Select Model
There are three options available from the Select Model Menu: none, Apple DM and TSS, and Mango
DM and Colour. Use the up/down arrows to highlight the desired selection. Once it is highlighted, the
model is loaded. To make modifications to the model, press the right arrow when the model is
highlighted to get to the sub-menu.
Several parameters can be modified using the select model sub-menu, such as the integration time and
scale coefficient 1 and scale coefficient 2. The Integration time menu allows the user to switch between
auto integration time and manual integration time. When “disabled” appears next to auto-integration
time, the integration time values can be set manually. Only when the auto-integration time is disabled
are the options to adjust the integration time turning the lamp on and off will appear.
Using the scale coefficient 1 and scale coefficient 2 menus, a new value to use for the scale coefficient
can be entered. The scale coefficient is from the regression vector.
Press the left arrow to get back to the sub-menu. If the left arrow is erasing characters on the display,
keep pressing the left arrow to erase all the characters and then it will exit to the previous menu.
Browse Records
The data saved by the F-750 is referred to as a record. Each record has different parameters saved in it,
depending on the model used when taking the measurement. For example, if using the mango model,
the record will contain values for dry matter, color and chlorophyll. The apple model contains dry
matter (DM) and total soluble sugars (TSS).
Press the right arrow to enter the File menu. The options from the file menu are view spectra, file
details, rename record and delete record. From view spectra, three options are available: reflectance,
absorbance and 2
nd
derivate absorbance. Select an option by highlighting it. The F-750 will render it
and display a graph of the spectra. File details contains information about the file, such as the name and
model.
