SV units incorporate proprietary, analog scanners. The scanner gain and offset are adjustable, allowing the units to adapt to practically any material. ScanView software allows easy setup of scanner gain and offset. A quick method of adjusting the scanner using a special command ~Sc is described below. If the "quick method" described below is unsuccessful, follow the setup procedure in ~Hdx01nnn (page 6-10) using the ~Hd commands.

1.Set the SV unit in moving codes mode and picket fence bar code orien- tation via the ScanView Setup menus.

2.Place the SV unit at an angle as close as possible to 22 degrees from vertical (relative to the bar code) and at the correct scanning distance from the bar code to be analyzed. (See "Setting the Proper Scan Distance" on page A-1.)

3.Place an SV Calibration symbol in the laser beam at the same distance and angle that will be used in the final application.

4. Go to the Transmit a Command screen by clicking the

button.

5.Send the command ~Sc (lowercase "c")

6.Leave the screen by clicking on the RETURN button on the bottom of the Screen.

7.Press F3 to get a Reflectance profile Screen.

8.Confirm the signal levels are between the yellow lines and flat on the bottom as shown in "Figure 2 - Example of "Good" Scan Profile" on page A-4. If correct, go to step 10.

9.If the bottom of the signal is not flat, change the scan angle and repeat steps 3 -7. If the code's signal amplitude is not within the yellow lines, follow the Setup procedure by using the ~Hd commands (page 6-10). (See "Figure 3 - Examples of Scan Profile Parameters Out of Range" on page A-5)

10.At this point, the scanner gain and offset are compatible with the Calibration symbol's contrast. Place an actual symbol being used in the application in the beam at the proper distance and angle.

11.Press the "New Profile" in the Reflectance Profile screen button to get a Reflectance Profile

12.Confirm the signal levels are between the yellow lines, amplitude is 5 lines high minimum and flat on the bottom as shown in "Figure 2 - Example of "Good" Scan Profile" on page A-4. If correct, the scanner is set up for the material in the application. Go to Step 13.

13.If the bottom of the signal is not flat, or the signal level is not within the yellow lines (see "Figure 3 - Examples of Scan Profile Parameters Out of Range" on page A-5), or at least 5 lines in amplitude, the material used in the application is not adaptable to scanner settings compatible with the calibration symbol. Use steps 3-8to adjust the scanner gain
