Threshold
Purpose
The currently set product Threshold signal level is displayed in a number panel opposite the thick 'red'
Threshold line on the product signal dial in the
this level will be rejected. This value is set automatically during the product Learn process.
Tapping on the threshold value displays the pop-up Threshold screen through which you can adjust
the threshold value manually and therefore the sensitivity of the detector:
High numbers give lower detector performance and smaller numbers give higher detector
performance. Setting the Threshold too low will lead to false rejects.
