1.Mount the SV units at the proper distance and angle. Use "Good Reflectance Profile" on page 5-6as 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.

Note: SV calibration symbols have a 10 mil X dimension unless otherwise indicted.

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 reflec- tance profile is provided in the "Reflectance Profile Screen" on page 4-12.). One major aspect in a good profile is the low reflec- tance 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. Scanner 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. If adjustment of scan angle does not produce the correct signal amplitude or placement, see Adjust- ing Scanner Gain and Offset (page 5-10) to adjust scanner gain and offset.

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 within +/- .1 mil.

c.Adjust distance of the SV100 from the bar code until the X dimen- sion matches the desired value. (If X is analyzed as too large, move the scanner farther away; if X is too small, move the scanner closer.)

7.Repeat steps 4 and 5 until no more mounting adjustments are required.

8.Remove the symbol from the laser beam path.
