4.14 Performing a Ferrite Tune
A “Ferrite“ product is set up during manufacture of the detector head to provide a baseline
configuration for inspecting “Dry“ products which exhibit no product effect during inspection.
A part of this process a “Ferrite Wand“, similar to a Test Wand but much larger and containing a
sample of pure iron, is used to carry out a Full Learn process. This is called a Ferrite Tune. The
“Ferrite Wand“ used then becomes specific to the detector head and is provided with the head
to enable future Ferrite Tunes to be carried out.
To avoid it being lost, the “Ferrite Wand“ is stored inside of the detector head control panel,
fixed to the back wall of the panel. You can remove it by twisting the wand which disengages
the plastic retaining latch. The wand can then be removed from the control panel and the
panel refitted before carrying out the Ferrite Tune.
When refitting the head control panel cover, ensure that the fixing screws have
been tightened to 4Nm torque to maintain the integrity of the IP69K rating for the
head; preventing ingress of water or condensation.
When you are adding a new product to the system for inspection, you can select the “Dry“
product type option in the Menus > Set Up > Product menu. Then following a successful Full Learn
process, the “Ferrite“ settings will be used for inspecting the new product.
To avoid accidental changes being made to the Ferrite product it is always hidden from display
in the Menus > Service > Options menu following a Ferrite Tune.
To perform a ferrite tune, proceed as follows:
1. Select Menus > Service > Options to display the Service Options menu options which are listed
and described below.
2. Use the Navigation Keys to select the Access Ferrite option and press the OK /
Enter Key to select it.
3. Use the Navigation Keys to display the YES option and then press the OK / Enter
Key to select it.
