NOTE
If the magnification or compression ratio is changed when the
zero position is not at 50% for the Memory Recorder and
Recorder, or not at 0% for RMS, the zero position of the
waveform will be changed.
The actual measurable range for each voltage range is about
1.2 times full scale of the voltage axis. The display area on the
Waveform Screen depends on the magnification and
compression ratio setting, but the measurable range is not
affected. Therefore, even though an area that is outside of the
measurable range may be displayed on the screen, those parts of
a waveform that are out of range cannot display.
For example, if a compression ratio of
x1/2 is set with the zero position to 0%
in the 10 mV range, the screen height will
show an area that is twice the full scale
range, equivalent to 0 to 200 mV,
although the measurable range of
waveforms that can be input is limited to
about
1.2 times full scale range (-120 to
120 mV).

7.3.5 Setting the Magnification/Compression
Ratio Along the Voltage Axis
The voltage axis can be independently magnified or
compressed for display and recording of each channel.
Magnification and compression are applied relative to the
center of the display (50%).
Procedure
Channel Screen
1. Press the
SET
button to display the Channel Screen.
2. Move the flashing cursor to the desired channel position.
3. Use the
buttons to make a setting.
