To Compensate Probes

Perform this adjustment to match your probe to the input channel. This should be

done whenever you attach a probe for the first time to any input channel.

1. Set the Probe menu attenuation to 10X. Set the switch to 10X on the probe and

connect the probe to channel 1 on the oscilloscope. If you use the probe

hook-tip, ensure a proper connection by firmly inserting the tip onto the probe.

Attach the probe tip to the PROBE COMP connector and the reference lead to the

PROBE COMP Ground connector, turn on channel 1, and then press AUTO.

2. Check the shape of the displayed waveform.

3. If necessary, use a non-metallic tool to adjust the trimmer capacitor on the probe

for the flattest square wave possible as displayed on the oscilloscope.

4. Repeat as necessary.

WARNNING: To avoid electric shock while using the probe, be sure the

perfection of the insulated cable, and do not touch the metallic portions of

the probe head while it is connected with a voltage source.
