Chapter 1: Getting Ready 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 functions of the data analyzer unit are also introduced here.
Chapter 1: Getting Ready Command and Programs There are a total of 10 commands defined for this data analyzer unit: Command 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.
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 analysis. 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.
Chapter 1: Getting Ready Key Functions The following describes the functions of each of the eight keys on the keyboard. This section is intended more as a reference and contains information that may be difficult to understand at first glance. Don’t worry though, many of the expressions used in the following key function descriptions will become clearer after you read the section of this manual titled “Modes.
Chapter 1: Getting Ready Key Description • Data-Log Mode: Each press of [CH-View] in this mode sequentially switches the channel whose data is on the display. The channel indicator of the currently selected channel flashes on the screen. [INTERNAL] Pressing this key while in the Communications Mode enters the Internal Mode. Pressing it again returns to the Communications Mode P.35 [XMIT-9800] Pressing [SHIFT][INTERNAL] sends data to the CFX-9800G.
Chapter 1: Getting Ready 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 channel being used, and information about the current sampling operation.
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, SAMPLING 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.

All three analog channels perform identical types of sampling. Ultrasonic Input Channel This channel is for connection of a distance sensor that can be used to measure the distance from the probe to an object.
Chapter 3: Commands and Programming Chapter 3: Commands and Programming This chapter describes how to set up the data analyzer and control it using commands sent from a connected CFX-9850G or CFX-9800G graphic scientific calculator. Command Conventions and Formats ................................ 24 Programming ..................................................................... 26 Sending Commands from a Calculator to the Data Analyzer ....................................................
Chapter 3: Commands and Programming Command Conventions and Formats Commands sent from a connected CFX-9850G or CFX-9800G graphic scientific calculator can be used to make various settings and control operations of the data analyzer. Commands Commands can be written as CFX-9850G list data or CFX-9800G matrix data in the format shown below. {m,n,n,n,n,...} Command number Parameter number There are a total of 10 commands numbered from 0 through 9. The following describes the function of each command.
Chapter 3: Commands and Programming Number 6 Description MULTIMETER MODE SETUP This command sets the Multimeter Mode unit of measurement for a particular channel. 7 REQUEST STATUS This command creates a data list concerning the data analyzer’s current status (error status, probe connection data, etc.) being requested by the connected calculator. 8 SAMPLING START This command causes the data analyzer to start sampling immediately.
Chapter 3: Commands and Programming Programming Programs can be input on the CFX-9850G graphic scientific calculator and then sent to the data analyzer to make it perform a series of tasks. • Note that data analyzer control programs can be input on the CFX-9850G graphic scientific calculator only. The CFX-9800G can be used to send commands one-by-one. Tasks Normally Controlled by Programs The following outline describes the normal sequence of a data analyzer system control program. 1.
Chapter 3: Commands and Programming Example Program The following is an example program written for the CFX-9850G. Cls ! CFX-9850G graph clear operation {1,0} " List 6 ! Send(List 6) ! Clears all channel settings and data. {1,1,1} " List 6 ! Send(List 6) ! Specifies sampling with Auto-ID probe connected to CH1. {3,0.5,100,1} " List 6 ! Send(List 6) ^ Specifies sample time of 0.5 seconds, 100 samples, and absolute time recording on.
Chapter 3: Commands and Programming the list. When using the Send(List) command, you should specify the list that contains the commands by replacing “List” with a CFX-9850G List variable (List 1 through List 6). • Sending a new setup command (Command 1 or Command 3) clears all previously sampled data from data analyzer memory. To input the “Send(” command on the CFX-9850G 1.
Chapter 3: Commands and Programming 7. Repeat steps 5 and 6 as many times as necessary to send any other matrix data that you want. Matrix Data Example The following describes a typical example procedure for sending commands that set up the data analyzer for sampling of distance data with a distance sensor. 1. Input the following matrix data on the CFX-9800G. 1 0 Channel clear 1 Command 1 4 Channel: SONIC 2 Unit: meters 3 Command 3 0.5 Sampling duration: 0.
Chapter 3: Commands and Programming Transferring Sampled Data to a Calculator This section explains how to send sampled data between the data analyzer and a connected CFX-9850G or CFX-9800G graphic scientific calculator for graphing and analysis. Transferring Data to the CFX-9850G The following explanations all apply to transferring data from the data analyzer to the CFX-9850G only. To use the “Receive(” command to fetch data 1. Connect the data analyzer to the CFX-9850G. 2.
Chapter 3: Commands and Programming P.34 • Note that the data transferred by a Receive(List) command execution is somewhat different when statistical post-processed data is involved. See “Using Receive(List) to Fetch Statistical Post-Processed Data”. The following are detailed explanations of how the Receive( command works with each type of parameter that can be specified with it. Receive(Variable) This format assigns received data to a variable.
Chapter 3: Commands and Programming Sample Operation Using Receive(List) The following program fetches sampled data items and assigns them to CFX9850G list variables. Receive(List 1) Fetches up to 255 data items from the lowest numbered channel*, and stores them in List 1. Receive(List 2) Fetches up to 255 data items starting from the next active channel, and stores them in List 2.
Chapter 3: Commands and Programming with the first derivative calculated for CH1 sample data, and the second derivative calculated for the SONIC channel. P.52 P.37 P.52 DATA RANGE SETUP parameters (Command 5) can be used to specify the data groups and data range to be transferred to the CFX-9850G. This command comes in handy when you want to fetch only specific data items, or when there are more than 255 data items in data analyzer memory.
Chapter 3: Commands and Programming Two Receive(List) cycles are required in this example because there are more than 255 samples. Following the first two Receive(List) commands, a single Send(List) is necessary to verify the data fetches from the SONIC channel. The next Send(List) command specifies the data range of Receive(List4) and Receive(List5). The following shows how data is stored in the different lists after execution of this program is complete. List 1 .... CH1 data samples (1 to 255) List 4 ....
Chapter 3: Commands and Programming Using Receive( to Fetch Time Data P.45 Either relative or absolute time data recording can be specified with the time recording parameter of the SAMPLE AND TRIGGER SETUP (Command 3). Specifying 1 (absolute time on) or 2 (relative time on) records time data in seconds whenever data is being sampled. Let’s say, for example that we want to sample temperature data with only CH1 is active, and the time recording parameter set to 1 (absolute time on).

