Step 6. Compensate probes
Compensate probes to match your probe to the input channel. You should
compensate a probe whenever you attach it for the first time to any input
channel.
Low Frequency Compensation
For the supplied passive probes:
1 Set the Probe menu attenuation to 10X. If you use the probe hooktip,
ensure a proper connection by firmly inserting the tip onto the probe.
2 Attach the probe tip to the probe compensation connector and the
ground lead to the probe compensator ground connector.
3 Press the [Auto Scale] front panel key.
4 If waveform does not appear like the Correctly Compensated waveform
shown in Figure 4, then use a nonmetallic tool to adjust the low
frequency compensation adjustment on the probe for the flattest square
wave possible.
