Design and Manufacturing Procedure;

- Determine the Customer’s exact requirements. This may need a visit to or from the Customer to discuss the options and techniques available.

- Allocate a unique “Job Number” which will be used to identify this Tester in all correspondence, forms, calibration certificates, EPROM’s etc. Most are kept for over 10 years.

- The hardware design is all on CAD software. As many existing designs as possible are used or adapted to save time and to aid reliability. Completely new designs are always “breadboarded” and fully tested before adoption.

- The software used in the internal micro is written in “C” or similar. If used, the external control PC software is now written in “Visual Basic” for easy integration with all the usual “Windows” facilities. “Qbasic” is used for the “DOS” environment.

- All the Testers are made using only components and sub-assemblies from   verifiable sources. Most are available from the large European  distributors. For any that are not,  a spare is included with the Tester.

- Construction is shared between local sub-contractors for module and printed card assembly, local specialists for machining, sheet metal-work, painting etc.  and in-house personnel.

- The final assembly is always made in-house.

- The Tester is fully checked and calibrated in-house. Its performance is recorded for future reference. All the test equipment used is regularly calibrated by external laboratories. A list of this equipment is included in the Handbook.

The Handbook of this Tester is produced which includes;

          - An introduction with photo/line drawing of the Tester,

           - The Specification of the Tester,

          - Full operating instructions for the hardware and software,

          - Calibration instructions,

          - All the relevant diagrams, electrical, mechanical, printed card layouts, parts lists etc.,

          - Repair advice and general information and

          - The Warranty and Directive Declarations.

- The Tester is delivered to the Customer, usually by Challenge Innovations staff, who install the Tester then spend at much time as needed to train the Customer’s maintenance people.
