1. FEATURES
The EMF tester is designed to provide user a quick, reliable and easy way to measure electromagnetic field
radiation levels around power lines, home appliances and industrial devices. The EMF tester is a cost
effective hand-held instrument that was designed and calibrated to measure electromagnetic field
radiation at different bandwidths down to 50Hz/60Hz. Display micro Tesla & milli Gauss in the same tester.
Data hold / Peak hold / on-line computer / data record function. Comply with CE.
2. APPLICATIONS
This EMF tester is specifically designed to determine the magnitude of electromagnetic filed radiation
generated by power lines, computer’s monitor, TV sets, video machinery and many other similar devices.
3. CAUTION OF ELECTROMAGNETIC FIELD EXPOSURE
Claims by some scientists that long term exposure to electromagnetic field may be the cause of childhood
leukemia & other forms of cancer. Complete answers to any of these and related questions are not
currently available. At the present time, the most common practice is to avoid excess exposture over long
period of time. “Prudent Avoidance” as stated by the Environmental Protection Agency (EPA) USA is
recommended.

5. NAME OF PARTS AND POSITIONS
1). Display panel 7). LCD state record button
2). Power button 8). Sensor position
3). Peak Hold function 9). Battery cover
4). Data Hold function 10). Carrying clip
5). Range selector button 11). RS-232
6). Milli Gauss/Micro Tesla button
6. MEASURING PROCEDURE
1). Press the button of power and set the “Range”, “Gauss”, “Tesla”by pressing the buttons
according to the measuring requirements. Tester is now ready to take the measurement. Due to
the electromagnetic interference of the environment, the display reading may show the reading
before testing, for example the reading would lower than 0.5m Gauss. This is not malfunction of
the tester.
2). With the tester in hand, move slowly towards to the object under measurement until it is
physically touched. Notice how the field intensity increases as you move closer to the object.
3). Position the EMF tester at different angles to the object while measuring. Users would observe
how this may affect your reading.
4). By trying different angles approaching the object while measuring to get Max. If the power of
object was turned off during the measurement, the reading of EMF tester should return to zero,
unless there is the electromagnetic from other sources are detected.

7. DATALOGGING (METER)
1). To clear Datalogger memory: Press and hold the (RECORD) button then turn the “Power”on.
2). To trigger continuous Datalogging: Press (RECORD) button for one second then release.
Now the unit symbol glittering (0.4s) show on LCD and the metes begin is recording.
3). To stop continuous Datalogging: Press (RECORD) button once again LCD show the unit
symbol not glittering and stop recording.
4). Before download the recorded data to PC, please turn off the meter then turn on the meter.
5). Memory recording full: LCD show the unit symbol glittering (0.2s) and stop recording.
8. RECOMMENDATION
It is recommended to measure the presence of the electromagnetic field inside and outside of your
home and business locations regularly. As “hot spots”are detected by the EMF tester,
rearrangement of the living and working areas is lightly recommended. Always try the best to avoid
long term exposure in the strong electromagnetic field.
9. BATTERY CHECK-UP & REPLACEMENT
1). When the left corner of the LCD display shows “”, it indicates the output of battery is less than
4.0V ~ 4.5V. Replacement of the battery is then needed. However, measurement could still be
taken for next few hours before the tester is unavailable.
2). Open the battery cover at the back of tester and remove the battery.
3). Replace with four AAA-size alkaline batteries and reinstate the cover.
4). Prevention of Battery Fluid Leakage: When the battery power is low, replace the new battery in
order to avoid the further battery fluid leakage possibility. When the meter will not be in use for the
long period of time, please remove the batteries out of meter to prevent the possibility of battery
fluid leakage damage.
