Light settings
To get the best results, we recommend using this application with the
TAGARNO FHD Trend. This allows you to attach the right accessories
and rightfully adjust the settings.
Equipment needed:
Ring light white
Basic or Advanced control box (external lighting)
White balance calibration card
White balance calibration card xture
Sample drawer
Sample drawer positioner
Light eliminator
This enables the app to run objective and reproducable analyses.
The microscope light settings are automatically set to auto exposure.
Step 1
Mount a Ring light white from TAGARNO on the microscope as
described in the TAGARNO Ring light white user guide.
Step 2
Adjust the light settings to the right intensity using the advanced ring
light control box.
Step 3
Place the Light eliminator over the camera head as displayed below
and close the Light elimator by pulling the backwall all the way up. Do
not forget to tighten the screws to prevent the backwall from falling
back down. Using the Light eliminator will eliminate any external light
and prevent it from interfering with the analysis result.
Step 4
Run a white balance calibration (see Toolbar section, pt 4).
Step 5
Pour sample into the Sample drawer, insert it in the Sample drawer
positioner and pull the Light eliminator all the way down using the
handles as shown below.

 1.Magnicationlevel
Use a keyboard or the control box to choose magnication
level. You should only see the sample, not the sample
drawer or sides of the light eliminator.
 2.LiveView
Use this button to toggle between live and snapshot,
In Live mode, the live camera image is active. In Still Image
mode, the latest snapshot will be shown.
 3.Snapshot
Use this button to take a snapshot of the live image.
The snapshot will not be saved automatically. The
snapshot is used for toggling between “Live and Still Image
mode”.
 4.Whitebalancecalibration(WBC)
Perform an automatic white balance adjustment in order to
get colors displayed correctly on screen.
NB! It is recommend to leave the microscope turned on for
30 minutes before performing the WBC.
Place the White balance calibration card in the allocated
slot on the Calibration card xture and place them both on
top of the Sample drawer as shown below.
Then, insert the sample drawer with calibration card xture
and calibration card into the sample drawer positioner and
press the white balance calibration button on the monitor
to start the calibration.
A white balance calibration is made each time the camera
is turned on to adjust to the given light conditions. A white
balance calibration must also be made every time the light
conditions change.
NB! If the Sample drawer with calibration card and
White balance calibration card xture is not inserted
into the camera eld of view when the unit is turned
on, the white balance will be incorrect and it will be
necessary to perform the white balance adjustment
process as described previously.
NB! Once the WBC has been performed, place the White
balance calibration card into its UV protection sleeve.
Storing it in the sleeve will prolong the life expectancy of
the White balance calibration card.
 5.SaveImage
This button provides the possibility to save the current view
with graphics. When activated, the information panel
will also appear from the saved image (see pt. 15).
When saving an image, an information window will appear
for a few seconds showing the le name and storage
location.
The image will be saved on the inserted USB memory stick.
If a USB memory stick is not attached, the image is saved
internally on the microscope, provided the share le mode
is turned on in General settings.

Choosevalues
Choose a value by sliding the bar with the mouse or typing in the
number eld by using a connected keyboard.
6.Brightnesslter
Use this slider to eliminate brightness that should not be included
in the analysis. The more brightness that should be ltered out, the
further to the right the slider should go.
7.Darknesslter
Same principle applies to this slider. Dark areas in your sample (e.g.
shadows between the peanuts) can be ltered out by moving the
slider to the right.
8.Samplesize
Dene how many sample images the analysis must be based on.
9.Scalerange
Dene the scale range for the overall table. Insert a number in the
min. and max.
10.Passlimits
Dene the min. and max. pass limits for the desired product. These
values must be within the dened scale range.
11.Faillimits
Dene the unacceptable scale range in the sample by typing in the
min. and max. color value. The min. value must be between the min.
scale value and the min. pass limit. The max. value must be between
the max. scale value and the max. pass limit.
12.Savetemplate
• Click once on the star symbol to save a template using the
current zoom level, slider positions and color values
• State preferred name and press save
The template is now saved and available for later use.
13.Recalltemplate
Recall a saved template by clicking on the list and choosing the
template of your choice.
Delete a template by pressing the X at the right of each saved
template.
14.WhiteBalanceCalibration
Perform a white balance calibration in order to get colors displayed
correctly on the screen.
Read more about white balance calibration in section 4.
15.Informationpanel
Activate this information panel to view all details of template, lter
settings, scale range, pass limits and fail limits, close up lens and
analysis results.
Disable the information panel by pressing the icon again.
16. Reset Data
Reset data to delete previous analyses from the result overview (see
next page).
17.Runanalysis
Choose this option to run an analysis of the current image and get
indications of the actual color value of the sample.
The analysis will always be performed using a still image which is
automatically captured during the analysis process.
NB! You will not be able to run the analysis, if the button contains a
yellow exclamation point. Perform a white balance calibration before
trying again (see pt. 4).

ColorAnalyzerresult
When an analysis has been performed, the results will be
displayed on the left side of the monitor as shown below.
The average color value of the sample is written on the screen
and displayed on the dened color range (top left corner) in
green if within the dened pass limits. Standard deviation is
also counted.
All identied color values within the dened color range is
displayed on a graph. Values within pass limits are displayed
as green, while values close to or within fail limits are displayed
as yellow. Values outside of the fail limit range are displayed
as red.
Previous analyses are displayed on a table for easy
comparison between samples. Clear this table using the Reset
data button (see pt. 16).
Use the Snapshot function on the control box to capture an
image of your analysis result. For more info, read Operation
section in the user guide for your TAGARNO FHD digital
microscope.
