Zeroing is highlighted in live mode and in analysis. In order to distinguish between the actual
measured value from zeroed value of reset parameter, the following rules apply:
 in live mode, the zeroed values are marked with * symbol (asterisk) next to a value (e.g.
0.000 *).
 in the data analysis, the heading of a parameter that can be zeroed is marked by adding *
symbol, e.g. "I * L1 [A]" (single cells are not selected but only the header to indicate that the
limiting function was applied).
 the display of the analyzer shows the zeroed values in grey.
3.12 Event detection
The analyzer offers wide range of event detection options for measured networks. "Event" is a
situation where the parameter value exceeds the threshold defined by the user.
Tab. 5. Types of event thresholds for each parameter.
