Horotec Magtest MSA 19.910 Manual page 10

Place the object to be tested on the DETECT ZONE surface.
- If the screen remains neutral (as in the image above), it means that the object placed on the detection surface is not
magnetized
- If red dots appear on the screen and a positive value in μT (as shown in the image below), it means that the object placed
on the detection surface is magnetized.
A3. In case of magnetic remanence
The following screen displays :
<->
DETECT
DEMAG
200 µT
In case of magnetic remanence, the value displayed in μT, is the difference between the value of the Earth's magnetic field
and the magnetism of the object being tested.
In addition to the value displayed in μT, red dots (up to 5) appear on the display indicating :
- By their presence, the magnetization surface
- By their size (diameter of the red dot more or less large), the importance of magnetism between the various sensors.
The value displayed in μT, will always be the highest value detected by the 5 sensors.
Place the object on the DEMAG ZONE surface and press the key
If the screen displays the presence of magnetism without any object on the detection surface DETECT ZONE, it is recommended
to reset the sensors. +
Information :
In automatic mode, the device switches directly from DETECT mode to DEMAG mode.
Once the detection is complete (screen with red dots), remove the object from the DETECT ZONE surface. The device au-
tomatically switches to DEMAG mode. Place the object on the DEMAG ZONE surface and press the DEMAG button to start
demagnetizing the object.
