Disassembly and Replacement
3. Remove the two screws at the front of the circuit board securing the
circuit board to the base assembly.
The screws securing the circuit board also secure the monochromator
cover.
4. Carefully lift the circuit board off the base assembly.
REPLACEMENT
5. The EEPROM contains the calibration constants for the monochromator
and other instrument parameters. This information is specific to a
specific instrument and must be maintained with the instrument. If the
circuit board is being replaced with a new board, the EEPROM must be
transferred to the new circuit board.
