Application instruction




This instrument is convenient for operator to measure magnetic

induction of DC magnetic field accurately. It is characterized by its

 wide range, clear display of LCD, and indefectible structure of sensor.

A piece of 9V dry battery, which acts as its power supply, can serve

for 4 hours continuously. Meanwhile, regulated power supply (enclosed)

 is available to 220VAC.


Measurement of surficial magnetic field of magnetic material and

special DC magnetic field; hall sensor serves either in vertical or horizontal

 according to clients' requirement.

4Parts and functions



Sensor Socket

(connect sensor and instrument)

⑥Range Select

press it to switch from 200m to 2000mT



⑦Power Switch

press it to connect

③Calibration Rheostat

adjust the current of sensor

⑧Power Socket

to connect 220VAC

Zero Rheostat

keep the sensor far away from magnetic field and adjust Zero Rheostat to display “0”

Battery Compartment

to place 9V battery


press it to switch the value from data of measurement to current of sensor



5Operational Procedure

1Close the power of the instrument, and keep the location of Range Select.

2Fit dry battery in the instrument.

3Open the power, and adjust “Zero Rheostat” to display “000”.

4Select range according to magnetic induction which is measured. Then put the instrument in measured field, and make sure the effectible side of sensor up. Keep the side, which is marked by dot hollow in the head of sensor, close to the measured magnet, and magnetic induction of this point is displayed. The value will be positive when the marked side up and this point is North Pole, otherwise South Pole.

5You’d better take dry battery out to prolong the using time of the battery after measurement. 

6Maintenance and Attentions

1Trouble may flare up in the sensor or tie-lines, if there is no reading or display “1” in measurement. If there is something wrong with tie-lines, connect them as below:



2Make sure the sensor CAN NOT endure force, bump, and extrusion.

3Keep the sensor far away from magnetic field when calibrating, or it will cause measurement error.

4Do not use it in unsuitable condition.
