When the displayed waveform is not centered correctly (for example, due to a
small DC offset error), you might need to press the AutoZero button in the Probe
Setup menu of the oscilloscope. This might be necessary for the first time after
the self calibration operation has completed. Make sure there is no differential
signal present at the sensor tip cable.
Press the MENU button on the controller to view the Probe Setup menu on the
oscilloscope, similar to the following figure.

clamping on or off, or setting the input ranges.
