Combines general-purpose PQ detection (with waveform recording) and four-quadrant energy monitoring in one instrument. It is housed in a DIN mounted enclosure, and is fully compliant with IEC 61000-4-30 Edition 3 Class A. It can detect and record waveforms for sags/dips, swells, interruptions, as well as recording flicker, and harmonics.

Applications
Apart from the automatic recording of power quality statistics, the high-performance data logger provides the following recording options:
Periodic data
This feature allows to record the time course of measured variables. Averaged measurements or meter contents serve as base and are saved in regular intervals. Typical applications are the acquisition of load profiles (intervals of 10s to 1h) or the determination of the energy consumption from the difference of meter readings. For both categories pre-defined courses are available, based on the system power values, and as well courses for freely selectable basic quantities. For further processing periodic data can be exported in Excel format for a definable time range.
Events
Here the occurrence of events or alarms is recorded in form of a list with time information. A distinction is made between self-defined events (such as ON/OFF of limit states or monitoring functions) which the user can classify as alarm or event and the so-called operator list in which system events such as changes of the device configuration, reset operations, powering the device and many more are held.
PQ events
The occurrence of monitored PQ events is available in list form with the most important information about the events. Each entry can be directly selected to switch to the graphical event presentation. There the courses of the RMS half-cycle values and the waveshape during the disturbance are available, divided into presentations of all voltages, all currents and mixed displays.
Event lists, PQ event recordings, mean value courses (load profiles) and meter readings may be displayed directly at the device or via the device webpage.
The instrument supports the on-site analysis of acquired measured data in order to initiate directly immediate or delayed actions. This facilitates the protection of equipment and also monitoring of service intervals.
The following items are available:
The available digital outputs may be used directly for the transmission of limit values and monitoring functions as well as the resettable summary alarm. A text may be allocated to each monitoring function and can be used for both the alarm and event list in the data logger.
The local operation at the device itself and the access via web interface are structured identically. One can access the available measured data, parametrize the instrument or use the service functions via the language-specific, topically structured menu navigation. The status bar at the top right, uniformly shows the statuses of alarm monitoring, the password protection system, the data recording and the UPS as well as time and date. Apart from the details of the PQ statistics, all data are available via both the local GUI and the WEB interface of the device.
