Operating Instructions
Min Threshold
The value entered here sets the lowest threshold that the detector can set during any Learn
process.
Max Threshold
The value entered here sets a level that during any Learn process if exceeded will abort the
process. Its purpose is to prevent a successful Learn being achieved for a contaminated sample
product.
Detection Threshold
This is the detectors working threshold, set automatically after a completed Learn process. It
may be manually set here if required.
I span Threshold
This field is only displayed if the IQ span option is enabled in the Menus > Service > Configuration >
Learn Limits menu. It is used to set the I span signal threshold (Imax – Imin) to be used during
inspection.
Q span Threshold
This field is only displayed if the IQ span option is enabled in the Menus > Service > Configuration >
Learn Limits menu. It is used to set the Q span signal threshold (Qmax – Qmin) to be used during
inspection.
Compensation
This is the product compensation set automatically from a Learn process. It cannot be manually
changed.
Phase Angle
This is the product compensation angle computed from a Learn process. It may be manually set
here if required.
Phase
Enabling this option locks the phase angle so that the detector cannot change it during a Learn
process.
Head Drive
The level of transmitter power is selected here from 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.
Head
Enabling this option locks the Head drive setting, thus preventing the detector from changing it
during a Full Learn process.
