results and may even fail to operate. Correct operation will resume once
the data analyzer unit is brought back to normal temperature.
• Replace the main batteries once every 2 years regardless of how much
the data analyzer unit is used during that period. Never leave dead batter-
ies in the battery compartment. They can leak and damage the unit.
• Keep batteries out of the reach of small children. If swallowed, consult
with a physician immediately.
• Avoid using volatile liquids such as thinner or benzine to clean the unit.
Wipe it with a soft, dry cloth, or with a cloth that has been dipped in a
solution of water and a neutral detergent and wrung out.
• In no event will the manufacturer and its suppliers be liable to you or any
other person for any damages, expenses, lost profits, lost savings or any
other damages arising out of loss of data arising out of malfunction, re-
pairs, or battery replacement. The user should prepare physical records
of data to protect against such data loss.
• Never dispose of batteries, the liquid crystal panel, or other components
by burning them.
• When the “Low batt.” message appears on the display, replace the batter-
ies as soon as possible.
• Be sure that the power is turned OFF when replacing batteries.
• Using the data analyzer unit near a television or radio can cause interfer-
ence with TV or radio reception.

CASIO Data Analyzer Overview
The CASIO Data Analyzer is a digital instrument you can use to sample and
collect data on various everyday natural phenomena. The following sections
provide information on using its probes and channels, and tell you how to
connect to a graphic scientific calculator. A number of other important func-
tions of the data analyzer unit are also introduced here.
Sample Data
The probes that come with the CASIO Data Analyzer make it possible to
sample temperature, light, and voltage. Data sampling can be performed at
up to 512 points per channel, and data can be sampled on up to five chan-
nels simultaneously. Data can be transferred to a CASIO CFX-9850G or CFX-
9800G graphic scientific calculator as it is sampled.
Probes
Probes are actually sensors for picking up data on temperature, light, and
other natural phenomena.
When using the supplied probes, the data analyzer unit’s Auto-ID feature
automatically detects which of the probes is connected.
Channels
Probes are connected to input/output terminals, called “channels,” that are
equipped on the data analyzer unit. There are a total of six channels for
connection of probes: three analog channels (CH1, CH2, CH3), one ultra-
sonic channel (SONIC), one digital input channel (DIG IN), and one digital
output channel (DIG OUT).
Data Analyzer and the CFX-9850G/CFX-9800G
Though the data analyzer unit can be used alone to sample, store, and recall
data, you can also connect to a graphic scientific calculator for more detailed
manipulation and analysis of sampled data. The data analyzer unit can be
controlled from the calculator, and sampled data can be displayed in graphic
form on the calculator’s screen.
Control of the data analyzer unit is performed by sending calculator list data
(CFX-9850G) or matrix data (CFX-9800G), which the data analyzer unit in-
terprets as commands.
The data analyzer unit can be linked to a CFX-9850G or CFX-9800G graphic
scientific calculator by connecting the input/output terminals equipped on each
unit with a data communication cable (SB-62).

Chapter 1: Getting Ready
Command and Programs
There are a total of 10 commands defined for this data analyzer unit: Com-
mand 0 through Command 9. These commands can be used to specify such
parameters as the type of data being sampled, the channel being used for
sampling, the sample time, and the number of samples. Commands are sent
from a connected graphic scientific calculator (CFX-9850G/CFX-9800G) to
the data analyzer unit, which then executes them.
A program is a set of multiple commands that cause the data analyzer unit to
perform a series of actions. For example, you could send a set of commands
that tell the data analyzer unit to set up, to sample some data, and then send
the data back to the calculator. Data analyzer unit programs can be written
using the CFX-9850G graphic scientific calculator’s program function only.
Be sure to read the documentation that comes with the CFX-9850G to thor-
oughly familiarize yourself with the programming function before trying to use
it to control this data analyzer unit.
Conversion Equations and Post-processing
Conversion Equations
The physical units measured by the probes are converted into a more easily
understood unit of measurement by built-in conversion equations. In the case
of the temperature probe, for example, changes in temperature are meas-
ured by fluctuations in electrical resistance by an electrical device called a
“thermistor.” The conversion equation converts the measured resistance value
to a temperature unit (such as degrees Celsius) and produces the converted
value on its screen. Each of the analog channels and the SONIC channel
has its own built-in conversion equation.
Post-processing
The data analyzer unit provides the means to perform certain calculations
using sampled data when required. This is called “post-processing” (process-
ing of data after it is sampled).
This data analyzer unit supports three types of post-processing: first deriva-
tive, first and second derivatives, and statistics. Selecting first and second
derivatives for post processing, for example, calculates the first and second
derivatives* for the sample data and stores the result into memory. Selecting
statistics calculates the mean, standard deviation, minimum and maximum
for the sampled data and stores them in memory. Calculated data can also
be downloaded to a graphic scientific calculator.
* The term “derivative” here means “time increment.”

