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.

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. 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.
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.
t = 76 w = 0

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.
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.
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 keys at the same time.
2. Hold the buttons until the motor begins to spin. The motor should spin for about 4
seconds.
3. Do this twice by pressing the LEFT and RIGHT arrow keys 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 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.

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.
Note: 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

Format Storage
Pressing the UP/DOWN key switches the display to the “format storage” mode screen. Be
careful! 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 the 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.
Clear all data
<stop> <enter>
To delete every file in your instrument, press the ENTER key. The instrument will erase ALL
data from the memory, leaving the maximum possible amount of memory free for use. To stop
the deleting process and exit Setup ‘Storage’ menu, press the STOP key. To continue
measurements, the user must create a blank file.
Setup Time and Date
To change the time and date stamp on the CI-203, press the RIGHT key when ‘Time’ is
highlighted on the Setup Scanner menu. This utility allows the user to set-up the instrument in
different time zones or to adjust the time after daylight savings.
To change the time on the instrument, use the UP/DOWN arrows to change the values of the
first row (hour: minute: second). Use the LEFT/RIGHT arrow to highlight the appropriate
column, make the appropriate shift in time and press SAVE. To change the date and access
the second row, press the LEFT and RIGHT arrow keys simultaneously. The second row

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.
