique to each instrument. It is prudent to make a copy of the EEPROM backup disk so that it can be used in case of failure or damage to the original backup disk.

Equipment

3.5-inch disk 92192A (box of 10)

CAUTION Do not mistake the line switch for the disk eject button. If the line switch is mistakenly pushed, the instrument will be turned off, losing all settings and data that have not been saved.
