Changing the Interpolation Settings

Press the

DISPLAY key

to display the setting menu.

Press the “

Intrpl

” soft key to display the interpolation selection menu.

Press the soft key corresponding to the desired interpolation type.

Explanation

Selecting the interpolation type: Intrpl

The following four interpolation types are available. The default is “SINE”.

OFF

No interpolation; Displays the sampling data as a horizontal line.

LINE

Interpolates between two dots with a straight line.

SINE

Generates interpolation data using a sine function and interpolates between two
dots using a sine curve.

PULSE

Draws a horizontal line to a point directly above or below the next data point and
then interpolates using two dots so that the end of the horizontal line is connected
to the next data point by a vertical line.

Note

LINE, SINE and PULSE can only be selected if the number of display points per division is 50 or less.
OFF can always be selected.
