Typical Voltage Derating Curve (Measurement CAT II)

WARNING

The maximum input voltage rating of the probe decreases as the
frequency of the applied signal increases.

CAUTION

Refer to the oscilloscope documentation for the oscilloscope’s
acceptable input range and do not exceed this limit when using the
probes.
