1.1 International Electrical Symbols
This symbol signies that the instrument is pro-
tected 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.
1.2 Receiving Your Shipment
Uponreceiving your shipment, makesurethat the con-
tents are consistent with the packing list. Notify your dis-
tributor of any missing items. If the equipment appears to
bedamaged,leaclaimimmediatelywiththecarrierand
notify your distributor at once, giving a detailed descrip-
tion of any damage. Save the damaged packing container
to substantiate your claim.

CHAPTER 2
PRODUCT FEATURES
2.1 Description
The AEMC®Models 511 and 512 are general purpose
professional clamp-on meters that measure up to the
toughest standards. These meters offer a complete set
of measurement ranges (AC Amps, AC Volts, DC Volts,
Ohms, Continuity with beeper, Frequency from V or A,
Diode Test function) and are in compliance with interna-
tional safety and quality standards to ensure professional
and reliable measuring tools. They are Auto-Ranging and
provide the best measurement range and resolution for
troubleshooting. They also have a high resolution 40A
range.
The Models 511 and 512 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 750kcmil cable or two
350kcmil cables. The large and easy-to-read 4000-count
LCD features comprehensive user information symbols,
such as low battery, polarity, overload, and an analog bar-
graph for easy trend readings. Both models are equipped
with a Data Hold function that freezes the measurement
for later viewing, Min/Max, and a fast 1ms Peak Hold
function for capture of signals.
The Model 511 is average sensing and designed for
traditional average responding electrical systems.
The Model 512 is a True RMS clamp-on that provides
RMS measurements for today’s non-linear electrical
environments.
