Safety descriptions found throughout this user guide:
A WARNING identifies conditions or practices that could
result in death or injury. To prevent injury or death only
2

qualified personnel should use this product, only as
instructed and with only accessories supplied or
recommended. Protection provided by the product may be
impaired if used in a manner not specified in this guide.
A CAUTION identifies conditions or practices that could
result in damage to connected product or equipment.
Maximum input ranges
The full-scale measurement ranges are the maximum voltages that can
be accurately measured by the probe for safe operation. The
overvoltage ranges are the maximum voltages that will not damage the
probe.
WARNING To prevent electric shock, do not connect the
probe to voltages exceeding the levels specified in this user
guide and do take all necessary safety precautions when
working on equipment where hazardous live voltages may
be present.
WARNING Do not connect to a mains voltage or a derived
voltage that can carry the overvoltage transients that may
be present. Note that the probe's maximum input voltage
rating decreases as the frequency of the applied signal
increases. This probe does not carry a measurement
category rating.
Grounding
WARNING Do not ever connect the ground input to, or allow
it to touch, any electrical potential other than ground. To
prevent death or personal injury, always measure that there
is no significant DC or AC voltage between the probe
ground and the point to which you intend to connect it.
3

CAUTION Applying a voltage to the ground input is likely to
cause permanent damage to the probe or other connected
equipment.
Environment
WARNING To prevent death or injury, do not use near
explosive vapor or gas.
CAUTION To prevent damage to the probe, always operate
and store your probe according to the levels specified in this
guide.
Care of the product
The probe contains no user-serviceable parts.
WARNING To prevent death or injury, do not try to open any
part of the assembly, do not use the product if it appears to
be damaged in any way, and stop use immediately if it
behaves abnormally.
CAUTION Always handle with care to avoid injury from the
sharp tip. Ensure that the probe is completely dry before
use. Do not allow liquids to enter the probe. Take care to
avoid mechanical stress or tight bends on the arm and
cable connecting the probe head to the oscilloscope.
Mishandling will degrade performance and measurement
accuracy and is not covered by the warranty. Avoid all kind
of mechanical shock to the probe assembly.

*The probe and cable are not impedance matched and are suitable for measurements below
10MHz, frequencies above 10 MHz can still be measured but with increased signal distortion
on rising and falling edges using oscilloscope. The probe and cable are tested above 25
MHz with correct data decoding with common logic analyzer.
