1. SAFETY INFORMATION
CAUTION
•Before making a measurement, check if the low battery symbol ( + ) is shown on the display as
soon as the meter is switched on. Change the battery if the symbol is displayed.
•In the case of prolonged storage, it is preferable to remove the battery from the meter.
•Avoid shaking the meter, particularly in the measurement mode.
•The accuracy and function of the meter may be adversely affected by the specified limits outside and
improper handling.
DANGER !
•In some cases, work in the vicinity of powerful radiation sources can be a risk of your life.
•Be aware that persons with electronic implants(e.g. cardiac pacemakers) are subject to particular dangers in
some cases.
•Observe the local safety regulations of the facility operation.
•Observe the operating instructions for equipment which is used to generate, conduct or consumer
electromagnetic energy.
•Be aware that secondary radiators (e.g. reflective objects such as a metallic fence) can cause a local
amplification of the field.
•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. leak in waveguides, inductive ovens).
•Field strength measuring device can underrate pulsed signals. Particularly with radar signals, significant
measurement errors can arise.
•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, you should thus be certain that all field components to be
measured lie in the specified frequency range of the measuring device.
2. INTRODUCTION
2.1. Fundamentals
Electromagnetic pollution
This Meter used to indicate electromagnetic pollution generated artificially. Wherever there is a voltage or
a current, the electric (E) and magnetic (H) fields arise. All types of radio broadcasting and TV transmitters
produce electromagnetic fields, and they also arise in industry, business and the home, where they affect
us even if our sense organs perceive nothing.
Electric field strength (E):
A field vector quantity that represents the force (F) on an infinitesimal unit positive test charge (q) at a point
divided by that charge. Electric units of volts per meter (V/m). field strength is expressed in
Use the units of electric field strength for measurements in the following situations:
•In the near-field area of the source.
•Where the nature of the electromagnetic field is unknown.
