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 in the objective, and
drawing it out. The instrument does the rest.
Figure 1. CI-203 Laser Area Meter
To turn the instrument on, press the power button. When the instrument powers on, a copyright
notice will appear for 0.5 seconds. Following this, a menu will appear on the display with the
following options: Measure, Setup, View and File. You are now in the CI-203 menu system.

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 of this manual.
Note: To force a power off and reset of the instrument at any point, a user may 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 power off the CI-203.
Note: User must create a file (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 you to quickly and easily operate the instrument without repeatedly
consulting the manual. It is recommended to read through the entire manual with the instrument
before performing measurements in the field. The screen associated with a menu item will give you
information about the choices that you can make or the options that are available. Pressing the right
arrow or forward key will select a menu option and move you to the next menu. Pressing the left
arrow or backward key will move you back to the previous menu screen.
MEASURE MENU
In the 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 the word “arm” in brackets on the left, and the
four direction arrows on the right.
Measure file00
<arm> 
The options are:
to select another file with the UP or DOWN arrow keys
to go back to the main menu with the LEFT arrow key
to 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”,
and “Arm Open” in quick succession, then “Measurement” near the top line. 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 ‘Autofile’ = ON, the measurement is
automatically stored to the currently selected file. With ‘Autofile’ = off, 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
sequence number of the measurement in the upper right-hand corner. Below these the parameter
names appear on the left and parameter values on the right of the screen.
Figure 3. CI-203 display read out and key pad
To bring an image into view, press the RIGHT arrow key. Pressing the RIGHT arrow key again will
display the barcode data. Pressing the LEFT arrow key 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. Depending on the setup of the automatic save function of the
instrument, the measurement will or will not be saved.
Figure 4. Image of measured leaf on CI-203 display screen
To save the measurement, press the SAVE button; the word “saved” will be shown near the top line of
the display to confirm that the data is saved. Make sure the SDcard is present when saving data to a
file. The user may verify and transfer files by connecting the instrument to a computer using the USB
port on the CI-203, or by mounting the SDcard into the SD slot on the computer and using it as a local
drive; then open the file explorer to view the files. Files should be copied from the SDcard and saved
to the hard drive before proceeding with any calculations or data manipulation.

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 SDcard.
Use the UP/DOWN arrows to select the desired option and then press the RIGHT arrow to enter the
choice.
Setup AutoSave Feature
Pressing the RIGHT key when Autosave is highlighted enters the Autosave feature. This allows the
user to setup the instrument to automatically store measurements, and to start a new measurement
without explicitly saving the old one. This mode is convenient when taking fast, repetitive
measurements as well as when it is not necessary to review each measurement immediately after
taking it.
In the 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” and “save” and the
directional arrows.
Autosave = yes
<stop> <save> 
To set the instrument up to automatically store measurements press the UP/DOWN arrow key until
the word “yes” is on the display, then press the SAVE key to save the configuration. To set the
instrument up to automatically discard measurements, press the UP/DOWN arrow key until “no” is on
the display, then press the SAVE key to save the configuration. To avoid changing the configuration,
press the STOP key to exit back to the Setup Menu.
Setup Measure
Pressing the RIGHT key when Measure is highlighted enters the Setup Measure mode. Here the user
can switch between Leaf and Root mode using the UP/DOWN arrows. For instructions to access
Conveyor mode, see Appendix I of this manual. Press SAVE when the desired mode is on the display.
Press STOP to go back to the Setup Menu.
The Measure Leaf mode is the regular mode for doing leaf measurements using the CI-203 and the
arm. When the instrument is in Root Mode, the arm is removed and the instrument is used in
conjunction with the CI-203RL root length tray accessory. Please see Appendix II of this manual for
more information about using the CI-203 in Measure Root mode.

