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 A current sensor. This symbol sig-
nifies that application around and removal from HAZARDOUS
LIVE conductors is permitted.
Ground.
In conformity with WEEE 2002/96/EC.
1.2 Definition of Measurement Categories
CAT II: Formeasurementsperformedoncircuitsdirectly
connected to the electrical distribution system.
Examples are measurements on household
appliancesorportabletools.
CAT III: For measurements performed in the building
installation at the distribution level such as on
hardwired equipment in xed installation and
circuitbreakers.
CAT IV: For measurements performed at the primary
electrical supply (<1000V) such as on primary
overcurrent protection devices, ripple control
units,ormeters.

PRODUCT FEATURES
2.1 Description
The AEMC® Models 670 and 675 are general purpose
professional clamp-on meters that measure up to the
tougheststandards.Thesemetersoeracompletesetof
measurementranges(ACAmps,DCAmps[675only],AC
Volts,DCVolts,Ohms,Continuitywithbeeper,Frequency
from V or A, and Temperature) and are in compliance
with international safety and quality standards to ensure
professionalandreliablemeasuringtools.
Thesemetersaredesignedtomeasureanddisplayamps
and volts at the same time. They are also auto-ranging
andprovide the bestmeasurement rangeand resolution
fortroubleshooting.
The Models 670 and 675 are sized for comfortable,
one-handed operation. The tapered and hooked jaw
design facilitates maneuvering in crowded wiring and
breaker panels, making it easy to select conductors.
The jaw opening accommodates one 750 kcmil cable or
two 350 kcmil cables. The large and easy-to-read 9999-
count LCD features comprehensive user information
symbols, such as low battery, polarity, overload, and an
analog bargraph for easy trend readings. Both models
are equipped with a Data Hold function that freezes the
measurementforlaterviewing,Min/Max,andPeakfunction
forcaptureofsignals.
TheModel670and675areTrueRMSclamp-onmeters
that provide RMS measurements for today’s non-linear
electrical environments.