Chapter 2: Modes Chapter 2: Modes This chapter provides detailed explanations of the Communications Mode, Multimeter Mode, Internal Mode, Data-Log Mode, and Setup Mode. Relationships Between Modes ........................................... 16 Communications Mode ...................................................... 17 Multimeter Mode ................................................................ 17 Internal Mode ..................................................................... 18 Data-Log Mode ....
Chapter 2: Modes Relationships Between Modes The data analyzer has five modes: Communications, Setup, Multimeter, Internal, and Data-Log. The operations in the Communications, Setup, and Multimeter modes are closely interrelated. The are the three basic configurations under which the data analyzer can be used.
Chapter 2: Modes Communications Mode The purpose of the Communications Mode is data sampling. While in this mode, the data analyzer receives setup commands from a connected calculator, performs sampling, and then sends the sample data to the calculator. This mode has three data analyzer states: READY, SAMPLING, DONE. READY The data analyzer enters the READY state (indicated by the READY indicator on its display) when a setup command (Command 3) is received from the calculator.
Chapter 2: Modes To enter the Multimeter Mode, press the [MODE] key while in the Communications Mode. Press [MODE] again to return to the Communications Mode. The data analyzer is in the Multimeter Mode when the MULTIMETER indicator is on the display. To perform Multimeter Mode measurements using the SONIC channel, for example, press [MODE] to enter the Multimeter Mode and then press [CHview] three times to select the SONIC channel. Measurement results appear on the display of the data analyzer.
Chapter 2: Modes Data-Log Mode This mode is for displaying data stored in data analyzer memory. Pressing [DataLOG] while in the Communications Mode enters the Data-Log Mode, which is indicated by the DATA-LOG indicator on the display. When you enter the Data-Log Mode, the channel indicator of the first channel for which there is data in memory starts to flash, and the first data item for that channel appears on the display.
Chapter 2: Modes Setup Mode P.21 This mode lets you set up the data analyzer manually without an external program for simple sampling jobs using an Auto-ID probe. In the Communications Mode, press [SHIFT] [MODE] to enter the Setup Mode, which is indicated by the READY, SAMPLING, and DONE indicators all flashing on the display.
Chapter 2: Modes displays the “Rel.” indicator. 7. When the setting you want to use is displayed, press [TRIGGER] to register it and return to the Communications Mode. • At this time confirm that an Auto-ID probe is connected and make sure that the READY indicator is on the display of the data analyzer, indicating it is in the READY state.*3 *1 If the setting is greater than 999, it is automatically changed to 999.
Appendix A: Technical Reference Appendix A: Technical Reference This appendix provides information on the error messages that appear on the display of the data analyzer, information about probes that come with the data analyzer, conversion equations, and other technical information. Error Messages .................................................................. 62 Probes ................................................................................ 62 Conversion Equations ..............................
Appendix A: Technical Reference Error Messages The data analyzer indicates an error by displaying “E.” followed by a 2-digit hexadecimal number. The first digit indicates the command that caused the error, while the second digit indicates the parameter that caused the error message (first parameter indicated by 1, second parameter by 2, and so on). Sample Error Message E.13 E. ... Error message 1 ..... Error in Command 1 3 ..... Error in third parameter.
Appendix A: Technical Reference Temperature Probe The temperature probe that comes with the data analyzer uses a thermistor to measure the temperature of liquids. Changes in the temperature of the thermistor causes a corresponding change in its resistance, which is then converted to a temperature value.
Appendix A: Technical Reference Probe Precautions Temperature Probe • Never use the temperature probe with strong acid or alkaline solutions. • The measuring range of the temperature probe is –20°C to 130°C. Do not try to measure temperatures outside this range. • Do not use the temperature probe for longer than two hours of continuous measurement when measuring temperatures greater than 80°C.

Appendix A: Technical Reference Conversion Equations Command 4 Type, Form, and Restrictions Command 4 conversion equations have certain calculation limitations. In particular, some conversion equations cannot perform calculations for negative values. If a division by zero, power of a negative number, or other such error is encountered by an equation, an overflow value is automatically applied to the operation.
Appendix A: Technical Reference Other Technical Information Clock-In Line Operation A low-going pulse (0-5V) on the External Clock-In line (part of the DIG IN channel) is used as the external clock. Data from the DIG IN channel can be read based on the internal sampling clock, so the External Clock-In line is not necessarily required. Conversely, the external clock line can be used to control the sampling time for signals on other channels.
Appendix A: Technical Reference Command 3: {3,1,70} 3 = SAMPLING AND TRIGGER SETUP 1 = Sampling time (1 second) 70 = Number of samples The manual trigger default is applied as the trigger source. The DOB outputs signals that correspond to the seven data nibbles. This sequences is repeated to the DIG OUT channel 10 times (70 samples/7 data elements). The following diagram shows the output for the first seven data elements.
