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).

Denition of Measurement Categories (CAT)

CAT IV corresponds to measurements taken at the source of low-voltage

installations.

Example: power feeders, counters, and protections devices.

CAT III corresponds to measurements on building installations.

Example: distribution panel, circuit-breakers, machines, or xed industrial

devices.

CAT II corresponds to measurements taken on circuits directly connected to low-

voltage installations.

Example: power supple to domestic electrical appliances and portable tools.

1.1 PRECAUTIONS FOR USE

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.

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 AmpFlex®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.

The AmpFlex®is lightweight and 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, has excellent

frequency response, and cannot be damaged by overloads.

CAT III. The AmpFlex®meets EN 61010-1, is CE marked, and is designed with

materials and components to meet international agency standards.

The AmpFlex®has an mV output proportional to the current measured for

direct readings on DMMs, data loggers, oscilloscopes, and power or harmonic

meters. TRMS measurements are taken when connected to a TRMS meter.

The AmpFlex®is insensitive to DC currents and only the AC component of the

measured signal is measured.