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 optimum 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 the reflective tape and the objective window appears to be 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 section on cleaning and maintenance for more
information on insuring that the instrument is clean. Please do not hesitate to consult with the
manufacturer or with the nearest manufacturer’s representative if there is a problem and the
threshold needs adjustment.
Use the UP/DOWN arrow to highlight Scanner on the Setup Menu display. Next, press the RIGHT
arrow to enter the Setup Scanner menu. The options on the Setup Scanner menu include HiThld
(High Threshold), LoThld (Low Threshold), Manual, Filter and Adjustment. Use the UP/DOWN key to
switch between options and the RIGHT arrow to select.
Threshold Adjustment (Width Calibration)
In the event you need to alter the normal threshold settings, 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” and press the RIGHT arrow key. The instrument’s motor will turn on and a “t”and “w”
value 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, switch to “LoThld” menu and place a piece of white paper under the arm and press the RIGHT
arrow key. 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 key. Make sure that the width reads 0 when there is no object under the
arm. Stop the Manual scan and the motor by pressing the STOP key. On 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.
You will be prompted to STOP (discard changes) or SAVE changes if you made any.
The next step is very important: every time the threshold is changed in any mode, switch to the
“Measure” menu and press the LEFT and RIGHT key 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 0 but still a very small value.
t = 76 w = 0

If the instrument malfunctions after manual threshold adjustment, contact CID Bio-Science, Inc. for
assistance.
Calibration of the Scanner Length
In order to calibrate the scanner step length (step len), from the main menu put the instrument into
‘Measure’mode. Push the LEFT and DOWN arrow keys simultaneously, or press the RIGHT and DOWN
arrow keys 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 while you do this. 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 keys. Compare known length to measured length.
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 select Save to choose to make the change or Stop to abort the change and
exit back to the Scanner Setup menu.
Setup Scanner Adjustment Menu
Press the RIGHT arrow when ‘Adjustment’is highlighted to get to the Setup Scanner Adjustment Menu
which provides access to precharge, scan width, scan time, step length (step len) and scanner defaults.
Press the RIGHT arrow to access the ‘Precharge’setting and press ENTER to spin up the motor. Press
LEFT or STOP to stop the motor or to exit back to the Scanner Setup Adjustment Menu. Use the
UP/DOWN arrow to change the precharge value in the upper right corner.
Precharge should be at 85
First 2 digits should be 14
At the ‘Scan Width’selection, press the RIGHT arrow to start the motor spinning up. Press LEFT or
STOP to stop the motor or to exit back to the Setup Scanner Adjustment Menu. Use the UP/DOWN

Press the RIGHT arrow to access the Scan Defaults menu. Press ENTER and indicate whether you
want to save the defaults by pressing the SAVE key or press STOP to exit. Press LEFT arrow to exit
back to the Setup Scanner Adjustment 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, the copy file descriptors, the measurements buffers, etc.
The total size of the serial flash is 1MB, or 16 sectors with 64KB in each sector. Currently the CI-203
uses 4 sectors; sector 0 is inerasable while sectors 1-3 could be erased by the user from the "Set-Up
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 could be erased thus
eliminating all the files from CI-203.
The user must create at least one (usually blank) file or else the “Measure” function will hang
the system 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 SDcard. This
is necessary because the CI-203 uses only special files with the removable SDcard. Without the SDcard
inserted, the instrument is still able scan an object, but cannot store or save the measurement.

GPS System Features
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 “no fix.” 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.
Figure 5. CI-203 GPS menu
Other View Menu Options
Besides viewing saved data or files, you can also check on the voltage, battery power remaining, GPS
location, time stamp (time and date) and the properties of the SDcard from the CI-203 View Menu.

Menu.
The View Voltage screen shows the current voltage of the instrument and the View Battery displays
the percent battery life left. If any of these numbers are rapidly changing after the instrument has
warmed up, please contact technical support at [email protected].
The View Flash option is only accessible by CID Bio-Science technicians.
The View Time screen displays the current time on the instrument. The View GPS screen displays the
current GPS values for latitude, longitude, altitude and indicates the number of satellites 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 SDcard screen indicates if an SDcard is present in the unit. If no SDcard is in the instrument,
or if the SDcard is not fully inserted, “no” will appear in the display next to SDcard.

