Setting the AuditCheck Pulse Length
The AuditCheck pulse length is the time it takes your product to travel the length of the
AuditCheck tube.
The detector automatically calculates a value for pulse length using other parameters
that have been set up—such as the model of APEX you are using, the type of application
you are running (conveyor, gravity-feed, or pipeline), and the values you have set for
other functions. However, if the internally generated pulse—for some reason—does not
give the exact result you want, you can manually enter a value.
How the Detector Calculates Pulse Length
When the value for AuditCheck pulse length is set to zero, the detector automatically
calculates the value using the following formula.
Pulse Length (ms) =
(60 * Search-Head Width) + (2 * Overhang Distance)
Product Speed
Where: Search-Head Width is in mm, Overhang Distance is in mm, and
Product Speed is in m/min.
