3-8 System Specification

600338-B

Flooring Requirements

In addition to being dust-free, physically, chemically, and

acoustically appropriate, the flooring must meet the

insulation resistance specifications. The insulation resistance

between the floor surface and earth ground must be 1 x 10

1 x 10

ohms to prevent system failure or electrical shock.

Sufficient resistance is achieved by using antistatic,

nonconducting floor tile with a resistance of 1 x 10

to 1 x 10

ohms. Provide an appropriate connection to the metal portion

of the ground plate as necessary to ensure the insulation

resistance.

Barcode Requirements

Barcode scanning of individual media labels is accurate if the

labels meets the ANSI MH10.8M-1983 standard and other

additional requirements. The requirements are:

• ANSI MH10.8M-1983 Standard

• Number of digits: 6

• Background reflection: at least 25 percent

• Print contrast: at least 75 percent

• Ratio: at least 2.2

• Module: 250 mm

• Print tolerance: ± 57 mm

• Additional Requirements

• Length of the rest zones: 5.25 mm ± 0.25 mm

• No black marks can be present in the intermediate

spaces or rest zones

• No white areas may be present on the bars

• Bars should read in a uniform direction. Nonuniform

reading directions are feasible in principle, but have a

detrimental effect on performance

• Each label should be applied in the upper right corner

of the tape cartridge recess (when oriented vertically)

• Quality Testing

Compliance with these specifications can be checked and

documented with the Ergilaser 3000 High Density bar code

measuring device that is manufactured by the Laetus

Company.
