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.

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.

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.
