Appendix D: Probe Basics
This appendix contains basic information about the P3010 or P6139A probes
provided with your oscilloscope. It also contains information about other probes
you can use with your oscilloscope and their limitations.

Probe Compensation
You should compensate a probe to an oscilloscope input whenever you attach a
probe for the first time to any input channel. (See page 3, Probe Compensation.)
When compensating the P3010, only adjust the trimmer marked L.
