Step 3 Position Imager And Symbol - Microscan MS-4 User Manual

Position Imager and Symbol
Step 3 — Position Imager and Symbol
• Position the Imager at a distance from the symbol that matches the factory pre-set focal
distance. For example, if your MS-4 is pre-set at 4", position the Imager's parting line 4"
from the symbol.
• Tip the Imager relative to the symbol to avoid the glare of direct (specular) reflection. The
case parting line should be perpendicular to the plane of the symbol by either pitching the
symbol or the Imager as shown.
• Position the Imager in a place with as little ambient light as possible.
• Symbols can be rotated (tilted) at any angle; however, for best results symbols should
be aligned with the FOV (field of view).
Imager Position Relative to Symbol
• In the case of linear symbols, aligning the bars in the direction of their movement ("ladder"
orientation) will minimize the chances of blurring, and will produce better reads.
• Avoid excessive skew or pitch. Maximum skew is ±30°; maximum pitch is ±30°.
Note: For instant setup and validation, the MS-4 can be hand-held or placed on its side.
For accuracy, however, Microscan's mounting arm adapter kits (P/N 98-000048-01) are
recommended.
