To change sampling unit
Press [Data Log] key continuously until desired unit is displayed. Note: The Data Analyser's Auto Power Off feature
is not active in this mode.
Data Analyser - Program Mode Equipment Set Up
Step 1: Connect the calculator to the Data Analyser using the cable. Press ends
in firmly. A definite "Click" sound is heard. Be sure to connect an Auto-ID probe to

Step 2: Switch the Data Analyser to Communications mode by pressing the
[MODE] key ("Done" appears on the screen)
Step 3: Turn the calculator on. Access the Program Mode of the calculator.
Select and execute the program you have written to be used with an activity.

Data Collection, Transfer and Analysis
"Ready" appears on the display.
Step 1: Press [Trigger] for the Data Analyser to begin collecting data.
Step 2: Depending on the activity, data can be collected "Real Time" or data can be collected then displayed on the
calculator graphically on completion of the data collection.
Step 3: "Done" appears on the Data Analyser display when data collection is complete.
Step 4: The program will normally contain instructions which automatically transfers the data to the calculator.
Step 5: A graph of the data will also be displayed and further mathematical analysis can be performed.
Using the EA-100 Data Logger with a probe
This activity looks at:
• use the data analyser to collect data on time and temperature.
• transfers data from the data analyser to the calculator.
• use the calculator to graph the relationship between time and temperature.
• use a mathematical model to model the collected data.
• Application of Newton's Law of Cooling.
Data Transfer to a Graphics Calculator.
Step 1: Connect the calculator to the Data Analyser
(Make sure that the plugs are in firmly.
Step 2: In RUN mode and using PRGM [SHIFT]
[VARS] .
Alternatively a 'short' program in the PRGM icon
from the MAIN MENU will do this data transfer from
the Data Logger to the calculator very quickly.
The example shown in this worksheet is to show how heat is lost from a hot cup of water when it is placed in a
room, free standing, to cool.
Two experiments are conducted, one with a simple cup of water and the second with a cup of water with a metal
spoon placed in the water to act as a "radiator" to compare and to see if there is any difference in the cooling rates.

[F4] for Receive. For List 1 etc [OPTN] [F1] & [F1] again.
List 1 is TIME and List 2 is the TEMPERATURE reading.
