1.0 PRODUCT OVERVIEW
1.1 Introduction
The Model HI-3520 RF Radiation Badge (see Figure 1) is
a portable, battery operated, non-ionizing radiation hazard
detector intended for personal use. It detects
electromagnetic radiation from RF and microwave sources
in the frequency range from 1 to 18 GHz and alerts the
user to potentially hazardous fields. The Model HI-3520
enables the user to set the alarm warning level anywhere
in the range from 0.2 to 20 mW/cm2. In addition, the
user can choose either of two measurement modes:
instantaneous exposure level or a six minute average
measurement. Both modes are displayed on a three digit
LCD panel along with a ten segment bar graph normalized
to the selected alarm warning level. Electrical,
mechanical and performance characteristics are described
in section 2.0.
The Model HI-3520 is intended for use by personnel who
work with or service RF and microwave equipment such
as:
! Microwave Ovens
! Medical Equipment
! Radar Installations
! Microwave Heaters and Dryers
! Communication Systems
! Electronic Warfare Systems
