Detector accessory is supported by
Spectrum version 6.3.5 (or later) for the Spectrum 400 Series Spectrometers, or Spectrum
version 6.3.3 (or later), or Spectrum Express version 1.2 (or later), for the Spectrum 100 Series
Spectrometers.
This section describes how to create a modified instrument configuration file for use with an
external detector.
NOTE: It is not necessary to power the instrument to complete this procedure.
1.
Browse to C:\pel_apps\bin\
The instrument configuration file is named C*****.cfg, where ***** is the five-digit serial
number of the instrument.
The spectrometer serial number is located on its base casting, in the sample compartment,
under the sample accessory baseplate.
2.
Copy the appropriate C*****.cfg file and save it as, for example, C*****.intdet
NOTE: Make sure you save this backup of the original instrument configuration file. If you
remove the optical bench, you will re-instate this file.
