INTRODUCTION

Your new meter measures electromagnetic emissions from

power lines, computer monitors, television sets, video ma-

chinery and other electrical appliances. While the evidence

of the carcinogenic effect of such electromagnetic emis-

sions is still inconclusive, the USD EPA recommends

“prudent avoidance” of excessive exposure over long peri-

ods of time.

APPLICATION

BATTERY REPLACEMENT

This meter is designed to measure electromagnetic fields of
extremely low frequency (ELF) between 30 to 300Hz. It is
capable of measuring the electromagnetic field 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 field measurement unit is Tesla (T), Gauss
(G), milli-Gauss (mG) or micro-Tesla (µT).

FEATURES

• micro-Tesla and milli-Gauss Measurement unit display .

• Data hold and maximum hold function.

• Low battery indicator

1. Turn off the instrument.

2. Remove the battery cover.

3. Replace the battery.

4. Install the battery cover.

NOTES & PRECAUTIONS

• Never touch the meter to electrical cables or other dan-

gerous materials.

• To clean the EMF Meter use a soft dry cloth. Never use

a wet cloth, solvents or water, etc.

• Operation Altitude: Up to 2000M.

• Operating Environment: Indoor use. This instrument has

been designed for use in a pollution environment of
degree 2.

MEASUREMENT PROCEDURES

1. Press to turn on the unit.

2. Select for mG or for µT.

3. Position the front (see Figure 1) of the meter to measure
the electromagnetic waves. Change the measurement
angle or position to obtain the highest reading value
(see Figure 2 through Figure 6).

4. Read the measured value. The display of “OL” indicates
an overload. Press to select a higher range and
repeat the measurement.

MEASUREMENT PROCEDURES

Note: Due to normal environmental magnetic fields,
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.
