Offset Cancel (Offset Cancel)
You can set whether or not to apply the specified offset to various measured values.
The offset-cancel feature ON/OFF setting applies to all channels. The default setting is off.
• ON
The specified offset is applied to the result of cursor measurements, computations, and automated
measurement of waveform parameters. The offset is subtracted from the input signal, and various
measurements are performed. The vertical position is set to zero.
• OFF
The specified offset is not applied to the result of cursor measurements, computations, and automated
measurement of waveform parameters. The offset is not subtracted from the input signal, and various
measurements are performed. The vertical position on the screen corresponds to the offset.

• The offset setting applies to all input coupling settings (AC, DC, DC50).
• If you change the probe attenuation, the vertical scale settings change the values that have been scaled
with the new attenuation ratio.
• The offset value does not change even if you change the vertical scale. However, if the offset value goes
outside the selectable range, the offset is set to the maximum or minimum value in the vertical scale range.
If you do not change the offset and set the vertical scale back to its original value, the offset returns to its
original value.
