The application program opens the serial interface, so that the pulse oximeter gets voltage and starts.

For that you choose in the menu of application program: Option, Connection, the serial interface.
The application program decodes the data stream from the oximeter module and shows the data in numerical way and as Plethysmogram.
Red parts in the measurement curve show that the pulse oximeter adjusted the LED current or the preamplifier gain factor in one or more places.
The plethysmogram curve must not show jumps, but continue as a smooth line. The black marks below the graph view the progress of the internal activities of the pulse oximeter module. E.g. the regular 0.1 second long marks indicate, when the pulse LED in the test kit was turned on.
The tables show the set value and the measured value of the LED currents in the sensor.
