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 Individual and Aggregated XYZ Axial Data:

English
11
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 the meter.
