Such devices function operate continuously and restart automatically in the event of a power failure thereby providing uninterrupted data recording. Faults and system failures can be reported via email or switch outputs. An integrated scheduler within the DataService system enables additional data archiving to a PC or server. Users can then use ProfiSignal from any PC to evaluate archived data.
