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.

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.

4Clamp-on Multimeters Models 701 & 703
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.

AC Current Measurements
1. Turn the rotary switch to the current measurement function A~.
2. Press the trigger to open the instrument jaws. Clamp the jaws
around the conductor. For the most accurate readings, align the con-
ductor with the centering marks on the jaws.
3. Take the reading from the display. Current measurements are pos-
sible from 1 A to 700.0 A.
4. If you have the instrument positioned so that you cannot read the
display, press the HOLD button on the side of the instrument to
freeze the reading. Remove the clamp-on and read.

AC and DC Voltage Measurements
1. Turn the rotary switch to the voltage measurement function to mea-
sure AC or DC volts.
2. Insert the red test lead into the + jack and the black test lead into
the COM jack. Select the appropriate termination (test probes or
clips).
3. Touch or connect the voltage test leads to the circuit under test.
4. Take the reading from the display. Voltage measurements are pos-
sible from 0.0 to 600 V.

MAX Value Measurements
1. With the switch in theAAC, VAC or V DC function, push and release
the MAX button (positive MAX value will be displayed).
2. Take the reading.
For the Model 703
There is approximately a 2-second delay before the MAX indication is
shown on the display.
When taking repetitive MAX measurements, wait approximately 5 sec-
onds between measurements.
Resistance Measurements
1. Turn the switch to the Ωfunction.
2. Connect the red lead to the + terminal and black to the COM
terminal.
3. Take the reading from the display. Resistance measurements are
possible from 0 to 4 kΩ.
WARNING: Check that the circuit is not live. Do not test
resistance on a live circuit.
