Calibrated Offsets NOTE
Program the offset tests below to perform multiple deposits on one site only, at
the centre of the calibration board. This prevents the system from depositing
and / or measuring at every programmed site, and allows the opportunity to
make accurate measurements from a single location.

8. Select Stinger Calibrated Offset X to set the parameter initially to 0 (zero
offset). This parameter sets a factor to compensate for the offset of the
camera and the nozzle centres in the X plane.
The offset can be calculated by measuring a known point on a test product or
calibration board. Accurately draw a mark at this point and set up stinger to
dispense a corresponding dot. The measured difference between the mark and
the dot in the X plane is the value to be input. This can be any value between
-5mm and +5mm.

19. Select Dispense Sweep.
The system dispenses at the programmed site. Any offset between the pro-
grammed site and the material is the equivalent offset in the Y plane. Program
the parameter to compensate for this; it can be any value between
-5mm and +5mm.
Stinger Laser
Offsets X and Y
This parameter sets a factor to compensate for any offsets of the nozzle to laser,
in the X and Y planes, at the point where the laser actually measures. This can
be any value between -5mm and +5mm. As with the calibrated offsets, a deposit
point is marked on the calibration board. The offset is set to zero and a deposit
is made; the difference between the deposit centre and the laser centre is the
amount of compensation to be set.
Set the measurement option to measure only (on a single site).
