Description
\u63cf\u8ff0
The meter is sensitive to changes of as little as 0.5 of the strength of the Earth’s magnetic field, and the tone will sound whether the field increases or decreases. Model 2 is sensitive down to 0.05 of the Earth’s magnetic field when the optional external coil is used. After the meter detects an event, when the magnetic field then becomes stable for more than about five seconds, the tone will stop and the needle will return to zero. The meter will remain at rest until the field changes again. The threshold level (squelch level) of the tone is adjustable. The user determines the amount of change in the magnetic field required to sound the tone. If the field changes by the threshold amount, the tone will come on at a low pitch. If the amount of change is larger, the tone’s pitch will be higher. This meter can also be used to determine if anything is magnetized. For example, if a bed frame is magnetized, the meter can be held vertically and slowly be swept by hand over the bed. Any changes in the direction or strength of the magnetic field will register. A similar process can reveal the presence of magnetic rocks just below the ground.
