Extech Instruments EMF450 Quick Start

Quick Start (en)
Introduction
This meter simultaneously measures and displays magnetic field,
electrical field, and RF strength, expressed in units of electrical and
magnetic field strength and power density.
Safety
• The field strength near radiators increases proportionally to the
inverse cube of the distance.
• Field strength meters can underrate pulsed signals, particularly
with radar signals.
• For indoor use; pollution level 2.
CAUTION
• Use caution near powerful radiation sources.
• Do not operate near combustible gases or in damp environments.
