SECTION 8 – Maintenance and Service
8.1 ROUTINE MAINTENANCE
Ensure the external surfaces of the unit are clean and free from dust. The sample area should
always be kept clean and any accidental spillage should be wiped away immediately. To give
added protection when not in use, the unit should be disconnected from the mains supply and
covered with the optional dust cover.
The only routine maintenance which maybe required is the replacement of the light source. The
replacement lamp is available from your local distributor or Bibby Scientific (refer to section 7.2 for
spare part codes). Only genuine replacement lamps should be used. Similar lamps may have
different filament configurations or be wavelength restricted for domestic or commercial use and
will give rise to errors if used.
8.2 LAMP REPLACEMENT
8.2.1 Xenon Flash Lamp Module Replacement
Before replacing the lamp disconnect the unit from the mains supply. Access to the xenon flash
lamp module can be gained via removing the top cover of the instrument.
1. Remove the 4 screws located on the underside of the instrument.
2. Lift the top cover clear, taking care not to strain the ribbon cable.
3. Remove the 2 xenon lamp retaining thumb screws.
4. Remove the connector from the rear of the xenon lamp.
5. When replacing the lamp ensure it is pushed fully up into the optics housing before
tightening the thumb screws.

7. Refit and tighten the 4 screws located on the underside of the instrument.
