Limited Warranty

Archived 4/2/10

Holaday Industries, Inc. warrants each model HI-3510 Radiation
Badge Broadband Electromagnetic Radiation Detector to be free
from defects in material and workmanship for a period of one
year from the date of shipment to the purchaser. This warranty
extends to the original purchaser only, and does not apply to the
batteries or to any products or parts subject to misuse, neglect,
accident, unauthorized service or abnormal conditions of
operation.

In the event an instrument covered by this warranty fails,
Holaday Industries, Inc. will, without charge, repair and
recalibrate the instrument if returned to their factory within one
year of the original purchase—provided that Holaday Industries'
examination discloses, to its satisfaction, that the product is
defective. Holaday Industries, Inc., may, at its option, replace
the product in lieu of repair. If the defect was caused by misuse,
neglect, accident, unauthorized service or abnormal conditions of
operation, repairs will be billed at a nominal cost. In such cases,
an estimate will be provided before work is started, if requested
by the purchaser.

For warranty service, contact Holaday Industries, Inc. Provide
the serial number of the instrument and complete details
regarding the failure mode. You will then be given either service
information or shipping instructions. Return the instrument to
the factory, transportation prepaid. Repairs will be made at the
factory and the instrument will be returned to you, transportation
prepaid. Holaday Industries, Inc., assumes no responsibility for
loss of, or damage to, products in transit.

Warning!

EXTREME CAUTION IS ADVISED WHEN WORKING IN
ENVIRONMENTS WHERE HIGH-INTENSITY ELECTROMAGNETIC
FIELDS MAY EXIST AND WHERE CONTACT WITH HIGH VOLTAGE
OR HIGH CURRENT CIRCUITS OR APPARATUS IS POSSIBLE.
ACCIDENTAL CONTACT WITH OBJECTS OR CIRCUITS OPERATING
AT HIGH VOLTAGES OR HIGH CURRENTS CAN BE LETHAL!
HOLADAY INDUSTRIES, INC. ASSUMES NO LIABILITY FOR ANY

WARNING:

Harmful effects may result from exposure to
electromagnetic (EM) radiation in the frequency range
from 300 kHz to 100 Ghz.

Among the more widely accepted safety standards are
those established by the American National Standards
Institute ("ANSI"), C95.1-1991, and the National
Radiological Protection Board (“NRPB”), NRPB-G11, of
the United Kingdom. Each of the two standards
establishes different safety limits for the general public
and industrial environments. Of particular significance is
the 10 to 300 MHz frequency range, where the limits are
most stringent, especially for the general public, and are
set to an equivalent power density of 0.2 mW/cm2. At
higher frequencies, the limits are as high as 1 mW/cm2,
whereas at frequencies below 3 MHz, the limits are set to
100 mW/cm2.

Note that the aforementioned safety standards cannot be
measured by the Model H600A, which is a warning, and
not a measuring device. Suitable measuring devices exist
in the marketplace. Please contact the factory for
additional information on this subject.

The three common units of measurement for
characterizing electromagnetic energy are power density
in mW/cm2, electric field ("E-field") in V/m and magnetic
field ("Hfield") in A/m. At sufficiently large distances
from the source of radiation, the E-field and H-field
components have a fixed mathematical relationship.
Thus, the measurement of any one of these units in free
space is sufficient to determine the radiation level and
derive the other two. At frequencies nominally above 1

GHz, most radiation fields are of this character known as
the free space condition. The free space relationships are
shown below:

To convert:

Power Density P in mW/cm2 to Electric

Field E in V/m: E=61.4 (P

0.5

)

Power Density P in mW/cm2 to

Magnetic Field H in A/m: H=0.163 (P

0.5

)

Always approach an unknown field cautiously, starting
from as far away as possible and extending the RF
Radiation Badge at arm's length toward the energy
source. Allow two to three seconds for the instrument to
respond. Observe all safety precautions. Do not walk
into a suspected radiation field until the power density is
determined to be safe. Ensure that the unit is in the
"Instantaneous" Measurement Mode (see paragraph 3-4­3-2), not the "Average" Measurement Mode.

SECTION I

INTRODUCTION

1-1 General

The Model HI-3510 Broadband Electromagnetic Radiation
Detector (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

0.05 to 2.5 GHz and alerts the user to potentially
hazardous fields. The Model HI-3510 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 table 1
below.

The Model HI-3510 is intended for use by personnel who
work with or service RF and microwave equipment such
as:

Ž Microwave Ovens
Ž Medical Equipment
Ž Microwave Heaters and Dryers
Ž Communication Systems
Ž Cellular Telephones
