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 .

Under mT unit Under G unit

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.

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.
