lists the time relative to the instantaneous change from the last setting. Don’t

worry if that doesn’t mean anything to you, since you won’t be using it

anyway. When you see 1, press [TRIGGER] to enter the choice.

 Once you have entered your choice for sample rate, number of samples, and

time definition, you are ready to begin collecting data. “READY” will show

on the left side of the screen. By pressing [TRIGGER] again you will begin

sampling data. You can tell that the EA100 is receiving data because it will

blink “SAMPLING” on the left side of the screen. [HALT] will allow you to

stop the sampling and [SHIFT] [HALT] which activates [RESTART] will

allow you to initialize or re-setup to the last chosen sample rate and time.

 When all samples have been collected DONE will appear on the left side of

the screen.

 Pressing [DataLOG] will toggle you through each of the data samples.

Pressing [CH-View] will switch you between channels if you have more than

one probe connected to the EA100.

Transferring Data

The EA100 is essentially a data collection device. It must be used in

conjunction with a graphing calculator or computer in order to analyze or interpret the

collected data. You will use the “Receive” command on the graphing calculator to bring

data from the EA100 into the calculator. Once you have transferred the data, then you can

graph it and display it for analysis and interpretation.

 Make sure that BOTH the EA100 and the FX2.0 are turned OFF. This is

important because the calculator only searches for attached devices when it is

initially turned on. With both devices turned OFF, connect the EA100 to the

FX2.0 using the black data transfer cord which has two identical ends, each

with a gold insertion probe about 2 cm long. It is this gold insertion probe that

you insert into the end of the EA100 and the FX2.0. Be sure that the cord is

plugged in securely and that it “snaps” into place. The most common error for

failure to transfer data is a poor connection of the cord to one or both of the

devices. You will not loose your data you have just collected if you turn off

the EA100 to connect to the calculator.

 Once you have connected the EA100 and the FX2.0, you need to turn both of

them ON. Recall that the EA100 starts off in communications mode, which is

the mode you need to be in if you want to transfer data to a calculator.

 You will need to tell the calculator to receive the data. On the FX2.0, you

need to be in the RUN-MAT menu. So press [MENU] then choose [1]. Press

[SHIFT] [VARS] and a menu will appear at the bottom of the screen and the

choice above [F5] will be I/O for input/output. Press [F5]. A small window

will pop up on the left side of the screen and you want to “Receive” data, so

press [4]. Showing on the FX2.0 screen will be Receive( , with the cursor

blinking behind the opened parenthesis.

 The Data Logger collects two different sets of data. The first set is the set of

times for which the probe collected data. The second set is the information

collected by the probe. The EA100 automatically sends the time data first and

the probe-collected data second. To receive the time data you must indicate a
