,
y
1
), (
x

), ...(
xn
,
yn
), and frequencies Freq1, Freq2, ... Freq

}
m
(DT)
only (without specifying the frequency).

After inputting sample data, you can press
c
to scroll through the data in the sequence
you input it. The
$
symbol indicates there is data below the sample that is currently on the
display. The
`
symbol indicates there is data above.
When the statistical frequency setting is FreqOn, data is displayed in the sequence:
x
1
,
y
1
,
Freq1,
x
2
,
y
2
, Freq2, and so on. In the case of FreqOff, it is displayed in the sequence:
x
1
,
y
1
,
x
2
,
y
2
,
x
3
,
y
3
, and so on. You can also use
