Safety:
CAUTION
Be extremely careful for the following
conditions while measuring.
Do not operate the meter in the environment with
explosive gas (material), combustible gas (material)
steam or filled with dust.
In order to avoid reading incorrect data, please replace
the battery immediately when the symbol
appears
on the LCD.
In order to avoid the damage caused by contamination or
static electricity, do not touch the circuit board before you
take any adequate action.
Operating Environment is for indoors use only. The meter
was designed for being used in an environment of
pollution degree 2.
Operation Altitude: Up to 2000M.
Operating Temperature & Humidity: 5°C ~ 40°C, 0%~
80%RH.
Storage Temperature & Humidity: -10°C ~ 60°C, 0%~
70%RH.

Operation:
1. Press to turn the power on or off.
2. Turn the meter
on, press or to select the unit of
mG(Gauss)
or μT(Tesla).
3. Position the front (see Figure 1) of the meter to measure
the electromagnetic waves. Change the measurement
angle or position to obtain the highest reading value (see
Figure 2 through Figure 6).
4. The LCD displays the measured value.
Arrow pointing direction indicates the direction of
electromagnetic waves.
NOTE: Due to the normal environmental magnetic field,
the meter may display a reading that is lower than
0.5mG prior to measuring. This is not a
malfunction of the device.
5. After the testing, turn the power off.

value displayed on the LCD will keep updating to the
maximum value.
Data Hold
Freezes the reading present on the LCD at the moment
when is pressed. Press again to disable data
hold.
