WARNING
The magnet is protected by a process known as “bluing”. This is the same process by which gun barrels are protected. Therefore handle the magnet only by the handles since water or skin oils can cause corrosion to occur.
Do not expose the magnet to water or high humidity!!!
At least twice a year use gun oil or WD-40 to wipe the surface of the magnet. It is important to keep oil from getting into the magnet’s coils and the probehead therefore DO NOT SPRAY OIL OR WD-40 DIRECTLY ONTO THE MAGNET, rather saturate a piece of soft cloth or patch with the oil or WD-40 and wipe the magnet’s surface thoroughly with this.
Store the magnet in the box (in which it was shipped) in a low humidity environment.
