probe for the first time to any input channel. A poorly
compensated probe can introduce measurement errors.
1. Set both the probe and the oscilloscope attenuation
factor to X10 respectively.
2. Connect the oscilloscope probe to channel 1. Attach the
probe tip and reference lead to the probe compensation
terminal and to the chassis ground terminal, then press
AUTO key.
3. Use a nonmetallic tool to adjust the trimmer capacitor on
the probe for the flattest pulse possible (see “Correct
compensation” image below). The trimmer capacitor is
located either on the probe BNC connector or above the
probe attenuation switch.

4. Connect probes to channel 2. Repeat the above steps.
This matches each probe to each channel.