Chapter 1: Getting Ready
Data Filtering
Static “noise” can sometimes cause sampled data to become corrupted,
making it impossible to obtain accurate results from calculations and analy-
sis. This data analyzer unit includes a data filtering system that eliminates
noise and help to make sure that data is always accurate.
Keyboard
The front panel of this data analyzer unit has a liquid crystal display screen
and eight keys.

Reading the Display
The data analyzer’s liquid crystal display (LCD) is divided among five areas,
each of which indicates the status of a particular operation.
Display Panel
The display screen shows the current operating mode, the input/output chan-
nel being used, and information about the current sampling operation.
Area 1
A r e a 3 A r e a 4 A r e a 5
Area 2
Display Screen Areas
Area 1 (Channel Area)
This area shows the active channel and the sampling unit for each channel,
and whether recorded time data is absolute or relative. Channel indicators
(CH1, CH2, CH3, SONIC, DIG IN, and DIG OUT) appear to indicate the
currently active channel. The sampling units to the right of each channel indi-
cator show the sampling unit for the probe connected to the channel. An EQ
indicator (EQ1 through EQ4) also appears when a conversion equation is
being used. The RecTIME indicator appears when time data is being re-
corded along with sampled data. “Abs.” indicates absolute time, while “Rel.”
indicates relative time.
Area 2 (Post-processing Area)
The indicators in this area (d/dt, d2/dt2, STAT ) show what type of post-process-
ing of data is being performed. SHIFT appears to indicate that the keyboard
is shifted and that the functions marked above the [MODE], [INTERNAL] and
[HALT] keys are enabled.

Chapter 1: Getting Ready
Area 3 (Sampling Status Area)
The indicators in this area shows the current data sampling status. READY
means the data analyzer is ready and standing by for data sampling, SAM-
PLING indicates that a sampling operation is in progress, and DONE means
that the sampling operation is finished. All three of these indicators flash in
the Setup Mode.
Area 4 (Mode Area)
These indicators show the current operating mode of the data analyzer. The
DATA-LOG, INTERNAL, or MULTIMETER indicator appears when the corre-
sponding mode is entered. No indicator is shown when the data analyzer is
in the Communications Mode.
Area 5 (Data/Output Unit Area)
This area shows the sampled data values and error codes. The indicators on
the right include unit (meters, ", seconds, etc.) indicators and a low battery
indicator.
• Keep in mind that Area 1 shows the unit used by the probe for sampling,
while Area 5 shows the unit used for displayed or output values, so the
two areas may indicate two different units. When the temperature probe
is used, for example, Area 1 will indicate Ohms (") as the unit because
the probe uses a thermistor to measure temperature as a change in
resistance. Area 5, on the other hand, will indicate°F or °C, because this
is the unit used to represent the displayed value.
Out-of-Range Samples
Samples that exceed the allowable range for a particular probe are indicated
on the display as shown below. This sample display shows the out-of-range
message for temperature measurements.
• Voltage: Greater than 10V
• Temperature: Greater than 130°C
• Light: Greater than 999

10
Chapter 1: Getting Ready
• Voltage: Less than –10V
• Temperature: Less than –20°C
• Light: Less than 100
Power Supply
The data analyzer can be powered by four AA-size batteries or an optional
AC adaptor (AD-A60024). This section tells you when you should replace
batteries and how to connect the optional AC adaptor.
Batteries
The data analyzer can be powered by four AA-size batteries. Battery life
depends on how long you leave the data analyzer turned on, and the amount
of current required by the probes you use. A low battery message appears
on the display whenever battery power drops below a certain level.
Note that you can extend battery life by using the optional AC adaptor (AD-
A60024) whenever possible.
To load batteries
1. Holding the data analyzer unit upright, press down on the {!OPEN} part
of the battery compartment cover and slide the cover off.
If you are replacing batteries, remove all four old batteries from the com-
partment.

