3. Probe Attenuation Setting
The oscilloscope allows selecting the attenuation factor for the probe. The
attenuation factor changes the vertical scaling of the oscilloscope so that the
measurement results reflect the actual voltage levels at the probe tip.
To change (or check) the probe attenuation setting, press the CH1 or CH2 button
(according to which channel in using). Toggle the Probe soft button to match the
attenuation factor of the probe.
This setting remains in effect until changed again.
Figure 2-8 show an example for using a 1000:1 probe and its attenuation factor.
