2.4.3 Specifics of the operation
The probe contains the permanent magnet which implies specific requirements to the device
operation:
1. If the device is moved near a knife, fork, needle, and other sharp metal objects, operator should
exercise care. Such objects may get magnetized to the probe housing and harm operator. To
avoid this, operator should hold the device should by the middle and rear part, as far from the
probe as possible.
Note – If the device is placed in proximity of a plastic magnet card, this might lead to failure of
the card.
2. If the device is placed on a loose and relatively lightweight sample, operator should hold it with
hand.
3. If operator puts the device on a test object quickly and carelessly, it might bump against due to
additional acceleration caused by the magnetic field. To save the service life of the probe, it is
recommended to place the device on a test object smoothly and hold the device meanwhile.
4. It is recommended to put the device on the test object at a 60
angle
. Once the probe touches the
test object, the device should be put upright.
Throughout the device operation, operator should check the integrity of the plastic protector of the
probe. If plastic protector is damaged and the emitting coil is opened, the probe should be replaced.
Caution!
If the device is used with the probe damaged, this may lead to device failure. When the damaged probe
(and exposed coil wires) contacts metal, this may lead to sparkling.
