Instrument performance testing
Problem
The results of your instrument performance tests do not meet
specifications (the results obtained during factory testing are
included in the packing crate with the instrument).
Solution
Check the following:
❑
The sample compartment is empty.
❑
The cable connecting the instrument to the PC is correctly
connected and the retaining screws are tightened.
❑
The lamp is pulsing during initialization. This is indicated if the
green power indicator on the front of the instrument flashes
(you should also hear the monchromator and the filter wheel
moving). You should also turn the instrument on its side and
look through the small lamp viewing hole in the base of the
instrument. If the lamp is not pulsing you may have a hardware
conflict (see sections 4.3/4.4).
❑
The lamp is correctly aligned (refer to Chapter 3 for
instructions on aligning the lamp).
Warning
When operating, the lamp module emits high intensity light
which can damage eyes. To avoid eye damage, never operate
the lamp module outside the instrument.
The lamp module contains components operating at high
voltages. To avoid electric shock, NEVER disassemble the
lamp module.
