General Instructions:
1. Three lamps should be scanned bi-weekly. If all three lamps give approximately the same
results, then the test is complete. If one lamp gives results that are different from the other
two, then a fourth lamp should be chosen and the scan run yet another time. The lamp giving
the ‘odd’ reading should be noted and not used again.
2. Once every two months, all five lamps should be scanned to make sure they all give the
same results so availability of spares is assured.
3. In the event that the % difference for all lamps is much greater than 5%, it may be necessary
to perform other scans which will be used to create new response files for the instrument.
See Appendix C.
4. Perform the TU test prior to changing the response file to make sure that the Zenith Prism is
properly aligned. See section 4.
6. UV STABILITY CHECK - QL
