Key Operation Description
K4(CALC)
Displays a menu that lets you transform a sample result graph to a 
function using Fourier series expansion, and to perform regression 
to determine the tendency of a graph. See “Using Fourier Series 
Expansion to Transform a Waveform to a Function” on page 11-6, and 
“Performing Regression” on page 11-8. 
K5(Y=fx)
Displays the graph function list, which lets you select a Y=f(x) graph to 
overlay on the sampled result graph. See “Overlaying a Y=f(x) Graph 
on a Sampled Result Graph” on page 11-9.
K6(SPKR)
Starts an operation for outputting a specific range of a sound data 
waveform graph from the speaker (EA-200 only). See “Outputting a 
Specific Range of a Graph from the Speaker” on page 11-12.
k Scrolling the Graph Screen
Press the cursor keys while the graph screen is on the display scrolls the graph left, right, up, 
or down. 
Note
• The cursor keys perform different operations besides scrolling while a trace or graph 
operation is in progress. To perform a graph screen scroll operation in this case, press 
 J to cancel the trace or graph operation, and then press the cursor keys.
