    Note: In an uncalibrated state, the verifier does not report aperture value, but uses the default aperture selection: Auto 50% for 1D applications or Auto 80% for 2D applications. Calibrate the DataMan 475 Verifier 1. Click the Calibration icon in the top left corner in the TruCheck Verification window.

  • Page 20: Guided Focus Feedback

    Guided Focus Feedback Guided Focus Feedback Guided Focus Feedback is a feature that shows you which way to turn the hand wheel of the Stand accessory to position the verifier at the proper height for optimal focus on the barcode. You can enable or disable the Guided Focus Feedback in Live Mode.
  • Page 21 Guided Focus Feedback 3. Move the verifier closer to or further from the target to make the image sharper so it can detect the code. The guidance indicator is now a green or yellow arrow. Once the code is detected, the guidance indicator shows the best direction to move the Stand handle of the Stand accessory to improve focus.
  • Page 22 Guided Focus Feedback 4. As you continue to adjust the focus, the sharpness value will reach a maximum "peak" value and then decreases as you go past the point of best focus. At this point, the guidance indicator turns green and the peak sharpness value also appears.
  • Page 23 Guided Focus Feedback Note: When you start to setup the verifier, move the verifier close to focus by trial and error. The verifier does not know if the out-of-focus image is due to the verifier being too close or too far from the image, so it cannot tell you which direction to go.
