About the EA-200
The EA-200 is a digital device that makes it possible for you to sample data connected with everyday natural phenomena.
Data You Can Sample with the EA-200Various different sensors can be used with the EA-200 to sample temperatures, light, voltage, distance, and other data. The EA-200 supports sampling of up to 120,000 points, and simultaneous sampling over five channels. Sampled data can be sent to a compatible Graphic Scientific Calculator, where it can be viewed and graphed.
Before Using the EA-200 for the First Time
Power RequirementsYour EA-200 requires four AA-size alkaline batteries for power. Battery life depends on the amount of time the EA-200 is left on, and the amount of current used by the connected probe(s). A low battery indicator lamp (Batt) lights to let you know when it is time to replace batteries. To extend battery life, it is a good idea to use the AC adaptor for power whenever sampling indoors.
When using the EA-200 in combination with the optional “Motion Sensor (EA-2)”, be sure to power the EA-200 using its bundled AC adaptor (AD-A60024).
Though the EA-200 can normally operate on battery power, separate AC adaptor power is required while the optional “Motion Sensor (EA-2)” is being used.
Batteries are not loaded in the EA-200 when it is shipped from the factory. Because of this, use the following procedure to load batteries into the EA-200 before using it for the first time.
To load batteries
1. Remove the battery cover by pulling with your finger at the point marked 1. If there are batteries in the battery
