Learning mode
The length of the recording phase is controlled here. The ‘Trigger’ learning mode is recommended for metal
detectors with product light barriers.
User The start and end of the recording phase is controlled via the ‘New’ and ‘Finished’ buttons.
The user decides when the learning process should be ended by pressing a button.
Auto The recording phase is started by pressing the NEW button and ends automatically upon the
expiry of an adjustable time.
see chapter Adjustment  Operating level 2  Learn Product 
Adjustment  Learning duration
During learning it may be the case that the measuring signal ( 2 ) has to be adapted to the
display window ( 1 ). The recording phase then starts again from the beginning.
Trigger This learning mode is possible only with metal detectors with product light barriers.
The recording phase is started by pressing the
‘New’ button and ends automatically as soon
as the set number of products has passed the light barrier.

Learning timer (optional)
This menu option is visible only in the ‘Auto’ learning mode.
The duration of the recording phase (mm:ss:zzz) varies depending on the product and product properties.
The learning duration must be long enough for the product to be completely recorded. Standard: 5s
Product quantity (optional)
This menu option is visible only in the ‘Trigger’ learning mode.
The number of product passes varies depending on the product and the product properties. With dry products
3 product runs are often enough, while difficult products require more passes. Standard: 5
Stretching Image
So that slight product fluctuations do not lead to false triggering, the envelope is slightly enlarged at the
edges. It is assumed that the product fluctuations mainly take effect in the direction of the learning angle. For
this reason an ellipse is used to enlarge the envelope. The small radius of the ellipse corresponds to the
‘Detection level’ , while the large radius corresponds to the ‘Detection level’ multiplied by the ‘Stretching
Image’ . The orientation of the ellipse corresponds to the learning angle. Standard: 5