FILE MENU
The File Menu is accessed by highlighting “File” on the Main Menu and pressing the RIGHT arrow key.
Here, the user can manipulate files on the CI-203, with options to clear, delete, create and open files.
The CI-203 uses an SDcard 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 SDcard reader. The computer should
automatically detect the SDcard 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 SDcard 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 key when ‘Clear’ is highlighted on the display allows the erasure of the file
contents without changing its name or its set-up. 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, the RIGHT arrow key will take you to the View Files menu. Use the UP or DOWN
arrow keys to select the file to clear. Press the RIGHT arrow key to clear the file. The display will
indicate “Done!” when the file contents are erased, and you will be returned to the View Files menu.
Press STOP to go back to the File Menu.
Delete a File
With ‘Delete’ selected, the RIGHT arrow key will take you to the View Files menu. Use the UP or DOWN
arrow keys to select the file to delete. Press RIGHT arrow key to delete the file. The display will
indicate “Done!” when the file is deleted, and you will be returned to the View Files 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 the 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 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 the user to enter an alpha or numeric selection for a six-character
file name. The RIGHT/LEFT arrow keys select which character in the file name to edit and the
UP/DOWN arrow keys are used to choose a character. The chart below lists the available characters.
! " # $ % & ' ( ) * + , - x / 0 1 2 3 4 5 6 7 8 9 : ; < = > ? ] [ ¥ ^ _ @
A thru Z in uppercase
a thru z in lowercase
Pressing the ‘SAVE’key 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 keys and toggles ‘yes’ and ‘no’ with the UP and DOWN arrow
keys. 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 SDcard. Use the LEFT/RIGHT arrows to scroll through the parameters
and the UP/DOWN arrows to include or exclude parameters. Once finished creating the file name and
setting parameters, press the ENTER key. The file confirmation screen will appear. Press ENTER
again for confirmation to create the file, or press STOP to abort the process.

Transfer Data to a Computer
To view the collected data on a computer, the user can use the supplied USB cable and connect the
instrument to the USB host (computer). Alternatively, the user can remove the SDcard and view
files/data on the SDcard on another computer. Lastly, the user can wireless transfer files if it was
equipped with Wireless SD memory card (see below for further instructions). The ‘Dump’ command is
used to close the last file accessed before transfer. To do this, select ‘Open’ from the File Menu screen
and press the RIGHT arrow key. This will take the user to the View Files menu, and the last accessed
file will be highlighted. Press RIGHT arrow again and that file will be closed and ready for transfer.
Once the instrument data source is connected to the computer, it is strongly recommended that the
user copy and resave the files and images to the hard drive of the computer. The computer
application used to view the files can also be used to resave them. It is recommended that the user
does not work from the original file on the SDcard after the measurement has been made, because if
any changes are made to the original file, it can break the alignment of the file causing error and
possible data loss.
In order to keep the file system in sync, perform any editing or further calculations on the copied file
saved to the computer hard drive. Do not edit the file directly on the instrument.
Figure 6. SDcard and USB cable connection for CI-203
Do not connect the USB cable to the instrument and the computer while performing measurements. If
the user tries to operate the instrument through the computer, the files are subject to becoming out of
sync, breaking alignment and causing errors in the files. This can also lead to problems with saving
data.
If an error occurs in a specific data file, it can be deleted and created again. Go to the File Menu on the
instrument; clear the file where the error has occurred. If the file has been transferred to the
computer, delete it on the computer also. Once the corrupted files have been deleted, create the file
again (if it has been properly deleted, the same file name can be used) and re-take the measurement.

How Data Appears in a File
Data saved by the instrument during measurement can be viewed later on a computer using a
spreadsheet program. Fifteen different columns of data will be seen in the downloaded or transferred
file, including the date (month/day/year), time of measurement (hour/minute/second), area, length,
width, perimeter, ratio, factor, voids, latitude, longitude and altitude. Three columns are related to the
new GPS function of the instrument and the columns for file start location, length, and pixel lines for
the images (i.e. these columns do not relate directly to leaf measurements).

How to Work With or Manipulate Data Files
The CI-203’s removable SDcard makes it easy to work with and manipulate data files after taking
measurements. Remove the SDcard from the CI-203 after powering off the instrument. Insert the card
into a computer. Copy and save the files from the SDcard onto the hard drive of the computer. Open
the files saved on the hard drive to start any data manipulation or management work. Saving the data
files in this manner and not working directly from the SDcard will help to prevent the corruption of
the data on the SDcard and the instrument. Once files are copied and saved to a hard drive, they can
be deleted from the SDcard.
Do not edit files directly on the instrument. Doing so may corrupt data and cause loss of files.
