(747) Reads directly in gauss of a uniform magnetic field oriented parallel with the centerline of the instrument scale. WORKING CONDITION , SHOWS SOME WEAR FROM USE , ADJUSTMENT WORKS
NOTE TO MAGNETOMETER USERS
Whenever the instrume...nt pointer fails to properly return to center zero, it is indication that it has been exposed to a very high magnetic field, in excess of 400 gauss, as from permanent or electro magnets or demagnetizing equipment. Accidentally dropping the instrument onto a hard surface often cracks the pivot jewels, creating unwanted friction and sluggish action.
