4 Measurement Procedures

4.1 POWER ON/OFF Button:

Press button to power on. LCD display

measurement screen.(see Fig. 3)

Press button for 3 seconds to power off LCD

display.

4.2 Reading Data:

Direct the front section of the meter at the desired

electromagnetic field for measurements.

The meter simultaneously displays the electromagnetic

field readings of individual and aggregated XYZ axes,

where the aggregated calculation equation can be

expressed as follows:

Because of environment-related magnetic field factors,

this electromagnetic field EMF meter may display a

reading of under 0.50 mG prior to testing. This is caused

by the magnetic noise in the environment, rather than

meter failure.

4.3 Data hold (HOLD):

Press the left button as to activate the HOLD

function and hold the current readings at the upper left

of the display.

To release the held data, press the left button

again.

Press the middle button for 3 seconds to power off

TM-190

the meter.

4.4 Menu Settings:

On the measurement screen: Press the middle

button to enter the main menu, where 7 options can be

selected, namely, Brightness,Magnetic unit, RF

Strength Unit,Language,Power off,Sound, and

Information.

Press the right button to make the blue brick

scroll down. Press the right button repeatedly,

and the blue brick will cycle through the options.

Press the left button to enter the selected option.

Press the left button again to exit the selected

option and return to the main menu.

Press the middle button to return to the previous

menu.

Unitsetting comprises the following two options, namely,

Gauss/mG and Tesla/uT. Under the sub-directory, use the

option buttons to select and confirm the desired selection.

TM-190

Default: mG

4.4.4.RF Strength Unit：

Following the operation procedures in 4.4, the RF

Strength Unit setting comprises the following five

options, namely, µW/m²~mW/m², µW/cm², mV/m~V/m,

mA/m, and dBm (files are automatically skipped within

the selected unit). Under the sub-directory, use the option

buttons to select and confirm the desired selection.

Default: µV/m² ~ mW/m²
