OPERATING INSTRUCTIONS
The CI-202 is a self-contained, hand-held instrument with a built-in display and batteries. It contains an
optical scanner to measure width,.
Taking a measurement can be as simple as turning the instrument on, inserting a leaf on the scan board, and
scanning. The instrument does the rest.
To turn the instrument on or off, press the ON/OFF button. When the instrument comes on, a copyright
notice will appear for 1/2 second. Following this, several words will appear on the display with the word
“Measure” appearing in the upper left-hand corner of the display. You are now in the CI-202 menu system.
NOTE: When there are no files to store data to, the measure menu items will not be available.
To correct this situation, create a file.
The following sections describe the menus and what they do. The CI-202 menu system allows you to
quickly and easily operate the instrument without constantly referring to this manual. Whenever possible,
the screen associated with a menu item will give you information about choices that you can make. Usually,
the top line of the screen will contain information about where you are, and the bottom line will contain
information about buttons to press to change the current status.
Measure
In the measure mode, the top line of the screen will show the word “Measure” on the left, and the name of a
file on the right. The bottom line of the screen will have the word “start” in brackets on the left, and the four
direction arrows on the right.
Measure file00
<start> 
The options are:
to select another mode with the up or down arrow keys
to select another file (if there is more than one file) with the right or left arrow keys
to take measurements
To start measuring, hit the enter key or the start key. This begins the measurement process. The motor will
start spinning up to speed as soon as the button is pressed, and the display will read “Stabilizing”, then
“Spinning Up”, then “Measuring”. At this point, move the scan head down the scan board. When the scan
head has been drawn out completely, the instrument will stop automatically and display results of the
measurement. At this point, preview the results, and decide whether it should be saved and to which file it
should be saved to. The enter key will cause the scanner to start and then the instrument will start
measuring; if motion is not detected within a few seconds, the scanner will shut down. The start key does the
same thing, but if it is held down, the scanner keeps spinning until you are ready to measure.

area = 44.04 cm2
NOTE: Because of the amount of information displayed on this screen, the CI-202 cannot display any
prompts in this mode.
To bring another parameter into view, press the RIGHT or LEFT arrow key. Repeatedly pressing the right
arrow key will step you through area, length, width, perimeter, aspect ratio and shape factor, in that order.
Only parameters that can be saved to the current file will be displayed. If changes are required before data is
saved, use the up and down arrow keys to step through the files. To discard the measurement, press the
STOP button. Another measurement may be taken at this time, if required. Depending on the set-up of the
automatic save function of the instrument (see Set-up Auto Store parameter section in the main section of
this manual) the measurement will or will not be saved.
To save the measurement, press the SAVE button. If the instrument is able to save this measurement, the
word “saved” will flash on the bottom line of display to confirm the data saved. If there is insufficient
storage space to save the measurement, the instrument will flash the message “no room!” on the bottom line
of the display.
View Data
In the view mode, the top line of the display will show the word “View” on the left and the name of a file on
the right. The bottom line will show the word “enter” on the left and the four direction arrows on the right.
View file00

Once you have selected a file to view and pressed the ENTER button, you will be able to look at the data in
the file. The top line of the screen will have the file name at the left. Press the UP arrow to see the word
“total” on the right and the total of all areas. Press the UP arrow again to see the average.
file00 total
area = 345.0 mm2
Note: Because of the amount of information displayed on this screen the CI-202 cannot display any
prompts in this mode.
One of three things will be displayed: the most current measurement sequence number, the average of all
measurements, or the total of all measurements. The bottom line will display the parameter name on the left
side and the parameter value on the right side.
To bring another parameter into view, press the RIGHT or LEFT arrow key. Repeatedly pressing the right
arrow will display area, length, width, perimeter, aspect ratio and shape factor in that order. To bring
another measurement into view, press the UP or DOWN arrow key. Pressing the UP arrow key will display
the total values for all measurements in the file in the following order: The first value shown is the average
value for all of the measurements in the file, the most recent measurement in the file and on through the first
measurement taken. Next, return to the total again. Think of this view mode as a computer spreadsheet that
only allows the user to view one cell at a time.
To return to the main view mode, press the STOP/RESET key.
To view battery life, arrow right or left until “View Battery” is displayed. Hit enter and it will display
battery life left.
Manipulate Files
The CI-202 gives an expanded ability to organize data collection by using a file structure similar to that used
by personal computers. The CI-202 has up to 256 files available. Select a unique name for each file to
control the data stored in each file to optimize the amount of data stored for research that is carried out.
The file mode capabilities are: Clear, Delete, Create, and Close files. While in the file mode, the top line of
the screen will read “files” on the left and one of the words “Clear”, “Delete”, “Create”, or “Close” on the
right. The bottom line of the display will read “enter” on the left and the four direction arrows on the right.
The options are:
to select another mode, use the up or down arrow keys
to select a particular action to carrying out on files, use the right or left arrow keys
to start the selected action, use the START/ENTER key

