Notes:
1. At 23
o
C.
2. 6.5 inches achievable with near LED (on the right when facing the front of the engine) on and far LED off.
3. Test bar codes with 2 internal LEDs flashing with 1.2A peak current, at ambient light of minimum 25 foot-candle
in the plane of the bar code.
4. Mount reflective bar codes on white or black background with minimum 4" border. Luminance in the line-of-sight
direction should be 50-120 cd/mm
2
. Ensure there is no extraneous illumination or shadow on the bar code and that
it is centered within the aiming pattern.
5. Reading criteria: 3 successful decodes out of 4 consecutive frames after setting autoexposure.
6. Provide a baffle if needed to prevent stray light from getting into the sensor fields of view.
7. Distances are measured from the front face of the scan engine chassis.
8. Near range may be closer with shorter bar codes.
9. Dependent on length of bar codes.
