Limited Warranty
The Flexprobe®is warranted to the owner for a period of 2yearsfrom the
date of original purchase against defects in manufacture. This limited
warranty is given by AEMC®Instruments, not by the distributor from
whom it was purchased. This warranty is void if the unit has been
tampered with, abused or if the defect is related to service not performed by
AEMC®Instruments.
For full and detailed warranty coverage, please read the Warranty
Coverage Card, which is attached to the Warranty Registration Card.
Please keep the Warranty Coverage Card with your records.
What AEMC®Instruments Will Do:
If a malfunction occurs within the warranty period, you may return
the instrument to us for repair or replacement free of charge, provided we
have your REGISTRATION CARD on file. AEMC®Instruments will, at its
option, repair or replace the faulty material.
If a registration card is not on file, we will require a dated proof of pur-
chase, as well as your REGISTRATION CARD accompanied by the
defective material.

Warning
These safety warnings are provided to ensure the safety of
personnel and proper operation of the instrument.
• Read the instruction manual completely and follow all the
safety information before attempting to use or service this
instrument.
• Wear protective clothing and gloves as required.
• Use caution on any circuit: potentially high voltages and
currents may be present and may pose a shock hazard.
• Read the safety specifications section prior to using the
current probe. Never exceed the maximum voltage ratings
given.
• Safety is the responsibility of the operator. The FlexProbe®
must be used only by qualified personnel using applicable
safety precautions.
• ALWAYS de-energize the circuit before wrapping the
FlexProbe®around bare conductors, bus bars, or near live
parts. Do not wrap on live conductors.
• ALWAYS connect the electronic module to the display
device before wrapping the FlexProbe®around the sample
being tested.
• ALWAYS inspect the module, sensor, sensor cable, and
output terminals prior to use. Replace any defective parts
immediately. Use only factory parts.
• NEVER use the FlexProbe®on electrical conductors rated
above 1000V in overvoltage category III.

International Electrical Symbols
This symbol signifies that the probes are protected by double or
reinforced insulation. Use only specified replacement parts
when servicing the instrument.
This symbol signifies CAUTION! and requests that the user refer
to the user manual before using the instrument.
Receiving Your Shipment
Upon receiving your shipment, make 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.
Packaging
Your FlexProbe®consists of the following items:
• Flexible probe with in-line electronic module
• User manual
• Two 3V lithium batteries (CR2032)
• Product Warranty Registration Card with attached Warranty Card

Description
The FlexProbe®is a flexible AC current transformer composed of a
flexible sensor and an electronic module. The flexible sensor permits
measurements on conductors where standard clamp-on probes could
not be used. In particular, it can be installed in tight spaces, around
breaker panels, around cable bundles, around wide or large bus bars, or
even wrapped around irregular shapes. The Shape Memory™ feature
enables the user to “pre-shape” the sensor, somewhat, before inserting it
between or around conductors. This feature facilitates closing, enhances
user safety, and alleviates the drooping effect typically associated with
flexible sensors.
The FlexProbe®is lightweight. It does not use magnetic cores like
standard transformers. The transformation principle is based on an air
core. It presents virtually no load to the system under test, has a low
phase shift and excellent frequency response, and cannot be damaged
by overloads. The sensor assembly is waterproof and insulated for
1000V, Cat. III.
The FlexProbe®has a mV output proportional to the current measured
for direct readings on DMMs, data loggers and oscilloscopes. TRMS
measurements are taken when connected to a TRMS meter. The
FlexProbe®is insensitive to DC currents and only the AC component of
the measured signal is measured.
