Operating Instructions
The CI-203 is a self-contained, hand-held, battery-powered instrument with a built-in display. It
contains an optical scanner to measure leaf width, a roller with a shaft encoder to measure
length, and a microcomputer to coordinate the measurement functions, calculate results, and
store collected data.
Taking a measurement is as simple as turning the instrument on, inserting a leaf into the
objective, and drawing it out. The instrument does the rest.
To turn the instrument on, press the power button. When the instrument powers on, a copyright
notice will appear briefly. Following this, a menu will appear on the display with the following
options: Measure, Setup, View, and File.
Error messages should rarely appear during normal operation of the CI-203. However, in the
event that the display does not show the “Measure” prompt after displaying the copyright notice,
see the Error Message section on page 26.

Note: To force the instrument to restart, press and hold the power button for 10 seconds.
This emergency hard shut-down feature exists to address hardware or software
problems and should not be used except when needed. In general, simply pressing the
Power button in the typical manner will turn off the CI-203.
Note: A file must be created (usually blank) before measurements can be taken. Failure
to do so will hang the system in Measurement mode, requiring a hard shutdown.
Menus and What They Do
The CI-203 menu system allows the instrument to be operated quickly and easily without
repeatedly consulting the manual. Reading the entire manual before performing measurements
in the field is recommended. The screen associated with a menu item will display information
about the choices that can be made or the options that are available. Pressing the right arrow
button will select a menu option and go to the next menu. Pressing the left arrow button will
move the device back to the previous menu screen.

Measure Menu
In measure mode, the top line of the screen will read “Measure” on the left with the name of a
file on the right. The bottom line of the screen will have <arm> on the left, and the four direction
arrows on the right.
The options are:
Select another file with the up or down arrow buttons
Go back to the main menu with the left arrow button
Take measurements by lifting the arm
To start measuring, open the measurement arm until extended completely, and then allow it to
slowly close upon the leaf to be measured. This begins the measurement process. The motor
will start spinning up to speed as soon as the arm opens, and the display will read “Spinning
Up”, “Stabilizing”, then “Arm Open” in quick succession. When the arm closes, the laser will
power on and the display will read “Measuring”. At this point, draw the leaf being measured
through the instrument. When the leaf has been drawn out completely, the instrument will stop
automatically and display the results of the measurement. With “Autosave = Yes”, the
measurement is automatically stored to the currently selected file. With “Autosave = No”, the
user must press the SAVE button to save the measurement to the currently selected file.
The display will show the name of the current file in the upper left-hand corner of the screen and
the measurement number in the upper right-hand corner. Below these, the parameter names
appear on the left and parameter values on the right of the screen.
To bring an image into view, press the right arrow button. Pressing the right arrow button again
will display the barcode data. Pressing the left arrow button from any screen will return the
instrument to the ready to measure mode. To discard the last measurement, press the STOP
button. Now another measurement may be taken, if required. If the automatic save function of
the instrument is enabled, the measurement will be saved automatically.

Setup Instrument Menu
The CI-203 has a number of utility functions that allow the user to manage the instrument’s
capabilities. These functions are accessed by pressing the right arrow when Setup is highlighted
on the main menu. The setup utility options are: Autosave, Measure, Scanner, Storage, Time,
and SD card. Use the up/down arrows to select the desired option, then press the right arrow to
enter the choice.
Setup AutoSave Feature
Pressing the right button when Autosave is highlighted opens the Autosave menu. This allows
the user to setup the instrument to automatically store measurements, and to start taking new
measurements without explicitly saving the old one. This mode is convenient when taking fast,
repetitive measurements or when it is not necessary to review each measurement immediately
after taking it.
In Autosave setup mode, the top line of the display will read “Autosave =” on the left and either
“Yes” or “No” on the right. The bottom line of the display will read <stop>, <save>, and the
directional arrows.

Setup Scanner Thresholds
Note: Normally, there is no need to adjust the threshold of the CI-203 because the
instruments are factory-adjusted to a threshold level that is ideal for all-around use.
The CI-203 automatically adjusts an internal threshold to a level that is optimal for detecting the
presence of a leaf in the scanner objective. If out-of-the-ordinary measurements are being