11
Chapter 1: Getting Ready
2. Load four AA-size batteries into the battery compartment, making sure
they are facing as shown in the illustration inside the battery compart-
ment.
3. After loading batteries, replace the battery compartment cover.
4. Press [ON/OFF] to turn on power, which should make the screen shown
below appear on the display.
Battery Replacement Interval
You should replace all four batteries at least once every 2 years to avoid
problems caused by battery fluid leakage, even if the low battery messages
does not appear during that time. Should the low battery message appear,
replace the batteries with a full set of new ones as soon as possible. Failure
to do so can result in errors by the data analyzer.
• Be sure to switch to optional AC adaptor power or back up sampled data
by transferring it to a graphic scientific calculator before removing the
batteries from the data analyzer. Removing batteries while the data
analyzer is not being supplied power through the optional AC adaptor
results in all sampled data and operational settings to be lost. Use of the
optional AC adaptor is always recommended to ensure data security
and stable data analyzer operation.
Auto Power Off
The Auto Power Off function conserves battery power by normally turning
power off if no key operation is performed for about 10 minutes. Auto Power
Off is disabled (it does not turn power off) in the Multimeter Mode, in the
READY state, and in the SAMPLING state.
Optional AC Adaptor
Caution!
• Never connect to an outlet that supplies current that is different from that
marked on the AC adaptor, and do not connect the AC adaptor to an
extension cord shared by other devices. Either of the above creates the
danger of fire and electrical shock.

12
Chapter 1: Getting Ready
• Never try to modify the power cord of the AC adaptor, do not allow it to
become broken or cracked, and do not subject it to excessive bending,
twisting, or pulling. Do not place heavy objects on top of the power cord
and do not subject it to direct heat. Any of the above creates the danger of
fire and electrical shock.
• Never touch the AC adaptor while your hands are wet. Doing so creates
the danger of electrical shock.
Important!
• Never pull on the power cord when unplugging the AC adaptor from a wall
outlet. Doing so creates the danger of damage to the cord, fire, and elec-
trical shock. When unplugging the AC adaptor, be sure to grasp the body
of the adaptor.
• Be sure to unplug the AC adaptor from the wall outlet whenever leaving it
unattended for long periods.
• Be sure to use only a genuine optional AD-A60024 AC adaptor. Use of
another type of adaptor can result in damage to the adaptor, the data
analyzer, or some other unforeseen serious problem. Use of an unau-
thorized AC adaptor also voids your warranty.
• Remove the batteries from the data analyzer whenever you plan to oper-
ate under AC adaptor power for long periods.
• Be sure to turn the data analyzer off before connecting the AC adaptor.
• The body of the AC adaptor becomes warm to the touch when used for
long periods. This is normal and does not indicate malfunction.
To connect the AC adaptor to the data analyzer
1. Press [ON/OFF] to turn power off.
2. Connect the AC adaptor’s plug into the AC adaptor terminal on the bottom
of the data analyzer.
3. Plug the other end of the AC adaptor’s power cord directly into a wall
outlet.
4. Press [ON/OFF] to turn on power.

Chapter 1: Getting Ready
Connecting the Data Analyzer to a
Calculator
The following procedure describes how to use the data communication cable
that comes with the data analyzer to connect it to a CFX-9850G or CFX-
9800G graphic scientific calculator.
1. Turn both units off.
2. Plug one end of the data communication cable into the data communica-
tion terminal of the calculator you are connecting to.
3. Plug the other end of the cable into the data analyzer’s data communica-
tion terminal.
• When connecting the data communication cable, be sure to push it se-
curely into the terminal as far as it will go. Poor cable connection is the
first thing you should check whenever you experience data communica-
tion problems.
• Be sure to read the chapter describing data communication in the docu-
mentation that comes with the calculator you are connecting to.
Connecting a Probe
Connecting probes to the various input channels provides the means to sam-
ple various types of data, including temperature, light, distance, voltage, etc.
About Input Channels
You can connect more than one probe and sample different types of data
simultaneously. Indicators in Area 1 of the display tell you which channel is
currently active.
There are three channel types: analog, digital, and ultrasonic, and the con-
nector of each type is slightly different to protect against plugging in the wrong
type of probe.
