Channel
Select the channel for the offset compensation.
AutoZero, Use AutoZero
Differences in DUT and oscilloscope ground levels can cause larger zero errors, which
affect the waveform. If the DUT is ground-referenced, the AutoZero function corrects
the zero error of the probe to optimize measurement results at small signal levels. The
validation limit depends on the probe attenuation because probes with high attenuation
often have to compensate high offsets. AutoZero detects offset values even when the
signal is out of the current measurement range.
To correct the zero error of voltage probes, short the signal pin and the ground pin
together and connect them to the ground of the DUT. Then tap "AutoZero". While the
alignment is running, the instrument switches to DC coupling to display the waveform
correctly.
To include the measured offset in measurement results, enable "Use AutoZero".
If a current probe is connected, the function demagnetizes the probe's sensor head
and sets the waveform to zero position.
