Tip: Live Data is important function that can be used to help technicians further
diagnose a problem. This function requires technicians to be familiar with sensor
data of each system, control signals and control modes. Tip: Save known good live
data readings for comparison.

Display Modes
There are three modes with which to view Live Data, users can choose the optimum
mode according to their own needs and different parameter types.
Digital Mode: Displays parameters in numerical form.
Dashboard Mode: Displays parameters in the form of simulated instrument graphics.
Graph Mode: Displays parameters in graph form.
