appliances in places including medical institutions, schools and residential districts, where people usually stay for a long time, to prevent patients, babies and senior citizens from exposure to high electromagnetic waves. An electromagnetic wave simply means the wave motion of the electromagnetic field (EMF). The change in electric fields produces magnetic fields, and the change in magnetic fields can also generate electric fields. The fluctuation of correlation between each other is known as “electromagnetic waves", which is a form of energy similar to light and heat that can be transmitted either by radiation in the air or by an electric conductor. It is suggested that rearrangements should be made in homes and work locations where the strongest electromagnetic fields are detected in order to avoid prolonged exposure to excessive electromagnetic fields.

fields of extremely low frequency (ELF) of 30 to 2000Hz. z It is capable of measuring the magnetic field radiation intensity that is produced from electric transmission equipment, power lines, microwave ovens, air conditioners, refrigerators, computer monitors, video/audio devices and so forth. z The magnetic field unit is Tesla (T), Gauss (G), milli-Gauss (mG) or micro-Tesla (μT). 1 T＝10,000 G 1 G＝1,000 mG 1μT＝10 mG

wide range of ELF magnetic fields, independent of measurement angle. z The tester is designed to provide a quick, reliable and easy way to measure magnetic field radiation levels around power lines, home appliances and industrial devices. z The tester is a cost-effective hand-held instrument that was designed and calibrated to measure magnetic field radiation at different bandwidths from 30Hz to 2000Hz. z Display microTesla(uT) or milliGauss(mG) units. z Data hold (HOLD), maximum Hold (MAX), and minimum Hold(MIN) function. z Auto range or manual range select mode. z Datalogging capacity with Memory Size：500 data sets (Model 192) or 9999 data sets(Model 192D). z USB PC interface (192D). z Time and calendar function. z Low battery indication “ ”. z Over load display “OL”. z Auto power OFF function .

z Press “ ” key turn on the meter, press “ ” key again to turn OFF the meter. z Press “ ” key to select milli-gauss (mG) or micro-tesla (µT) unit. z Position the front of the meter to measure the magnetic waves. z Read the measured value. When manual range mode is selected, LCD will shown the mark, The display of “OL” on the highest position indicates there is an overload on the reading. Press “ ” to select a higher range for measurement again. z The default value display is triaxial total magnetic field reading. Press “ ” key to toggle between independent three single-axis magnetic field readings and triaxial total magnetic field reading. z To lock and keep the reading displayed on the LCD, press “ ” or press “ ” again to unlock.

press “ ” key and the reading value displayed on the LCD will keep z updating to the maximum value. Press again to select minimum value, press and hold down “ ” key 2 seconds to exit the maximum and minimum mode. z Due to the magnetic interference of the environment field factors, this magnetic field meter could display a reading value that is greater than 0.5 mG prior to measuring. This is not a malfunction of the tester. z With the tester in hand, move slowly towards to the object under measurement until it is physically touched. z Notice how the field intensity increases as you move closer to the object. z If the power of object was turned off during the measurement, the reading of tester should return to zero, unless an electromagnetic field from other sources is detected.

z This meter clock uses 24 hour time. z Press “ ” key to enter clock setting mode (1.SET). z Press “ ” or “ ” key to select option to adjust. z Press “ ” or “ ” key to change the digit. z Press “ ” key to store the setup, exit the mode.

z Press “ ” key again to auto power off time setting mode (2.SET). z Press “ ” or “ ” key to change the auto power off time. z Press “ ” key to store the setup, exit the mode. z The auto power off time default value is 5 minutes. Range is 0 to 99 minutes. To cancel auto power off, please set time to 0 minutes.

The data logging interval is the time between data records. To begin data logging, set the logging interval as per instructions below. To exit data logging, set logging interval back to 0. z Press “ ” key again to enter continuous data logging interval setting mode (3.SET). z Press “ ” or “ ” key to select option to adjust. z Press “ ” or “ ” key to change the value. z Press “ ” key to store the setup, exit the mode. Interval range is 0 seconds (no data logging) to 99 hours, 99 minutes and 99 seconds.

z Press “ ” key again to clear data logger memory for last record setting mode (4.CLA) z Press “ ” key to clear data logger memory for last record and exit the mode.

z Press “ ” key again to clear data logger memory for all record setting mode. (5.CLA) z Press “ ” key to clear data logger memory for all record. z Press “ ” key to store the setup, exit the mode.

z Press “ ” key each time to store the display reading and time stamp in memory. 11. Viewing logged reading control key z Press “ ” key to view logged readings. Press or key to scroll through the readings, Press “ ” key to exit this mode.
