Using Autofocus Barcodes

Use calibration barcodes to set the focus settings of the device automatically.
This process only adjusts the focus setting on the device and does not adjust exposure or gain.
Bring one of the following calibration barcodes into the device field of view:
5s delay
8s delay
13s delay
  1. Read one of the autofocus barcodes to start the focus tuning process based on the selected delay (8s, 13s, or 18s).
    Observe the status LED flash every 500ms during the delay, providing time to bring the test barcode into the field of view to tune the focus on it.
  2. During this delay, bring the desired test barcode into the field of view for the autofocus process to use as a reference. It is recommended to tune the focus of the device with a barcode type that is commonly decoded in your use case.
    Do not use the calibration barcode as the test barcode to calibrate focus against.
  3. After the delay, the autofocus process starts and continues for 5-15 seconds.
  4. Listen for the confirmation beeper sequence indicating the focus calibration process is complete.
Go to the ZETI section for instructions on adjusting the device's focus using the autofocus command.
