The OM-CP-QuadState is a four-channel, battery-powered, stand-alone state recorder. It is an all-in-one compact, portable, easy-to-use device designed to measure and record up to 52,428 state changes. The unit senses input transitions or contact closures from external sources, such as transducers and/or state initiators, and records the time and input state of the device when a transition occurs. The device can be started and stopped directly from a computer and its small size allows it to fit almost anywhere. The device operates when plugged into an available COM port. Its user-friendly software converts the PC into a real-time strip chart recorder. Data can be printed in graphical or tabular format and exported to a text or Microsoft Excel file.