recorded or if the instrument has suffered from abuse or excessive aging, the manual threshold
setting may need to be adjusted. If the instrument appears to be making incorrect
measurements, make sure the instrument is clean and that the reflective tape and objective
window are undamaged and in good condition. If there is something blocking the optical path in
the scanner, no amount of threshold adjustment will correct the problem. Refer to the Care and
Cleaning section on page 22 for more information on cleaning the CI-203. Please do not
hesitate to consult with the manufacturer or the nearest manufacturer’s representative if there is
a problem and the threshold needs adjustment.
Use the up/down arrow to highlight Scanner in the Setup menu. Next, press the right arrow to
enter the Setup Scanner menu. The options in the Setup Scanner menu include HiThld (High
Threshold), LoThld (Low Threshold), Manual, Filter, and Adjustment. Use the up/down button to
switch between options and the right arrow to select.
Threshold Adjustment (Width Calibration)
In the event that the normal threshold settings need to be altered, perform the following steps.
First, check the threshold of the CI-203 alone, with its arm in place. To do so, access the Setup
Scanner menu, select “HiThld”, then press the right arrow button. The instrument’s motor will
activate, and the “t”and “w”values will appear and count down on the display. Next, the display
will show the high threshold value briefly before returning to the Scanner Setup menu. Make
note of the HiThld value.
Next, select “LoThld”, place a piece of white paper under the arm, then press the right arrow
button. Let the scanner run. The display will show a t value that counts down and w=0. When
the t value is done counting down, the final Low Threshold value (t=) will display briefly before
exiting back to the Scanner Setup menu. Make note of the LoThld value.
Remove the paper from under the arm. Next, select “Manual”from the Scanner Setup menu by
pressing the right arrow button. Make sure that the width reads zero when there is no object
under the arm. Stop the manual scan and the motor by pressing the STOP button. In the
scanner menu, scroll down to “Adjustment”. Here is where the user can adjust the width
measurement based on the high and low threshold values. After increasing or decreasing the
Manual threshold value, press STOP. Press STOP to discard changes or press SAVE to save
any changes that have been made.
<stop>
t = 76 w = 0


The next step is very important: every time the threshold is changed in any mode, switch to the
Measure menu, then press the left and right button at the same time. The instrument will
automatically compute and save the timing parameters. The user should repeat this
computation a few times allowing the instrument to generate an accurate leaf width reading.
Make sure to check the width reading, with and without the filter. When checking the reading
without the filter, the width should be above zero but still a very small value.

for assistance.
Scanner Step Length Calibration
In order to calibrate the scanner step length (step len), from the main menu put the instrument
into Measure mode. Press the left and down arrow buttons simultaneously or press the right and
down arrow buttons at the same time. This will start the length calibration and the user should
be able to see the scanner laser light under the arm, however the motor will not start or spin up.
Slowly draw a piece of white paper (mounted on an opaque, non-reflective surface) of known
length through the scanner several times. The unit will beep during this process. A longer beep
sound indicates a better calibration of the scanner lens. After drawing a piece of white paper
through the CI-203 a few times, push STOP. The lens should now be calibrated. To see the
image and measurement information, press the right or left arrow buttons. Compare known
length to measured length.
Re-computing the CI-203 Parameters
This procedure should be carried out whenever the CI-203’s threshold settings are changed or if
the instrument isn’t measuring accurately. Re-computing the parameters will recalculate the
effects of any changes made on the other parameters.
1. From the Measure menu, press the left and right arrow buttons at the same time.
2. Hold the buttons until the motor begins to spin. The motor should spin for about four
seconds.
3. Do this twice by pressing the left and right arrow buttons simultaneously again and
making sure that the motor spins up.
4. Take a test measurement and try to determine if the Length or Width readings need
adjustment. Are the readings too high or too low?
Setup Scanner Filter
The scanner filter is used to filter out particles on the conveyor cylinder that may be mistaken as
objects to be measured. Press the right arrow when Filter is highlighted to see the current filter
settings and whether it is turned on or off. Use the up/down arrows to increase or decrease the
size of the objects to be filtered out. Press the right arrow to toggle the OFF/ON state of the
filter. Then press the left arrow and press SAVE to choose to save any changes or press STOP
to abort the change and return to the Scanner menu.

Setup Storage (SPI Flash Management)
SPI (serial peripheral interface) flash plays an important role in the architecture of the CI-203. It
holds all the non-volatile scan parameters, copy file descriptors, measurements buffers, etc. The
total size of the serial flash is 1 MB, or 16 sectors, with 64 KB in each sector. Currently the
CI-203 uses four sectors; sector 0 is inerasable while sectors 1-3 can be erased in the Setup
Storage menu. Sector 0 is protected because it holds all of the scan/timing parameters. The
user is allowed to modify these parameters, but not to erase them. Sectors 1-3 can be erased,
eliminating all the files from the CI-203.
Note: The user must create at least one (usually blank) file or else taking a measurement
will cause the system to freeze, requiring a hard reset.
When the user creates a file, the instrument allocates data structure at sector 1 of the serial
flash. In addition to this, the same file is created on the SD card. This is necessary because the
CI-203 uses only special files with the removable SD card. Without the SD card inserted, the
instrument is still able scan an object, but cannot store or save the measurement.

