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
Product Settings screen. 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
Select Product to Setup screen following a Ferrite Tune. To display the Ferrite product for selection
you will need to go to the Service Options screen.
To perform a ferrite tune, proceed as follows:
1. In the System Settings screen, tap on the Advanced icon to display the Advanced Settings
screen.
