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 Tungsten Halogen Lamp Replacement
Before replacing the lamp disconnect the unit from the mains supply and ensure the lamp is cool
before handling. Care should be taken when removing the lamp from the holder. Access to the
tungsten halogen lamp can be gained via the lamp access panel located on the rear of the
instrument (refer to section 2.5).
1. Slacken off the thumbscrew from the lamp access panel located at the rear of the unit.
2. Remove the old lamp from the holder. The lamp is a plug-in fit and should be removed by
gently easing it from the holder.
3. Carefully remove the replacement lamp from the packaging. Ensure that the glass portion
of the lamp is not touched as finger marks will damage the lamp resulting in a reduced
performance. If accidental damage occurs the surface of the lamp may be cleaned using
propan-2-ol.
4. Insert the lamp into the holder, ensuring it is fully pushed in.
5. Replace the lamp access panel and re-tighten the thumbscrew.
6. Reconnect the power supply, turn on the unit and ensure that the lamp is illuminated after
a few seconds.
