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
