5.
Send the command ~Sc (lower case “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. 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 in the SV 2 Series
Operator’s Guide by using the ~Hd commands. (See Figure 3)
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.
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), 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 3-8 to adjust the scanner
gain and offset for this material and do not use any parameters that involve reflectance
measurements for failure detection for this application. See the Calibration Hints section.
14.
IMPORTANT!!
At this point the scanner is set up for the material in the application and the ~Sc
command has been used at least once to change the scanner’s setting from the initial state. To
finalize the settings,
transmit the SV command ~Hx (lower case x).
This will save the new
settings to non-volatile memory for permanent operation.
15.
The SV unit is now ready to be programmed for any application specific requirements using
output interface modes, or other modes of scanning operation such as ladder orientation, static
codes mode, etc.
