2. Convert the IDRaman mini to a Mass Storage Device (MSD) by clicking on USB connection
button in the Tools menu on the IDRaman mini.
--OR--
Open TeraTerm and type reset msd. This converts the IDRaman mini to a Mass Storage Device
(MSD).
3. See Using the USB Connection for IDRaman mini Library Building for directions to copy library
files to the IDRaman mini.
4. Disconnect the system from USB drive and reconnect. The system will now use the library files
that you created.
Note
If you do not disconnect and reconnect, the system will continue to act as an MSD and it
will not use your library to match.
If you intend to encrypt your files, you will need to use the Secure Library function when you are ready to
place them on the IDRaman mini. See
Building a Secure Library .
Acquiring a Reference and Spectrum
Spectra can be acquired several different ways depending on your application or on the sample’s
composition.
Button Function
Acquire Acquires a spectrum for the integration time. The laser turns on for a period of time
determined by the integration time. Some delays exist to allow for the laser
stabilization; however, the exposure time is precisely set by the integration time
selected.
Reference Acquires a dark reference for the set integration time. Normally the shutter closes
during this period and the reference spectrum is subtracted from the acquisition.
This removes any environmental background and it eliminates any fixed pattern
noise due to the CCD detector.
The slide switch at the top: Use Reference determines if a reference is used. Use
Reference (Yes) causes the reference to be subtracted; this is the default. Select
Use Reference (No) if you do not want the reference subtracted.
NOTE: It is essential to have the reference acquired for the same integration time as
the acquisition. If there is a mismatch, a new reference will be automatically
acquired at the new acquisition time.
