Software Instruction manual
3.1
General
The purpose of this Section is to provide training on the acquisition and viewing of
spectra. This application can acquire information at timed intervals ranging from
1/10 of a second to hours. In order to establish the best possible integration time, the
spectroradiometer application is equipped with an “Optimize Integration Time”
function. This function searches for the best integration time for the intensity of the
incident light.
In order for the spectroradiometer application to be able to acquire data, it needs to be
connected to the spectroradiometer instrumentation. However, it can be used
independently to view previously acquired files. The application also requires that
the LabVIEW
run time engine
be loaded in the computer in use. The LabVIEW run
time engine is provided in the installation package.

Software Installation
3.2.1
On a computer already having the spectrometer driver:
You may
already have a driver installed for the hardware. If this is the case, all you
need to do is install the application. Insert the CD into the CD-ROM
drive. A setup application should automatically appear. If it does not,
locate the folder named Spectroradiometer v2.2, open the “Installer”
folder, and install the application. The setup application will install both
the LabVIEW run time engine as well as the application. Once the
installation is complete you may need to restart your computer.
3.2.2
On a computer with no spectrometer driver:
In this case you need to
install both the application, and driver for the hardware
.
Modern
operating systems such as Win XP will automatically detect new hardware
and search for an appropriate driver. The driver for the hardware is
