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):

7 External USB power supply:
External USB.
Specifications: Voltage DC 4.8 ~ 5.2V current ≧ 500mA.
A icon is displayed when an external USB power
supply is connected to the meter.
The meter determines connected USB cables to be
antennas, and thus such cables should not exceed the
top rim of the buttons during testing. If the cables
exceed this limit, the readings of subsequent tests are
considered invalid.
