2.2 Setting Up the Instrument
The RollerFORM comes with a USB key that contains predefined setups for
OmniScan PA series instruments. You can download one of these predefined setups to
the instrument.
When no predefined setup applies to the type of instrument you are using or your
inspection requirements, you must perform the procedures found in the sections of
this manual that contain the setup operations for the RollerFORM, as well as the setup
operations for your instrument, which are contained in its user’s manual.
To set up the RollerFORM on the OmniScan
1. Insert the USB key provided with the RollerFORM into the instrument’s USB port,
and then download the predefined setup that is best suited for your
configuration.
2. In the OmniScan MXU software, select Scan > Inspection > Type = Raster Scan.
3. Select either the unidirectional or bidirectional scanning mode.
The RollerFORM is optimized for unidirectional inspection mode. Olympus
recommends performing unidirectional inspections with this scanner. When
performing a bidirectional inspection, the guiding laser beam cannot be used to
maintain the scanner’s alignment with the guide lines traced on the surface to inspect
during scan passes in the reverse direction.
When using the RollerFORM, the following two modes are available with OmniScan
PA series instruments (equipped with the OmniScan MXU 4.1R9 software and
higher):
• Unidirectional Mode
The principal advantage of performing a unidirectional scan is that the same
starting reference is retained for each scan, because the encoder in the scan
direction is always reset to the origin value each time the clicker is pressed. This
