Vertical Scale (V/Div, V Range)
Voltage Scale Setting
The vertical scale is used to adjust the displayed waveform amplitude so that you can easily view signals. Set
the vertical scale for each main channel and each sub channel. On a 720254 4-CH module, select the sub
channel.
To change the vertical scale of a sub channel on the 720220 or 720221 16-CH module, select CH1 or CH3,
select the sub channel, and then set the vertical scale.
The vertical scale changes when you switch to an input attenuator with a different attenuation.
Scope Mode (V/Div)
Set the vertical scale by voltage per grid square (V/div) or current per grid square (A/div) on the screen. You can
change the scale in steps like this: 1 V/div -> 2 V/div -> 5 V/div.
Recorder Mode (V Range)
Set the vertical scale by specifying the voltage (V) or current (A) from the top edge to the bottom edge of the
waveform screen. You can change the scale in steps like this: 10 V -> 20 V -> 50 V.
Example
Scope Mode
1 div = 1 V
If 1 V/div is changed to 0.5 V/div,
1 div = 0.5 V

• While waveform acquisition is stopped, changing the vertical scale (V/Div, V Range) will not change the
displayed waveform. The changed V/div value will be applied the next time that waveform acquisition is
started.
• While waveform acquisition is stopped, changing the vertical scale (V/Div, V Range) will not change the
cursor-measurement values or the automated measurement values of waveform parameters, they will
continue to be based on the V/div value at the time of measurement.
