❙ 0 (instruments without measured measurement
category): Other circuits that are not connected
directly to the mains .
❙ Measurement CAT II: Measurements on circuits
electronically directly connected to the mains (e .g .
household appliances, power tools, etc .)
❙ Measurement CAT III: Measurements in building
installations (e .g . power distribution installations,
power switches, firmly installed sockets, firmly
installed engines etc .) .
❙ Measurement CAT IV: Measurements at the
source of the low voltage installations (e .g . meters)
Symbols
The following symbols may appear on the product
or in this instruction manual:
Caution, risk of danger . Refer to manual .
Caution, risk of electric shock .
IEC Pollution Degrees
❙ Pollution Degree 1 - No Pollution or only dry, non
conductive Pollution . The Pollution has no
influence.
❙ Pollution Degree 2 - Only non-conductive
Pollution . Occasionally, however, a temporary
conductivity caused by condensation must be
accepted .
❙ Pollution Degree 3 - Conductive Pollution occurs
or dry, non-conductive Pollution occurs which
becomes conductive due to condensation which
is to be expected .

Safety Information

Read the following safety precautions to avoid per-
sonal injury and to prevent this product or products
connected with it from fire or damage. This probe
should be used by qualified personnel only.
Indoor use only:
This probe is intended for an indoor use only . Do
not use this probe in wet or damp environments .
Keep the surface clean and dry . Do not use the
probe in explosive atmospheres .
Connecting the probe:
Before connecting the probe to a circuit under test
make sure the probe is connected to a grounded
measurement instrument .
Using the probe:
Do not use this probe with voltages exceeding the
limits in the data sheet . This probe should not be
used in circuits with measurement category II, III
or IV . With increasing frequency the voltage on the
probe tip should not be higher than illustrated in the
derating curve .
If the manufacturers specifications are not
observed, this can result in electric shock,
fire and/or serious personal injury, and in
some cases, death.
The probe lead should not be connected to any
other potential than earth ground .
