Warning
These safety warnings are provided to ensure the safety of person-
nel and proper operation of the instrument.
•Read this instruction manual completely before attempting to use
or service this instrument and follow all the safety information.
•Use caution on any circuit: Potentially high voltages and cur-
rents may be present and may pose a shock hazard.
•The instrument must not be operated beyond its specified oper-
ating range.
• Safety is the responsibility of the operator.
•Never open the back of the instrument while connected to any
circuit or input.
•Always make connections from the instrument to the circuit
under test.
•Always inspect the instrument and accessory leads for service-
ability prior to use, and replace defective parts immediately.
•Do not use the meter or any test leads, connectors, probes or
clips if they look damaged.
•Never use the clamp-on meters on electrical conductors rated
above 600 Vrms.
• Never make resistance measurements on a live circuit.
• Never make diode tests on a live circuit.
•Do not have voltage or current inputs connected at the same time.

International Electrical Symbols
This symbol signifies that the Models 701 and 703 are protect-
ed throughout by double or reinforced insulation. Only use
specified replacement parts when servicing the meter.
This symbol signifies CAUTION! and requests that the user
refer to the user manual before using the meter.
Receiving Your Shipment
Upon receiving your shipment, be sure that the contents are consistent
with the packing list. Notify your distributor of any missing items. If the
equipment appears to be damaged, file a claim immediately with the
carrier and notify your distributor at once, giving a detailed description
of any damage.

Description
The AEMC®Instruments Clamp-on Multimeter Models 701 and 703 are
general purpose professional clamp-ons. A strong mechanical case
design, quality materials (GE Lexan®), full ranges and compliance to
international safety and quality standards insure a professional and reli-
able measuring tool. Both models are autoranging, and provide AC
amperes and AC volts, plus DC volts, ohms, continuity with a beeper,
and a diode test function. The Model 703 also has a frequency function.
Both models are equipped with a large and complete 4000 count LCD
with annunciator symbols such as HOLD, Low Battery, Max etc. for easy
operation.
The Model 701 is average sensing RMS calibrated and designed for the
traditional average responding electrical systems. The Model 703 is a
True RMS clamp-on that provides RMS measurements for today’s non-
linear electrical environments. Both clamp-ons are supplied with test
probe terminated test leads, a soft carrying case, a 9 V battery and a
user manual.
We designed and built the Models 701 and 703 for reliability: the right
size; the right functions, display and performance; the right single-hand-
ed operation; the right professional tool.
