PRODUCT FEATURES

2.1 Description

The AEMC® Models 670 and 675 are general purpose

professional clamp-on meters that measure up to the

tougheststandards.Thesemeterso󰀨eracompletesetof

measurementranges(ACAmps,DCAmps[675only],AC

Volts,DCVolts,Ohms,Continuitywithbeeper,Frequency

from V or A, and Temperature) and are in compliance

with international safety and quality standards to ensure

professionalandreliablemeasuringtools.

Thesemetersaredesignedtomeasureanddisplayamps

and volts at the same time. They are also auto-ranging

andprovide the bestmeasurement rangeand resolution

fortroubleshooting.

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

measurementforlaterviewing,Min/Max,andPeakfunction

forcaptureofsignals.

TheModel670and675areTrueRMSclamp-onmeters

that provide RMS measurements for today’s non-linear

electrical environments.
