Warning

These safety wa rnings a re p rovided t o en sure the safety of

personnel and proper operation of the instrument.

 Read the in struction ma nual completely and foll ow all the

safety inform ation befo re attempting to use o r servi ce this

instrument.

 Wear protective clothing and gloves as required.

 Use ca ution on any circu it: potentially high voltag es an d

currents may be present and may pose a shock hazard.

 Read the safety spe cifications section prio r to using th e

current probe. Never exceed the max voltage ratings given.

 Safety is the responsi bility of the operator. T he A mpFlex®

must be used only by qu alified p ersonnel u sing a pplicable

safety precautions.

 ALWAYS de-energize the c ircuit before wrapping the

AmpFlex® around b are conductors, b us ba rs, or near live

parts. Do not wrap on live conductors.

 ALWAYS c onnect the elec tronic module to the dis play

device before wrap ping t he AmpFl ex® aro und th e sample

being tested.

 ALWAYS inspec t the module, sens or, s ensor cable, and

output termin als pri or to u se. Repl ace any defective parts

immediately. Use only factory parts.

 NEVER us e the AmpFlex ® on ele ctrical conductors rated

above 600V CAT IV; 1000V CAT III.

International Electrical Symbols

This symbol signifies that the current probe is p rotected by double

or reinforced insulation. Use o nly factory spe cified repla cement

parts when servicing the instrument.

This symbol signifies CAUTION! and requests that the user refer to

the user manual before using the instrument.

This symbol refers to a type B current sensor. Do not apply around

or remove from HAZARDOUS LIVE conductors without additional

protective means (de-energizing the circuit or wearing protective

clothing suitable for high voltage work).

AmpFlex® - Flexible AC Current Probes

Description

The AmpFlex® is a flexible AC current transformer composed of a flexible

sensor a nd an electronic m odule. The flexib le sen sor permits

measurements on condu ctors where standard clamp-on probe s could

not be used. In pa rticular, it can be installed in ti ght spaces, around

breaker panels, around cable bundles, around wide or large bus bars, or

even wrapp ed arou nd irregula r sh apes. The Shap e Memory feature

enables the user to “pre-shape” the sensor before inserting it between or

around conductors. This feature facilitates closing, enhances user safety,

and all eviates the drooping effe ct ty pically a ssociated with flexible

sensors.

The AmpFle x® is lightwe ight and do es not u se magneti c co res like

standard t ransformers. Th e tran sformation pri nciple is ba sed on an ai r

core. It presents virtually no load to the system u nder te st, has a low

phase shift and excellent frequency response, and cannot be damaged

by overloads.

The se nsor assembly is waterproof and insul ated for 600V CAT IV;

1000V CAT III. The AmpFl ex® meets EN 61010-1, is CE m arked, and is

designed wit h material s a nd co mponents to meet internatio nal agency

approvals.

The Amp Flex® ha s a n mV output proportional to th e current m easured

for direct readings on DMMs, data l oggers, oscilloscopes, and power or

harmonic meters. TRMS m easurements are taken when connected to a

TRMS m eter. The Amp Flex® is in sensitive to DC currents an d onl y the

AC component of the measured signal is measured.

The length of the flexible sensor can be selected in lengths of 24" , 36",

and 48" in le ngth. Consult the factor y for cu stom lengths, ranges and/or

features.
