functions for scanning, recording, features, options and general use of the
software are identical for both methods of operation and are covered
jointly in detail next.
It should be noted that the reason for using the bench unit is to increase
accuracy and eliminate variables. The bench unit provides a much more
controlled environment as any laboratory device should. Elimination of
any variable will almost always increase accuracy and repeatability. For
instance, the bench unit positions the laser in a fixed position both at the
given angle and distance. In addition, the bench unit allows you to
prepare samples more carefully using methods such as leveling.
Although this is not necessary for accurate results, it will increase
accuracy for applications in which a significantly high level of precision
is required.
As already explained, once the device is connected to a computer it is
ready to use. There are some basic concepts in taking samples that should
be observed to insure accurate readings. The device is unique in that it
does not require complex sample
preparation. You can point it at any
angle and virtually any distance
within a foot or two and it will
return consistent results. It should
be noted that consistency in angle
and distance will increase the
accuracy of results. It is

Sample Preparation
The ColorTrack system does not require complex sample preparation but
for best results, consistent preparation methods should be observed and
employed. It is highly recommended that samples be prepared carefully
to avoid contamination or inconsistencies that may skew results. When
preparing your samples, try and prepare a level sample. Most importantly
is to prepare samples in such a way as to insure that the bottom of the
dish or container is not viewed or scanned by the laser as this will affect
results.
recommended that the device be pointed at the sample at a distance of
roughly 2-3 inches and waved slightly over the sample. This allows the
device to read more of the sample and give truer results.
When scanning in real-time, point the device at your sample as described
above and watch the real-time display. As the program averages the
readings it will narrow results to a point where it will not change or
change very little. In other words, when you first start scanning a sample
the resulting values will jump up and down from minimum readings to
maximum readings. Over a few seconds the resulting value will stabilize
through averaging. Once it stops moving up or down in value even as
you move the device around over the sample, you have an accurate
reading
Aside from the real-time readout you may also record a result. Follow
the same procedure to start
scanning and when you are ready
to record, simply press and hold
the red trigger on the front of the
device. The device will continue to
scan, average and record results as
long as the trigger is depressed.
When you have completed your
scan, release the trigger and a static
final result will be displayed
including the average, minimum and maximum reading along with the
standard deviation.
You can save any and/or all of your
recorded results to a database on
your computer that you may also
customize (See “Details Settings”)

Note: Always make sure you release the trigger before moving the device
away or off of the sample or target. Late release of the trigger can cause
the system to read area outside of the sample area.
