Introduction
Thank you for selecting the Extech EMF510 EMF Meter. This instrument measures
electromagnetic field radiation levels near power lines, appliances and industrial devices.
Electromagnetic radiation is a ubiquitous type of energy that takes many forms such as radio
waves, microwaves, X-rays, and gamma rays. The EMF510 measures radiation from voltage,
current, electrical, and magnetic fields.
This device is shipped fully tested and calibrated and, with proper use, will provide years of
reliable service.
Features
• Backlit LCD
• Compact, light-weight, easy-to-use, ergonomic design
• Wristlet for easy, one-handed operation
Safety
Please read the entire User Manual and Quick Start before operating this device. Use the meter
only as specified and do not attempt to service or open the meter housing. Do not allow children
to handle the meter. Please dispose of batteries and meter responsibly and in accordance with
all applicable laws and regulations.
WARNINGS
• Use caution when working in the vicinity of powerful radiation sources.
• Persons with electronic implants (e.g. cardiac pacemakers) should avoid powerful radiation
sources.
• Observe all relevant safety regulations.
• Carefully read the operating instructions for equipment generating or conducting
electromagnetic energy that will be measured.
• Do not operate near combustible gases or in damp environments.
• Be aware that the field strength in the near vicinity of radiators increases proportionally to the
inverse cube of the distance. This means that enormous field strengths can result in the
immediate vicinity of small radiation sources (e.g. leaks in waveguides or inductive ovens).
• Field-strength measurement devices can underrate pulsed signals, particularly with radar
signals, in which case significant measurement errors can result.
• All field-strength measuring devices have a limited specified frequency range. Fields with
spectral components outside of this frequency range are generally incorrectly evaluated and
tend to be underrated. Before using field-strength measuring devices be certain that all field
components to be measured lie in the specified frequency range of the measuring device.
