Symbols
These safety and electrical symbols may appear on the product or in this guide:
Symbol Description
Direct current
Earth (ground) terminal
Terminal can be used to make a
measurement ground connection.
The terminal is NOT a safety or
protective earth.
Possibility of electric shock
Caution
Appearance on the product
indicates a need to read these
safety and operation instructions.
Do not dispose of this product
as unsorted municipal waste.
WARNING
To prevent injury or death only 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.
Maximum input ranges
The table and frequency derating plot below indicate the full-scale measurement
range and overvoltage protection range for these probes. The full-scale
measurement ranges are the maximum voltages that can be accurately
measured by the probe. The overvoltage protection 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 below and do take all necessary safety precautions when
working on equipment where hazardous live voltages may be present.

Overvoltage protection
(voltage that will not damage)
X10
600 V DC + peak AC
600 V DC + peak AC
X1
42.4 V DC + peak AC
200 V DC + peak AC
WARNING
To avoid overloading the probe, note that its maximum input voltage
rating decreases as the frequency of the applied signal increases.
