8. Centre Gap
● Enables the user to separate the ringer box into two for each lead.
● The RInger comparison will be carried on the resulting sum of the values with those two boxes.
● The Centre Gap option is used when a change appears on the sides of the lead/solder areas, or when an
unwanted reflection is present in the middle of the lead width.
● Note that inserting a centre gap different from zero should lead to a revision of the current thresholds.
