１．SafetyWarnings
○This instrument has been designed and tested according to IEC
Publication 61010；Safety Requirements for Electronic Measuring
Apparatus. This instruction manual contains warnings and safety
rules which must be observed by the user to ensure safe operation of
the instrument and to retain it in safe condition. Therefore, read
through these operating instructions before starting using the
instrument.
WARNING
●Read through and understand instructions contained in this manual
before starting to use the instrument.
●Save and keep the manual handy to enable quick reference
whenever necessary.
●Be sure to use the instrument only in its intended applications and
to follow measurement procedures described in the manual.
●Be sure to understand and follow all safety instructions contained
in the manual.
Be sure to observe the above instructions.
Failure to follow the above instructions may cause injury, instrument
damage and/or damage to equipment under test.
○The symbol indicated on the instrument means that the user
must refer to related parts in the manual for safe operation of the
instrument. Be sure to carefully read the instructions following
each symbol in this manual.
DANGER is reserved for conditions and actions that are likely to
cause serious or fatal injury.
WARNING is reserved for conditions and actions that can cause
serious or fatal injury.
CAUTION is reserved for conditions and actions that can cause
minor injury or instrument damage.

DANGER
●Never make measurement on the circuit above 750VAC or 1000VDC.
●Do not attempt to make measurement in the presence of flammable
gasses, fumes, vapor or dust. Otherwise, the use of the instrument
may cause sparking, which can lead to an explosion.
●Transformer jaw tips are designed not to short the circuit under
test. If equipment under test has exposed conductive parts,
however, extra precaution should be taken to minimize the
possibility of shorting.
●Never attempt to use the instrument if its surface or your hand is wet.
●Do not exceed the maximum allowable input of any measurement
range.
●Never open the battery compartment cover and the instrument case
when making measurement.
●Verify proper operation on a known source before use or taking
action as a result of the indication of the instrument.
WARNING
●Never attempt to make any measurement if any abnormal conditions
are noted, such as broken case, cracked test leads and exposed
metal parts.
●Do not turn the function selector switch with test leads connected to
the instrument.
●Do not install substitute parts or make any modification to the
instrument. Return the instrument to your distributor for repair or recalibration.
●Do not try to replace the batteries if the surface of the instrument is wet.
●Always switch off the instrument and make sure to disconnect test leads
before opening the battery compartment cover for battery replacement.
CAUTION
●Always make sure to check the function selector switch is set to an
appropriate position before starting measurement.
●Always make sure to insert the plug of each lead fully into the
appropriate terminal on the instrument.
●Be sure to set the function selector switch to the "OFF" position
after use. When the instrument will not be in use for a long period,
place it in storage after removing the batteries.
●Do not expose the instrument to the direct sun, high temperature or
dew fall.
●Use a cloth dipped in water or neutral detergent for cleaning the
instrument. Do not use abrasives or solvents.
―28―
●Tear-drop-shaped jaws for ease of use in crowded cable areas and
other tight places.
●Accurate true-RMS reading of AC current or voltage with distorted
waveform (MODEL2002R)
●Provides a wide measuring range from 0 up to 2000A.
●Terminal cover to avoid the use of an incorrect terminal.
●Measures current variation as short as 10 msec with peak-hold
feature.
●Provides output to a chart recorder for current variation recording.
●Designed to international safety standards.
IEC61010-1 (CAT.Ⅲ 600V /CAT.Ⅱ 1000V Pollution degree 2)
IEC61010-031, IEC61010-2-032
●Data hold function to allow easy readings in dimly lit or hard-to-read
locations.
●Sleep feature to conserve battery power.
●Permits easy continuity check with a beeper.
●Provides a dynamic range of 4,000 counts full scale.
●Provides wide measuring range of voltage and resistance in auto-
ranging.
●Wide frequency range from 40Hz to 1kHz (Current measuring range:
0-1500A).
●Transformer jows fitted with guard to further improve safety.
●Protected throughout by double or reinforced insulationF.
