1. Current Values
The Current Value, shown on the digital indicators at either the top (vertical chart view) or right hand side (horizontal chart
view) of the screen, is the latest instantaneous value and its update rate is not affected by the recording sample rate.
If the current value in the digital indicator is displayed in red, recording has been stopped for that channel – see Sections 3.4

Traces are shown only when that particular channel is being recorded. When a channel is set to Stop, its trace continues
