• Safetyistheresponsibilityoftheoperator.TheFlexProbe®mustbe
used only by qualied personnel using applicable safety precau-
tions.
• ALWAYS de-energize the circuit before wrapping the FlexProbe®
aroundbareconductors,busbars,ornearliveparts.Donotwrapon

1.1 International Electrical Symbols
This symbol signifies that the instrument is protected by double or reinforced
insulation.
This symbol on the instrument indicates a WARNING and that the operator must
refer to the user manual for instructions before operating the instrument. In this
manual, the symbol preceding instructions indicates that if the instructions are
not followed, bodily injury, installation/sample and product damage may result.
Risk of electric shock. The voltage at the parts marked with this symbol may be
dangerous.
This symbol refers to a type B current sensor. Do not apply around or remove from
HAZARDOUS LIVE conductors without additional protective means (de-energizing
the circuit or wearing protective clothing suitable for high voltage work).
In conformity with WEEE 2002/96/EC

1.2 Definition of Measurement Categories
CAT I: FormeasurementsoncircuitsnotdirectlyconnectedtotheAC
supply wall outlet such as protected secondaries, signal level,
andlimitedenergycircuits.
CAT II: For measurements performed on circuits directly connected to
the electrical distribution system. Examples are measurements
onhouseholdappliancesorportabletools.
CAT III: For measurements performed in the building installation at
the distribution level such as on hardwired equipment in xed
installationandcircuitbreakers.
CAT IV: For measurements performed at the primary electrical supply
(<1000V) such as on primary overcurrent protection devices,
ripplecontrolunits,ormeters.
