Hioki 8847 - Magnifying and Compressing Waveforms; Magnifying and Compressing Horizontal Axis (Time Axis)

7.5 Magnifying and Compressing Waveforms
110
This applies to the Memory function and Recorder function. (However, with the Recorder
function, waveform magnification is not available.)
Data details can be observed by magnifying the waveform along the horizontal axis (time axis).
Also, by compressing the time axis, overall waveform fluctuations can be readily seen.
On-screen magnification and compression is based on the left edge of the screen. However, when
A/B cursor appears on the screen, use the cursor as the standard to expand or compress.
The amount of magnification/compression can be changed after measurement.

When [Zoom On] is selected, a section of the time axis will be mag-
nified.

To print at a different zoom ratio from the display
Specify the ratio on the [Printer] sheet.
See: "Set the horizontal axis (time axis) magnification and compression." ( p.96)
When a waveform loaded from media is displayed at a high compression
ratio, the display may be slow to update.
