The Model 913H LED and Keyboard Test System is a low-cost, NIST traceable, highly responsive, generic switch test platform. The 913 is used to perform 100% acceptance testing, quality assurance certification, incoming inspection, and engineering development of keyboards, keypads, membranes, snap-action switches, micro switches, general-purpose switches, cables, LEDs, and seven-segment displays. The system can be use to perform a complete keyboard test, keypad test or individual switch test.

The 913H consists of a circuit card assembly (CCA) and software installed by the user in a standard personal computer. It does not require a RS-232 channel which may be needed for a barcode scanner or production line device. It features 30 channels (expandable to 90), which can be configured as an x-y matrix. Resistance ranges of both 0-5,000 and 0-50,000 ohms are featured with other ranges available upon request.

A user-friendly Windows™ software environment allows the user to create a computer screen graphic representation of the unit under test (UUT), i.e., keyboard, LED, seven-segment display, etc. The software easily "learns" the relationship of the screen graphic to the UUT. The configurations created and test data obtained can be saved for future use and SPC action.

During keyboard testing, for example, the computer graphic displays key resistance and indicates tested and active keys by changing color. An audio tone is sounded if a keys resistance is equal to or below the user-programmed specified resistance. LED voltage levels are measured and illuminated in sequential order on the UUT and display for immediate visual inspection.

The 913H switch tester is a cost-effective, password protected fast-acting tool which is accurate, operator-friendly, and extremely easy to learn and use. Production Serial Numbers can be input manually or automatically via a barcode reader.

TRICOR offers a complete line of switch tester. The Model 911A Automated Keyboard Switch Test System, consists of the 913H CCA(s), additional software, and an x-y positioning platform. This system provides automatic, accurate positioning and testing of a UUT without requiring operator intervention.
