The datalogger is a function which allows data associated with a trigger event to be recorded. The following
data are recorded:
• Analog measurements: line-to-line voltages and phase currents
• Digital events: protection events or alarms, circuit-breaker status signals, protection trips.
One or two independent recordings can be configured and, via Ekip Connect, all the associated information
can be downloaded, displayed and saved.
and emptying an internal buffer (B).
If a trigger event (A) occurs, Ekip Touch interrupts acquisition (STOP) immediately or after a time that can
be set by the user (C) and stores all the data of the window (D), which can then be downloaded to a PC for
reading and analysis.
IMPORTANT: the function requires an auxiliary voltage supply
