    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.

  • Page 4: Introduction

    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.

  • Page 5: Application

    The characteristic of electromagnetic fields : Electromagnetic fields propagate as waves and travel at the speed of light (c). The wavelength is proportional to the frequency. c (speed of light) λ(wavelength) = f (frequency) If the distance to the field source is less than three wavelength, then we are usually in the near-field.

  • Page 6: Features

    2-3 Features The meter is a broadband device for monitoring high-frequency radiation in the range from 10MHz to 8GHz. The non-directional electric field and high sensitivity also allow measurements of electric field strength in TEM cells and absorber rooms. The unit of measurement and the measurement types have been selected to expressed in units of electrical and magnetic field strength and power density.

  • Page 13: Use E-Field Sensor

    4-3 Use E-field sensor The actual 3-channel sensor is located in the head part of the meter. The three voltages generated by the sensor are fed back to the meter. In far-fields, an E-field sensor is preferable due to the greater bandwidth. The E-field sensor for frequencies is from 10MHz to 8GHz.
