Whilst the Reverse calibration cycle takes place, the metal detector will not attempt to check
for any metal contamination (the Run Detect LED will go out).
If Reject out of run has been selected in the User options menu and a photo-eye is fitted,
all packs will be rejected during the calibrate cycle.

The head power cannot be reduced any further to stop the head
overloading. Possible reasons for this could be that the calibration
pack has a large metal content, causing the head to overload; a
product not specified for operation of the machine is being used,
such that it is too conductive for the machine configuration; the
product packaging is highly conductive. If in doubt, call your nearest
Loma Service Centre.
The product has so little moisture content that it produces no product
signal, and therefore the detector has chosen to set the
compensation to minimise the effects of vibration (ie the working
mode of detection has automatically been set to DRY).
The threshold which the machine is calculating for this product is
exceeding the maximum threshold (set in the Manual Setup menu).
This would typically be because the calibrate pack is contaminated or
is too conductive for the maximum threshold setting. Check that the
correct calibrate pack(s) is representative of production packs. If in
doubt, call your nearest Loma Service Centre.
The unit is reducing the head power to account for the metal content
of the product.
The unit is using the Head Power value from Manual setup menu,
rather than determining it itself, as the head power has been locked in
that menu.
The unit is using the working mode from the Manual setup menu
rather than determining it itself, as the working mode has been locked
in that menu.
The product has little product signal, and therefore the wrong mode
of working may have been locked.
Reverse calibration was successful.
