The machine will now be looking for metal in your product, although the
sensitivity will not be fully optimised, because the detector has not yet been
calibrated for the product. Before any products can be calibrated, it will be
necessary to perform a ferrite tune in order to minimise the effects of vibration
when running products with no product effect (see section on Principles of
Operation in your User Manual for more information).
The "TUNE FOR RESISTIVE" wand used to perform a ferrite tune is located
inside the control box. Perform a ferrite tune as follows:
Change to product F (the Access ferrite entry in the User Options menu must be
set to YES). To do this press the [

To calibrate "Ferrite F" a Full calibration cycle must be completed. Before doing
this check to see if the conveyor is fitted with a photoeye prior to the detector, if
it is then return to the Configuration menu and set the Photo eye to NO (the
speed will require re-entering before you will be allowed to exit this menu). This
does not need to be done if there is no photoeye fitted. To perform a calibration,

When the "Pass product" message appears on the display, move the end of the
"Tune for Resistive Wand" with the ferrite piece back & forth through the centre
of the aperture at a rate as near as possible to the product speed until the
calibration cycle is completed. A temporary NON-METALLIC extension to the
wand will prevent hands, rings or watches entering the aperture.
