Waveform data consists of 100 samples per division.
With the Recorder function, each data sample consists of the maximum and min-
imum values acquired in the specified sampling period. So each data sample
has its own amplitude breadth.
When input waveform variation is slight, the difference between maximum and
minimum values (breadth, or width) can be inordinately large if the sampling
period is short and if severe fluctuations are present due to noise.
This phenomena may be prevented by setting a longer sampling period.

The ranges of the values enclosed in curly brackets { } are as follows:
-9.9999E+9

Value enclosed in { }

-1.0000E-9
-9.9999E+9

Value enclosed in { } = 0
+1.0000E-9

Value enclosed in { }

+9.9999E+9
A warning appears if a setting is outside of the above ranges, and the set value
after conversion = the voltage value. (Y = X)
On channels for which waveform processing calculations have been recorded,
converted measurement units are applicable only to the calculation results.
(Scaling is otherwise disabled)
Scaled valued are displayed on the gauge scale, on-screen upper and lower limit
values, and cursor values when using A/B cursors.
