INTRODUCTION
Warning
These safety warnings are provided to ensure the safety of personnel
and proper operation of the instrument.
• Readtheinstructionmanualcompletelyandfollowallsafetyinfor-
mation before operating this instrument.
• Onlyuseleads thatcomplywiththe IEC/EN 61010.Beforeusing
them, make sure that they are in safe working order.
• Onlyusefactorysuppliedleads.
• Neverexceedtheprotectionlimitvaluesindicatedinthespecica-
tions for each type of measurement.
• Never measure current while the test leads are connected to the
input jacks.
• Use extreme caution when measuring live systems with voltages
greater than 50VDC or 30VAC.
•
Do not perform resistance or continuity tests on a live circuit.
• Useextremecarewhenworkingaroundbusbarsandbareconduc-
tors.
• Donotusethemeterinoverrange/overloadconditions(OL).
• Whenthemultimeterclampislinkedtothemeasurementcircuits,
do not touch any unused terminals.
• Beforechanging the function, disconnect the measurement leads
from the circuit measured.

1.1 International Electrical Symbols
This symbol signies that the instrument is protected by double or rein-
forcedinsulation.Useonlyspeciedreplacementpartswhenservicingthe
instrument.
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.
1.2 Receiving Your Shipment
Upon receiving your shipment, make sure that the contents are consistent with the
packing list. Notify your distributor of any missing items. If the equipment appears
tobedamaged,leaclaimimmediatelywiththecarrierandnotifyyourdistributor
at once, giving a detailed description of any damage. Save the damaged packing
container to substantiate your claim. Do not use an instrument that appears to be
damaged.
