Extrapolating Template Data
In cases where the display scale is outside the defined range for template data, the
template data outside the range can be extrapolated.
The following three types of extrapolation are available in these situations.
• Type A Extends the outermost data point of the template data to the outside.
• Type B Extends, to the outside, a line joining the outermost template data and the
adjacent data point.
• None No extrapolation.

Note
• Data created through extrapolation is limited by the LOG LIMIT setting.
• For templates set to None, the Go/No Go judgment range from the template can be
narrower than the waveform display screen. Pay attention to the judgment execution ranges
for the upper limit and lower limit lines.
