The "Leads / Device" tab combines the information about the device (1) (model, serial number, battery status, etc.) (2) and the lead status (stimulation, detection, impedance).
(3) The graphs below illustrates and quantifies the sensing amplitude and the lead impedance over time.
You can filter a chosen period at the top right of the graph. You can also put the mouse on a dot correlated to a date to visualize and compare the 3 data points at once.