To delete a file, use the UP or DOWN arrow keys to select a file. Once a file is selected to be deleted, press
the START/ENTER key. The instrument will confirm the deletion with the line “<erase> <stop>”. To
delete the file, press the SAVE key. To escape without deleting the file, press the STOP key.
Create a File
When the START/ENTER key is pressed, “Name: Files” is displayed on the top line, indicating the unit is
in create files mode. The top line of the screen will read “Name” on the left, and a file name (e.g. “file00”)
on the right. The bottom line will read “enter” at the left, “erase” at the center, and the four direction arrows
at the right.
Name: file00
enter erase 
NOTE: The STOP key can be pressed at any time to abort the file creation process and to return to this
point.
Pressing the arrow keys will allow an alpha or numeric selection for a six-character file name. The right and
left arrow keys select which character in the file name to edit and the up and down arrow keys are to choose
a character. The chart below lists the available characters.
! " # $ % & ' ( ) * + , - x / 0 1 2 3 4 5 6 7 8 9 : ; < = > ?
@ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ ¥ ] ^ _
Pressing the SAVE/ERASE key in the "Create files" mode deletes the character under the cursor. Also,
characters cannot be inserted. After naming the created file, press the START/ENTER key twice to
continue the file creation process by entering Parameter Set-Up. Should the file name be identical to
another file name, the instrument will display the message “duplicate name” on the top line of the display
and “enter” on the bottom. All the data is stored no matter what the YES/NO flag is set to for area, length
width, perimeter, ratio, and factor. If the Root Length flag is set to YES, then only length is stored, but the
record length and number of measurements possible is unchanged.
When entering file Parameter set-up, the top line of the display reads the name of a parameter at the left and
the word “yes” or “no” at the right. This indicates whether the particular parameter will be flagged for
display. The bottom line of the display will read “enter” at the left and the four direction arrows at the right.
Note: “Root Length” Parameter must be set to “No” when “Setup Measure” mode is set to measure
“Leaf.”

Use the up or down arrow keys to modify the value. Once satisfied with the set-up parameters, press the
SAVE key. To avoid saving the parameters, press the STOP key to abort the process.
Set-Up Scanner Thresholds
NOTE: Normally, there is no need to adjust the threshold of the CI-202 because the instruments are
factory-adjusted to a threshold level that is ideal for “all-around” use.
Manual Threshold Adjustment
First, adjust the threshold with the CI-202 over the reflective tape of the scan board. Select “Setup Scanner”
in the display window and press START. Select “HiThrld” and press START again. Write down the
threshold value displayed. Place a piece of white paper so it covers about half of the laser scan area starting
at the right hand side (away from the rail). Select “LoThrld” and press START. Again, write down the
threshold value displayed.
First, calibrate the instrument alone with the instrument over the reflective tape of the scan board. Select
“Setup-Scanner” from the menu, then select “Manual” and press ENTER. The motor should spin and the
laser should come on. The display should show something like this:
T = 47 w = 0
<stop>
The “t” value is the threshold and the “w” is the width (in pixels) that the instrument is reading. Use the
up/down arrows to adjust the “t” value to 10 above the LoThrld value you wrote down above. The HiThrld
value must be at least 15 more than the new “t” value.
Press STOP to shut off the laser and motor, press STOP again and press SAVE if you want to keep the new
threshold. Press the down arrow to get back to the Measure display. Press both the left and the right arrows
at the same time. The CI-202 will turn on the laser for a short period while it measures the width. Press the
up arrow and then the ENTER key to get back into the setup scanner menu. Press the SAVE and STOP keys
at the same time. A new display will appear that allows you to see the precharge and other factory settings.
Do not make any changes to these settings. Press STOP and then STOP again. The instrument will ask Save
changes? Press SAVE. Test the instrument to see if it is working.
If the instrument malfunctions after manual threshold adjustment, contact CID, Inc. for assistance.
