|Inspector Model 4000 Statement of Compliance|
The RJS Inspector 4000 performs the ISO/ANSI method of verification. This document is intended to describe the verifier’s standards of compliance.
Reflectance Compliance – 660 nm wavelength (red) light (see note 1)
The calibration plaque supplied with the Inspector 4000 is RJS part number 930-08. The plaque’s 660 nm (red) reflectance values are traceable to the Applied Image Primary Verification Calibrated Standard per ANSI X3.182 Step Reflectance Chart (see note 2).
Reflectance Compliance – 925 nm wavelength (infra-red) light (see note 1)
The 925 nm (infra-red) calibration plaque reflectance values are traceable to RJS standards developed between 1975 and 1978 for the initial Autoscan product.
ANSI Verification Method Compliance
The RJS Inspector 4000 gathers data and performs all ISO/ANSI method parameter calculations per the ISO/IEC 15416 and ANSI X3.182-1990 methodologies with special considerations and exceptions described in a following section. The Inspector 4000 also conforms to ISO/IEC 15426 per the requirements specified in Section 2.
No optical correction algorithms are incorporated in this system. One RJS proprietary calculation correction algorithm is incorporated to provide a more accurate and consistent Decodability calculation for manual scanning. This algorithm produces maximum accuracy for Decodability when a symbol is scanned in both directions during a multiple scan analysis.
The optical configuration meets all aspects of the X3.182-1990 and ISO/IEC 15416 requirements.
The four round apertures used for the ANSI verification method are each physically inspected and measured to be within +/- .0004 inch of their intended diameter sizes when in the final optical configuration.
Final system test is performed by scanning a set of test symbols that are traceable to Applied Image U.P.C. Primary Verification Standard (per ANSI X3.182) calibrated at 660 nm and 6 mil aperture (or 5 mil depending on the scanner model being tested.) All calculated parameters are confirmed to be within +/- 4 % of all target parameters marked on the symbols (see notes 1 and 2).
