CELL PROGRAMMER - REMOVAL AND REFIT
This procedure is essential for the fitting of any of the alternative cell holders
available for long pathlength cells, single cell thermostatting, or the MiniSipper.
If the Cell Programmer basket is removed / replaced at any time, the 'Refit'
procedure must always be repeated.
REMOVAL:
Holding the basket firmly with one hand, unscrew the central screw anti-
clockwise until the basket is released.
REPLACE THE COVER ON THE OPTOSENSOR, and secure the cell holder.
REFIT:
Remove the cover from the optosensor, and remove the cell holder.
Indentify the position of the 'keyway' on the motor shaft.
View the underside of the basket to locate the position of the moulded 'key'.
Re-locate the basket on the shaft ensuring a positive location of the key in the
keyway, and tightened the central screw clockwise.
From the CELL PROG page use the INITIALISE function key to correctly
align the basket with the spectrophotometer.
This last action is important to ensure the correct operation of the system. Whilst
there is significant resistance to manual movement of the motor, it is suggested
that 'as routine' initialisation of the Cell Programmer should be performed as a
check before any measurements are performed.
