EA30 Reading Distances
All distances are measured from the front of a non-integrated scan engine using
Grade A symbologies and an Intermec decoder. Scan rate is 30 frames/sec. An exit
window will reduce reading distances by about 4%.
Typical Reading Distances
These are typical reading distances measured in an office environment (250 lux).
