P span threshold
This field is only displayed if the PQ span option is enabled in the Auto-Learn Setup screen. It
is used to set the P span signal threshold (Pmax – Pmin) to be used during inspection.
Tap in the P span threshold field to display the pop-up numeric keypad screen and enter the
value to be used.

Q span threshold
This field is only displayed if the PQ span option is enabled in the Auto-Learn Setup screen. It
is used to set the Q span signal threshold (Qmax – Qmin) to be used during inspection.
Tap in the Q span threshold field to display the pop-up numeric keypad screen and enter the

Phase angle
This is the product compensation angle computed from a Learn process.
Tap in the Phase angle field to display the pop-up numeric keypad screen and enter the value
to be used.

Phase lock
Enabling this option locks the phase angle so that the detector cannot change it during a
Learn process.
Tap in the Phase lock option check box to enable it.

Compensation
This is the product compensation set automatically from a Learn process. It cannot be
manually changed.

Head drive
The level of transmitter power is selected here from a drop down list which provides options of
MAX (maximum) full power, MED (medium) half power and LOW quarter power.
For dry products the level is normally set to MAX.
For difficult products such as metal film or products with a high or non-uniform level of
conductivity, a lower drive setting may achieve a better result.
Tap on the arrow to the right of the field to display the list of options and select the appropriate
one.

Head lock
Enabling this option locks the Head drive setting, thus preventing the detector from changing
it during a Full Learn process.
