III Instrument operating instruction


Step 1: Connection: connect the Hall probe with the instrument⑥;
Step 2: Power on: Press the “POWER” switch ②on the panel of handhold Gauss meter and there shall be display ①on the panel meter, it represents the instrument power has been energized and measurement can be done;
Step 3: After the power is energized, firstly select a corresponding range ③according to the magnetic field size of the measured object.
Step 4: Zero point correction: Place the Hall probe in the area whose magnetic field is zero. When the meter reading is not zero, adjust “Zero” ⑤potentiometer till the reading is zero.
Step 5: Magnetic field measurement
A. Place the Hall probe in the surface magnetic field of the measured sample, move the Hall probe and the magnetic field intensity can be directly read from the instrument, whose unit is mT and the magnetic field polarity also can be judged (When using transverse probe and the display value is “-”, the number side of the Hall probe faces N pole and when using axial probe and display value is “-”, the end side of the Hall probe faces N pole);
B. The range button, the range is 2000mT when it is pressed and the range is 200.0mT when it bounces back;
C. Contact the magnetic steel surface with Hall chip side in the practical measurement, the measurement result is closer to the actual value. When measuring with base plate side, the measurement result is little low, 1mT = 10 Gs.

IV Instrument calibration

Place the Hall probe in the standard magnetic field and adjust the “Calibration” ⑦potentiometer with small slotted screwdriver till the instrument reading is consistent with the numerical value of the standard magnetic field. Generally, it will be required to calibrate the instrument only after the Hall probe is replaced.
