How do I view and customize Live Data (PIDs) on the Innova 5210?

While linked to the vehicle, start the engine and press the LD button to enter Live Data mode, which displays real-time sensor values such as voltage, RPM, and temperature. To customize which PIDs are shown, press and hold LD to access the Live Data Menu, select Custom Live Data, then use UP and DOWN to scroll through and select specific PIDs with the ENTER button. A maximum of two PIDs can be displayed in graph mode at any given time. (Pages 18-20)
