Prior to enabling the colorimeter ensure that you have
saved a dark reference and a white reference (such as
with the RS50 white standard)while in the Scope Mode.
This ensures that your spectrometer is
performing correctly with NO light and White light
using your reflectance probe or integrating sphere.
For the best results using a reflectance probe, use a
fixture that holds the tip at the same distance from
each sample (like the RPH1 reflectance probe holder).
When using the fiber probe, hold it at 45 degrees to the
sample about 1/4 inch from the surface. Make sure that
the bell curve response viewed does not saturate at the top
peak. If it does then you should either adjust the detector
time or adjust the sample distance. Use a fixture to hold
your probe about 1/4 inch from the sample (at 45 degrees)
for the best results.
You may then enable the CIELAB Color Monitor application.
The New Reference button allow you to take a "standard
white" re-reference at any time. This should give
an L value of 100 in the bar graph. Most all of the
SpectroColorimeter buttons are self explanitory.
Save sample allows you to rapidly record samples into
a "colordata.log" file for subsequent viewing or printing.
The save standard allows a particular sample to be loaded at
a later time to compare with other samples. The Delta E*
is the square root of the sum of the squares of the L* a* b*,
and is used to determine if another sample is similar. If
Delta E* is 3 or greater, then the test sample is considered
a different color as compared to the selected standard.

ChemWiz Methods
///////////////
ChemWiz allows users to setup and use methods for predicting
chemical concentrations. To use this application you will need
to have an accessory configuration for measuring liquid (or gas)
chemicals in a cuvette, or a dip probe, or a flow cell. When
a method is setup, a known maximum concentration is measured at
a specific wavelength and a calibration curve is then stored.
The number of user configurable methods is unlimited.
Once a method has been configured, it can be opened to operate
in real-time. SpectraWiz automatically sets all the system
parameters required by the specified method. This includes
detector integration time and all parameters found in the setup
menu. When activated, it will begin to display concentration
values. It is important to setup for and press the Zero
Reference button. This requires the sample to contain the
solvent solution or zero percent concentration. It is a good
idea to perform a Zero Reference as often as possible when
a second specto channel is not available for automatic lamp
