The Model CT-7500 is a stand-alone, microcomputer-driven Breaker Analyzer. It is inexpensive and easy to use. It can operate in either of two modes: as a traditional Time-vs-Travel analyzer or as a Quick-Shot (on-line timing). In the Time-Travel mode, the CT-7500 analyzes breaker performance: contact time, stroke, velocity, over-travel, and wipe. Contact-motion analyses include: Open, Close, Open-Close, Close-Open, and Open-Close-Open. The timing window is selectable: 1- or 10-second periods. The 10-second window allows timing long duration events (e.g., circuit-switching contacts).
