1.1 International Electrical Symbols
Signifies that the instrument is protected by double or reinforced
insulation.
On the instrument, this symbol 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 sym-
bol may be dangerous.
Refers to a type A current sensor. This symbol signifies that application
around and removal from HAZARDOUS LIVE conductors is permitted.

PRODUCT FEATURES
2.1 Description
The AEMC®Model 514 is a general purpose professional
clamp-on meter that measures up to the toughest stan-
dards. This meter offers a complete set of measurement
ranges including AC Amps, AC Volts, DC Volts, Ohms,
Continuity with beeper, Frequency from V or A, Diode
Test function and also uses Hall Effect sensor technology
that provides both DC and AC current measurements to
1000A. The Model 514 is in compliance with international
safety and quality standards to ensure professional and
reliable measuring tools.
The Models 514 is sized for comfortable, one-handed
operation. The tapered and hooked jaw design facili-
tates 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 fea-
tures comprehensive user information symbols, such as
low battery, polarity, overload, and an analog bargraph
for easy trend readings. It is 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 514 is a True RMS clamp-on that provides
RMS measurements for today’s non-linear electrical envi-
ronments.
