Use your F-750 Produce Quality Meter to
measure the contents of brix or Total Soluble
Solids (TSS), Dry Matter, Titratable Acidity,
internal color, external color, and many other
user-selectable traits in a range of materials
and commodities.
Your F-750 comes with pre-programmed
demo models for:
• Apples
• Grapes
• Kiwi
• Mandarins
• Mangoes
• Pears
• Persimmons
Try these models to familiarize yourself
with the F-750 and to begin making relative
measurements right out of the box.
For precise measurements, create a custom
model using the Quick-Start Guide: Model
Building procedure on the following page.

The Model Building process is meant to enable the user to calibrate the
instrument to their specic commodity. This process will result in a model
which can then be used continuously on the F-750 for non-destructive
measuring. This Model Building Quick Start Guide is meant to serve as
an overview to the entire process. This document is supplemented by other
training resources, like Training Slides and Training Videos. Please visit
www.felixinstruments.com/support/F-750 to obtain these materials or
e-mail [email protected] for further questions.
1. Gather your samples
Aim for a broad range of maturities, varieties,
or both.
• The range should represent
maturation stages the user will
want to evaluate.
• A good range will have a standard
deviation of greater than 2 values
from the mean.
2. Create a training set and scan your
samples with the F-750
• Scan a uniform unblemished portion
of flesh.
•When first building a model, it is
recommended that you build the
model using fruit at room
temperature only. Temperature
compensation can be built into the
model at a later point.
Please see the F-750 User Manual
for more details.
Video guidance for this step can be found at:
www.felixinstruments.com/support/F-750/video
as “F-750 Model Building - Part 01 - Building
the Training Set” and “F-750 Model Building -
Avocado” and in the User Manual under
“Creating a Training Set”.
3. Destructively measure your samples
to obtain reference values
Your model results depend greatly on the
accuracy of your reference method!
• The reference values will not be
taken with the F-750.
• The reference value will be taken
from the exact location of the scan,
not the whole fruit!
• For each sample of fruit, there will
be one representative reference
value.
Video guidance for this step can be found at:
www.felixinstruments.com/support/F-750/video
as “F-750 Model Building - Part 01 - Building
the Training Set”.

4. Load your training set and
reference values into the
F-750 Model Builder software
• Select ‘import’ to load the training
set le into the ‘training set’ tab
from the F-750 SD card.
•Import or paste your reference values
into the ‘reference values’ tab.
• Ensure your specimen numbers
match-up between the ‘training
set’ and the ‘reference values’ tab!
Video guidance for this step can be found at:
www.felixinstruments.com/support/F-750/video
“F-750 Model Building - Part 02 - Using
Model Builder”.
5. Build a model and save it
• Select ‘build’.
• Review your results in the ‘model
performance analysis’ tab.
• Select the number of principle
components you wish to use for
the nished model.
• Hit “Save” to successfully
complete the new model.
Guidance for this step can be found at:
www.felixinstruments.com/support/F-750.
See the FAQ: “How do I Determine Model
Quality?” and the User Manual under
“Using the Model Performance Analysis Tab”.
6. Load the model onto the F-750
• The model must be loaded onto
the SD card in the ‘models’ folder.
• Power on the instrument.
• Right arrow to select your model
and begin taking scans!
7. Validate your model by scanning
more fruit
•Now you’re ready to scan additional
fruit to validate your model!
• Scan several specimen.
•You can then use your selected
reference method (used to calculate
Reference Values in step 3) to verify
that the values displayed on the
F-750 are accurate.
Guidance for this step can be found in the
User Manual.
