Zoom Position (Z1Position and Z2Position)
• The zoom position can be set by specifying the zoom center position (center of the
zoom box) in the range of –5 to +5 divisions with the center of the waveform display
area set to 0 division. The resolution is as follows:
Selectable steps of zoom position: Record time

÷
display record length
• The zoom box enclosed by solid lines is Z1, and the one enclosed by dashed lines is
Z2. Since each box is independent, you can set the position separately.
Changing the Range of the Automated Measurement of Waveform
Parameters (Fit Meas Range to Z1/Fit Meas Range to Z2)
Set the range of the automated measurement of waveform parameters to the zoom
range of Z1 or Z2. This setting is effective even when the automated measurement of
waveform parameters is turned OFF.
Moving the Zoom Box to the Most Recent Position of the Waveform (Z1 to
Front/Z2 to Front)
Moves the zoom box of Z1 or Z2 to the most recent position (right end) of the main
waveform.
Auto Scroll
The zoom box automatically moves (scrolls) in the specified direction. You can scroll
while viewing the expanded waveform.
Scroll Direction
Set the scroll direction to << (left) or >> (right).
Display Position of the Search Result Window
When the zoom mode is Main&Z1&Z2 or Z1&Z2, you can select the window, Z1 or Z2,
that will display the searched waveform.
Scroll Speed
Set the scroll speed using 10 levels from 1 to 10. The speed increases as the number
gets larger.
Note
•
Auto scroll is not possible while the data acquisition is in progress.
•
You can only change the Direction and Speed while auto scroll is in progress.
