SVScanner/Verifier Setup Procedure
Installation of an SV scanner/verifier requires proper mounting position and
output port configuration to ensure the reliable and accurate operation. This
section describes the procedures for using ScanView to ensure proper SV setup
and installation.
Each SV unit has a label showing the specified mounting distance and angle for
its particular scanner. Follow the steps below to ensure the SV unit is properly
mounted and programmed.
1. Mount the SV units at the proper distance and angle. Use
"Good Reflectance
Profile" on page 4-15
as a reference.
2. Connect the power and communication cables to SV unit.
3. Set the SV unit for picket fence bar code travel direction by clicking the
Picket Fence Mode item in the ScanView Setup Menu.
4. Place a sample bar code in the center of the intended laser beam path. For
best results, this sample should match the type of bar code(s) and material
that is to be analyzed in the final application. Knowing the X dimension
(narrow element width of the bar code(s) is a big plus as will be seen in Step
5.
5. Take a Reflectance Profile with ScanView (see
"Reflectance Profile
Screen" on page 4-12
).
a. Ensure the bar code(s) is in the center of the scan path.
b. Ensure the scan profile contains no distortion from light reflecting from
objects in or near the light path. (An example of a good reflectance pro-
file is provided in the
"Reflectance Profile Screen" on page 4-12
.). One
major aspect in a good profile is the low reflectance points (the bars) in
the symbol are uniform all the way across the code. Optimum signal
amplitude should be adjusted so the bar code element reflectances are
between the 90% and 10% marks shown in yellow on the screen. Scan-
ner angle has the most effect on the signal amplitude.
c. Continue adjusting the SV unit’s placement until a good, centered scan
profile is obtained. The scan angle may have to be altered slightly or a
light shield may have to be installed in extreme cases to achieve a good
reflectance profile.
6. *Place ScanView in Session Mode.
a. Click on the Report an Analysis Speed button.
b. Ensure that X in the bottom panel of the Bar Code Analysis Screen
matches the X dimension of the symbol /- .1 mil.
c. Adjust distance of the SV100 from the bar code until the X dimension
matches the desired value. (If X is analyzed as too large, move the scan-
ner farther away; if X is too small, move the scanner closer.)
