Datasheet
This datasheet supersedes all previously published material. Specifications that are defined typical
are not guaranteed and are published as general information to the user. The instrument should
have warmed up for at least 20 minutes and the environmental conditions must not exceed the spe-
cified limits of the probe. Note that specifications are subject to change without notice.

Voltage derating
(1) Connect to oscilloscope with an input impedance of 1 MΩ ± 1 %.
(2) at 15 pF input capacitance of the measuring instrument.
(3) As defined in IEC 61010-031.
Note that the max. input voltage
rating of the probe decreases as
the frequency of the applied signal
increases.
