– If a noise level test fails again, make sure the source is working:
– Choose Collect > Experiment Setup > Bench and make sure the Source
option is set to "White Light."
– Choose Collect > Advanced Diagnostics. If the Source icon has a red slash,
replace the source. Otherwise, click the Source icon and check that the
source current and voltage are within specifications.
– If the source is on and the current and voltage are within specifications,
remove any sampling accessory from the spectrometer and put your hand in
the light beam. You should see a spot of yellow light that is about 1 cm in
diameter. If you don't see the light beam,
– If a noise level test fails after you have replaced the source, contact Technical
Support.
• If an X-axis (wavenumber) accuracy test failed:
– Choose Collect > Experiment setup > Diagnostic > Laser Verification, wait for
laser verification to complete and rerun SS.
– If an X-axis accuracy test fails again, visually examine your polystyrene reference
for damage or contamination (the polystyrene reference card for the iD1 or the
polystyrene reference cuvette for the iD1H). If the polystyrene is obviously dirty
or damaged, contact us to buy a replacement reference card or cuvette and then
rerun SS using the new reference card (for the iD1 accessory) or cuvette (for the
iD1H accessory).
– If an X-axis accuracy test fails with a new polystyrene reference card or cuvette,
contact Technical Support.
• If a Y-axis (peak height) accuracy test failed:
– Make sure the C screen from the iS5N accessory kit is installed in the slot
furthest to the right inside the accessory sample compartment.
– If a Y-axis accuracy test fails again, visually examine your polystyrene reference
for damage or contamination (the polystyrene reference card for the iD1 or the
polystyrene reference cuvette for the iD1H). If the polystyrene is obviously dirty
or damaged, contact us to buy a replacement reference card or cuvette and then
rerun SS using the new reference card (for the iD1 accessory) or cuvette (for the
iD1H accessory).
– If a Y-axis accuracy test fails with a new polystyrene reference card or cuvette,
choose Collect > Experiment Setup > Bench and make sure the Gain option is
set to "1" and the interferogram peak maximum is 6 volts or less.
– If the Gain was set incorrectly, reset it and rerun SS.
– If the interferogram peak maximum is greater than 6 volts with the C screen
installed and Gain set to "1", contact Technical Support.
