Calibration
Calibration Steps
Follow this procedure for all three methods of calibration:
1. Position your symbol at the distance used in your application and confirm that it is at a
distance within the specifications for that symbol size (see Position Scanner and
Symbol on page 1-5).
2. If you are not certain of the code type, enable all code types by sending a
<P>
command
from the terminal window, or clicking on the
Autodiscrimination
button in
Calibration/
Advanced in ESP .
3. Start the calibration procedure.
Note: Once a successful calibration is completed, you may want to save the setting to
the calibration database (see Configuration Database on page 9-6).
4. Repeat calibration at other ranges and/or
symbol types you might be scanning in
your application.
5. Check your readings at each end of the
scan width required for your application,
keeping in mind that the scan width testing
may not produce results that are entirely
symmetrical.
Note: If you are setting up for laser framing,
be sure that you only test for calibration in
the active areas of the scan beam.
6. To save the new settings (including focus,
gain, and tracking) for power-on, use the
Send/Recv
button or send a
<Zp>
command.
See Configuration Database on page 9-6 to learn how to setup a database using
calibration or manually specified values.
See Advanced Calibration Features on page 9-14 for ways to speed up and
improve your calibration process.
Note: To silence the beeper, send <K702,0> or remove or block the test symbol.
