Calculate Master Offsets
This screen-prompted routine identifies and records a Safe-Z Height for dispensing head
travel, the XYZ locations of the Purge Station, Weigh Station and Needle. It also calibrates
the camera-to-needle and probe-to-needle offsets.
This routine is performed when the dispensing system is initially installed and configured.
Those values and settings are recorded. You can run this routine again at any time to insure
dispensing accuracy or reflect hardware changes. You can choose to use the pre-recorded
values during the routine.
Definitely perform a Calculate Master Offsets if any of the following events occur:
· initial system setup (re-installation of dispensing system)
· re-initialization or re-installation of system software
· software update
· valve change (not syringe)
· camera change or location adjustment
· service station (Purge, Weigh Stations) change or location adjustment
· Needle Sensor change or location adjustment
· Height Sensor change or location adjustment
· changing from Valve Offsets
?NOTE Calculate Master Offsets and Valve Offsets both perform all of the
necessary setup functions. The main difference between the two procedures
is that Valve Offsets allows you to perform the entire process one step at a
time. Calculate Master Offsets walks through the entire process from start to
finish.
?NOTE Even though both procedures perform all of the necessary setup functions,
they are not identical. It is recommended that you use Valve Offsets as your
setup procedure.
?NOTE Calculate Master Offsets is not available on M-2000 Series dispensing
systems. It is recommended that you use Valve Offsets as your setup
procedure.