Format Storage
Pressing the up/down button switches the display to the format storage mode screen.
Note: Formatting the storage space of the CI-203 will erase all data and all files. This is
convenient when starting a new year’s work but treat this command with care.
In format storage mode the top line of the display will read “clear all data”. The bottom line of the
display will have the word <stop> to the left and <enter> to the right.

Barcode Data
The barcode data display screen shows barcodes that contain information about the
measurement. The barcodes contain the values for the area, length, width, and perimeter in
order from top to bottom. Use a barcode scanner or other device that can scan barcodes to read
the data displayed in the barcode data display.
View GPS
The new CI-203 has a built-in GPS system which can relay the longitude, latitude, and altitude
of the instrument when performing measurements. The figure below shows the GPS menu
display. The GPS uses GMT or Greenwich Mean Time for a standardized time. The GMT is
displayed as the time (TIM) on the GPS menu and is synchronized with minute and second
alignment. Often when the instrument is turned on indoors, the latitude, longitude, and altitude
will read “NOFIX”. This occurs when no satellite signal can be obtained by the instrument.
Powering up the CI-203 outdoors will correct this problem and allow latitude, longitude, and
altitude readings to be taken along with leaf measurements.
Other View Menu Options
Besides viewing saved data and files, voltage, remaining battery power, GPS location, time
stamp (time and date), and the properties of the SD card can be checked from the View menu.

The View Time screen displays the current time on the instrument. The View GPS screen
displays the current GPS values for latitude, longitude, and altitude and it indicates the number
of satellites it is currently connected to. Press the up/down arrow to display more GPS
information. The GPS may read “NOFIX” if the instrument is located indoors and cannot connect
with a satellite.
The View SD card screen indicates if an SD card is present in the unit. If no SD card is in the
instrument, or if the SD card is not fully inserted, “No” will appear on the display.

File Menu
The File menu is accessed by highlighting “File” on the main menu and pressing the right arrow
button. Here, the user can manipulate files on the CI-203, with options to clear, delete, create,
and open files.
The CI-203 uses an SD card to store all measurements. This means the user is able to create,
clear, and delete any measurement file. The instrument uses a regular FAT32 file system to
access stored data.
To view data on a computer, simply connect the instrument to the USB port on the computer
with the USB cable included or insert the SD card into the computer’s SD card reader. The
computer should automatically detect the SD card as a new storage device and mount the drive
so that measurement data will be accessible by any computer application. When the user
creates a file to store data on the computer, the same file name created on the SD card will be
used, with the file extension .img. The image file is used to store synthesized images for each
measurement.
Clear a File
Pressing the right arrow button when “Clear”is highlighted on the display allows the erasure of
the file contents without changing its name or its setup. This feature is useful if it is necessary to
do a number of similar measurements. The user can take these measurements to a particular
file, copy the results, clear the file, and be ready to take a new set of measurements using that
same file.

With “Clear”selected, press the right arrow button to open the View File Clear menu. Use the up
and down arrow buttons to select the file to clear. Press the right arrow button to clear the file.
The display will indicate “Done!” when the file contents are erased and will return to the View
File Clear menu. Press STOP to go back to the File menu.
Delete a File
With “Delete”selected, press the right arrow button to open the View File Delete menu. Use the
up and down arrow buttons to select the file to delete. Press right arrow button to delete the file.
The display will indicate “Done!” when the file is deleted and will return to the View File Delete
menu. Press STOP to go back to the File menu.
Create a File
Press the right arrow when “Create” is highlighted on the display to get the unit into 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 left/right arrows
appear on the right.

Note: The STOP button can be pressed at any time to abort the file creation process and
to return to this point.
Pressing the arrow buttons will allow the user to select an alphanumeric character for a
six-character file name. The right/left arrow buttons select which character in the file name to
edit and the up/down arrow buttons are used to choose a character. The chart below lists the
available characters.
Warning: Do not use the following characters, they are not allowed in file names.
Pressing the SAVE button while editing a filename deletes that character position. Note that the
cursor position is represented by a reverse character display. Characters cannot be inserted
into an existing file name.
Once the desired filename has been selected, press ENTER. The next screen toggles through
the test names with the right and left arrow buttons and toggles “yes”and “no”with the up and
down arrow buttons. This has no effect on the measurements; all parameters are tested on
every measurement.
The user should just press ENTER to bypass this screen.
Should the file name be identical to another file name, the instrument will display the message
“duplicate name” and <enter> on the two top lines of the display.
The CI-203 will save all parameters for each measurement (width, length, perimeter, area,
aspect ratio, and shape factor) on the SD card. Use the left/right arrows to scroll through the
parameters and the up/down arrows to include or exclude parameters. Once finished creating
