Types of multimeters

1. Magnetic steel never demagnetizes, and the accuracy remains consistent

The head of the new MF-47 external magnetic multimeter uses magnetically stable rare earth magnet steel. One of the advantages of this kind of magnet is that its magnetic properties are very stable. In order to adjust the accuracy of the meter head when using traditional magnetic steel, the method of magnetizing and then demagnetizing is usually used. After traditional magnetic steel is demagnetized, the magnetic steel is in a non-magnetic saturation state, and its magnetic performance stability will be significantly weakened. The accuracy of the meter will decrease when it is left or used for a long time. The new MF-47 external magnetic multimeter uses rare earth magnets with very stable magnetism. After the magnet is charged, no demagnetization is used, but patented technology is used to adjust the accuracy of the meter. This ensures that no matter how long the meter is placed or used, its accuracy is as accurate as when it left the factory. When the meter leaves the factory, the measured value indicates after being left for a long time or used for a long time

The rare earth magnet steel used in the head of the new MF-47 external magnetic multimeter has super strong magnetism. The magnetic force is 8-10 times that of traditional magnets. Due to the low magnetic force of traditional magnetic steel, the hairspring used with it is thinner and has less torque. When the instrument is vibrated, the pointer will swing a larger distance. After using rare earth magnets, you can choose a thicker hairspring to match it. As the torque of the hairspring increases, when the instrument is vibrated, the distance the pointer swings will be significantly reduced.
