For certain active probes, such as InfiniiMax probes, the oscilloscope can
accurately calibrate its analog channels for the probe. When you connect a
probe that can be calibrated, the Calibrate Probe softkey in the Channel
Probe Menu becomes active.
To calibrate one of these probes:
1 First, plug your probe into one of the oscilloscope channels.
2 Connect the probe to the left side, Demo 2, Probe Comp terminal, and

and the negative lead to the ground terminal. You may need to connect an alligator clip to
the ground lug to allow a differential probe to span between the Probe Comp test point and
ground. A good ground connection ensures the most accurate probe calibration.
