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. 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 channels 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 ultrasonic 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 interprets 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). 3 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. 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 thoroughly 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 measured 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 scre...
