NOTE:
If your Spotlight 200 system is supplied with a Frontier or Spectrum 400
FT-IR/FT-NIR dual-range spectrometer and you are using a large aperture in the
near infrared, the software may report an overload error when monitoring an IR
function or collecting data. To resolve this, fit a 32%T attenuator to the external
beam window of the spectrometer. See
, on page 48, for details.
This attenuator should be kept in place during data acquisition.

Fitting an Attenuator to the Spectrometer
If your Spotlight 200 system is supplied with a Frontier or Spectrum 400 FT-IR/FT-NIR
dual-range spectrometer, you will be provided with an Attenuator kit (part number
L1160560) containing 1%T, 4%T, 6%T, 14%T and 32%T attenuators. The attenuators
attach to the external beam window of the spectrometer magnetically.
When examining samples in the visible range on systems fitted with an MCT detector, use of
the 1%T attenuator is recommended if the image appears with a red tint. However, the
attenuator should be removed during data acquisition.
Use of the 32%T attenuator is recommended if an overload error message is displayed when
using a large aperture. This attenuator should be kept in place during data acquisition.
