Quick Check SV Series

Introduction

The Hand Held Products SV Series of Scanner/Verifiers is a universal system
component that analyzes linear bar code print quality, checks encoded data, and
detects system failures. In its basic mode of operation, an SV unit acts similar to
a normal fixed position scanner by automatically decoding bar codes as they
pass through its laser beam. Additional capabilities, such as performing bar
code verification and operating in synchronous modes make the SV Series
unique.
The SV Series combines state-of-the-art digital signal processor (DSP)
technology, a proprietary high-speed moving beam laser scanner with unique
analog output capability, and flexible I/O and communications capability. This
powerful architecture makes an SV unit an economical Quality Assurance tool
for practically any bar code print, application, or conveyance system.
The SV Series performs practically every accepted method of bar code
verification – ISO method, traditional method, encoded data format checks, and
laser scanning type analyses. These wide-ranging analysis parameters can be
used to measure bar code quality and detect failure mechanisms for any print
technology.
Bar code quality and encoded data information can be reported through the
serial communications port for each code analyzed, so accountability for all
printed bar codes is possible.
An SV Unit's I/O consists of five programmable output ports, two programmable
display LED's, and a sync input (with two interface circuit choices). This allows
the unit to be used as a local controller for pausing printers, activating lights,
gating conveyors, etc.
The SV Series is available in different models. All models operate identically, but
the scanner parameters, such as scans per second and focus distance, are
different.
