STS400™ INSTALLATION MANUAL

1.2 TERMINOLOGY

The manual will refer to some technical terms when explaining how to choose and install the

STS400™. The following table will list the most used.

Code Resolution

Code Resolution is the width of the narrowest

module (element) in a barcode, usually

expressed in millimeters. It is also commonly

expressed in mils, (thousandths of an inch).

DOF

DOF stands for Depth Of Field and it

indicates the range (distance from the reader)

where the barcode can be read.

FOV

FOV stands for Field Of View and

describes the reading area at a given

reading distance within the DOF.

Horizontal FOV defines the reading

width of the STS400™ across the

conveyor. Vertical FOV defines the

reading length of the STS400™ parallel

to the conveyor.

The guaranteed reading volume is

defined as:

FOV

Hmin

x FOV

Vmin

x DOF

on Code 128 codes from the Datalogic

Test Chart.

Tire Terminology
