INTRODUCTION

Your new meter measures electromagnetic

emissions from power lines, computer

monitors, television sets, video machinery

and other electrical appliances. While the

evidence of the carcinogenic e󰀨ect of such

electromagnetic emissions is still inconclusive,

“prudent avoidance” of excessive exposure

over long periods of time is recommended.

APPLICATION

This meter is designed to measure

electromagnetic elds of extremely low

frequency (ELF) between 30 to 300Hz. It is

capable of measuring the electromagnetic

eld radiation intensity that is produced

by electric transmission equipment, power

lines, microwave ovens, air conditioners,

refrigerators, computer monitors and video/

audio devices to name a few.

The magnetic eld measurement unit is Tesla

(T), Gauss (G), milli-Gauss (mG) or micro-

Tesla (μT).

FEATURES

• micro-Tesla and milli-Gauss Measurement

PANEL DESCRIPTION

BATTERY REPLACEMENT

Turn o󰀨 the instrument. Remove the battery

cover. Replace the battery.

Install the battery cover.

MEASUREMENT PROCEDURES

1. Press to turn on the unit.

2. Select for mG or for μT.

3. Position the front (page 6, Figure 1) of

the meter to measure the electromagnetic

waves. Change the measurement angle or

position to obtain the highest reading value

(page 6, Figure 2-6).

4. Read the measured value. The

display of “OL” indicates an overload.

Press to select a higher range and

repeat the measurement.

Note... Due to normal environmental magnetic

elds, the meter may display a reading below

0.5mG prior to measuring. This is not a

malfunction of the device.

5. To freeze the current reading displayed on

the LCD, press . Press again to

resume active measurement.

6. To retain the maximum value,

press and the reading value displayed

on the LCD will continually update the

maximum value.
