The structure and use of the instrument
l. The structure of the instrument
The overall structure of the FD-MT-A ancient Egyptian magnetic balance is shown in Figure II_30. It is composed of electromagnet, steady current power supply, analytical balance magnetic balance CT5 Tesla meter, instrument switch, lighting system, water cooling system and overall frame. When the power supply of this model is stable and reliable, the cooling water must be connected.
3. Matters needing attention
(l) The main frame of the magnetic balance needs to be placed horizontally.
(2) If the current regulator of the magnetic balance fails during the experiment, turn on the main power switch, and then turn on the main power switch again, and the instrument can work normally.
(3) The Hall sensor is a vulnerable component. It is necessary to prevent the sensor from being under pressure. The current regulator should be adjusted to zero before closing the squeeze.
(4) Before use, check whether the copper tube of the Hall sensor is loose. If it is loose, it should be tightened before use.
(5) The sensor should not be used under local strong light or high temperature and corrosive gas over 60°C.
(6) Rotate during measurement: When resetting the sensor, do not use too much force to avoid damage.
After the experiment.
(7) The Hall sensor should be covered with a protective metal sleeve.
