4.12.2.3 Actions taken during measurement
① Head used to pick up a component
The system automatically selects a head used to pick up a component so that a
nozzle can be replaced with another one lest frequently by attempting to use a
nozzle already attached on a head. The system may use a different head every
time it measures a component depending on the nozzle attachment conditions.
② Return of a component after measurement
Some components are returned to the original position and other ones are
discarded after measurement depending on their packaging style as shown in
Table below. When the setting item “Compo Reject to”, indicating the component
discarding method, is set to “Trash conveyor” or “Protect”, the system discards a
component according to this setting. The place onto which the system discards a
component is based on the “Compo Reject to” setting of Component data. Since
a component whose size is 1 mm or less may be placed on its side (tombstone
error) or turned upside down when it is returned, the system asks you how to
handle it.

*1 The system displays a dialog box which asks you whether to return a component or discard it.
In Continuous Measurement mode, the system displays such a dialog box before starting
continuous measurement operation.
*2 The system discards a component when the setting item “Compo Reject to” is set to “Trash
conveyor” or “Protect”.
③ Selecting a feeder which is used to pick up a component
If there are two ore more feeders assigned to the same type of component in Pick
data, a component starts being picked up based on the data you entered first as
the default setting. Only in Single Measurement mode, you can change a feeder
as desired.
④ Changing the coordinates of a pick-up position
If the system cannot pick up a component properly, manually enter the coordinates
or use the HOD device to teach the coordinates to change the coordinates of a
pick-up position.
⑤ Manual component pick-up
If there is no Pick data created, you can manually attach a component to the
nozzle. However, in this case, you cannot enter coordinates that indicate the
component pick-up position. You cannot operate a feeder either.
