4. MEASURING PROCEDURE
4-1 AC/DC magnetic field measurement
1) Power ON the meter by pressing and holding the " Power
Button " ( 3-2, Fig. 1 )for at least 1.5 seconds .
2) magnetic field measurement Function 'DC' or 'AC' select
by pressing and holding the " FUNCTION Button " ( 3-6, Fig. 1 )
until function DC change to AC or function AC change to DC.
3) magnetic field measuremen range select
by pressing and holding the " Range Button " ( 3-5, Fig. 1 ) until
' Range 1' change to' Range 2' or 'Range 2' change to' Range 1' .
4) unit selection :
How to select the unit ( mT, G), the procedures please
refer to chapter 7-7 " Change the unit ( mT, G ) ", page 18 .

DC magnetic field measurement
* The Display will show " N " or " S " indicator.
* North pole : Display will show " N " indicator
* South pole : Display will show " S " indicator
AC magnetic field measurement
* Display will show " AC " indicator.
* Display will not show " N (S ) indicator.
5) Contact and close the testing material to the probe
head ( refer to Fig. 3 ) , the Display will show the
magnetic field value along with the unit ( mT,G ).
Fig. 3
6) Zero adjustment :
When power ON the meter, due to the environment
interference, the display may show certain values ( not
zero value), it is normal.

* Before the measurement, fix the probe at the exact
position, by pressing and holding the” ▲ ( 3-5，Fig. 1 ) “
& "▼ Button ( 3-6，Fig. 1 ) continuously at least
1.5 seconds until the display show " 0 " value, in the same
time the Display will flash once the "ZERO " indicator then
release the finger from the button.
4-2 Data Hold
During the measurement, press the " Hold Button " ( 3-3,
Fig. 1 ) once will hold the measured value & the LCD will
display a " HOLD " symbol.
* Press the " Hold Button " once again will release the data
hold function.
4-3 Data Record ( Max., Min. reading )
1) The data record function records the maximum and
minimum readings. Press the " REC Button " ( 3-4, Fig.
1 ) once to start the Data Record function and there
will be a " REC " symbol on the display.
2) With the " REC " symbol on the display :
a) Press the " REC Button " ( 3-4, Fig. 1 ) once, the "
REC MAX " symbol along with the maximum value
will appear on the display.
b) Press the " REC Button " ( 3-4, Fig. 1 ) again, the
" REC MIN " symbol along with the minimum value
will appear on the display.
c) To exit the memory record function, just press the
" REC Button " for at least 1.5 seconds. The display will
revert to the current reading.
7
Remark :
When make the DC magnetic field measurement
and execute the " RECORD " function, it can not
change from the " North pole " to " South pole "
or from the " South pole " to " North pole "
during the measurement. It can make the
measurement under the same pole ( S pole or N
pole ) only, otherwise the Max., Min. value will
be no sense.
