The sampling accessory can be accessed through the sample
chamber lid.
Top/Bottom Case Assemblies
– The top and bottom case
assemblies can easily be separated by unscrewing the four recessed
screws in each corner of the base. This should be done without
inverting the unit, by moving it forward over the front edge of the
bench to unscrew the front two screws, and then turning it around
to do the same with the back two. Turn it back round and then the
top half of the case can be lifted off the bottom half take care not to
strain any cables between the top and bottom sections.
Should it be necessary to work on the top case assembly by itself it
is simply a matter of disconnecting the plug from SK5 on the
power supply PCB then the top can be completely removed.
Microprocessor/Display PCB
The microprocessor/display PCB is
mounted in the top case assembly. To remove it disconnect SK1 on
the ribbon cable to SK5 and PL106 to the membrane keypad.
Unscrew the four screws and the PCB can be removed. The display
module and microprocessor PCB should be treated as a pair and
replaced together. Removing the display from the PCB should not
be attempted.
Detector PCB
The detector PCB is mounted vertically at the far
right hand side of the lower chassis. It is easily removed by
unscrewing the two screws recessed in the top of the metal
mounting block. SK4 on the power supply PCB should be removed
and the ribbon cable pulled back under the monochromator (it may
be necessary to lift the monochromator to complete this task).
Remove the two screws and spacers that hold the lens block, take
care not to rotate it as the detector is mounted in a recess inside the
block and can easily be broken off. Remove the last screw with its
nut and washer to enable the electrostatic screen to be removed
from the PCB.
The Detector PCB stores detailed calibration data relating to the
optics of the unit it is fitted in, replacing the detector PCB without
a full re-calibration will invalidate the quoted specification.
Monochromator
The monochromator is located across the front of
the lower case. It is a sealed unit and breaking the seals will
