Event log
The controller provides one event log for each sensor. The event log stores a variety of events that
occur on the devices such as calibrations done, calibration options changed, etc. A list of possible
events is shown below. The event log can be read out in a CSV format. For instructions on
downloading the logs, refer to the controller user manual.
