Autocalibration

This section describes how to perform Autocalibration in the WebLink user interface.

 

Autocalibration automatically determines and sets all key parameters necessary to obtain optimum decode performance on a single easy or difficult symbol.

 

This feature calculates the optimum settings necessary to achieve the highest decode success rate possible, with the lowest decoding time variance between successive read cycles.

 

Decode speed is also optimized, but is secondary to high success rate and low read time variance, since the primary factor on a production line is successful and reliable performance.

 

To begin, navigate to WebLink's Setup view. If you don't see an image, trigger the reader to capture an image.

 

 

 

Focus the reader by clicking the Focus icon and selecting the Target icon as shown below.

 

 

 

When the reader has finished focusing, click the Train button and select the Target icon as shown below.

 

 

 

This will activate the Autocalibration routine. Autocalibration progress will be shown in WebLink's Image Area.

 

 

 

When Autocalibration is complete, you will see a message stating whether it has passed or failed.

 

If it passes, the reader’s settings will be optimized to decode the symbol on which it has just been calibrated.

 

The following settings may be affected during Autocalibration to enhance decode quality:

 

You can also use the Optimize button to enhance the decode capability further.

 

 

Additional calibration options are available:
