SD401 is a quality control system. The SD401 system consists of an iPhone with SD401 app and external SH7 Reader hardware (purchased separately). The SD401 app provides the GUI for displaying data. Data is received via Bluetooth communications from the SH7 Reader. Displayed data is in numeric form with the addition of alarm β€œLEDS” for each data point. The number of displayed data points is configured via a setup screen, with password control. Also, the alarm LEDS are configured with limits set for each data point. A data value within limits will be shown with a β€œgreen” LED and value outside limits with a β€œred” LED. Additional SH7 Reader readings such as temperature and battery voltage can be displayed in the app.
