Additional functions
The metering function
Plus
offers two additional functions:
- two independent waveform buffers
- harmonic analysis
The two independent waveform buffers can be used to analyze the current and voltage values at the time of the event.
If the waveform buffers are programmed to "recording" (standard setting), continuous recording takes place until a previously defined event
occurs. Then, the recording is stopped, and the current or voltage waveforms at the time of the event can be observed on a visual display
(graphical LCD, laptop or PC). The time window is one second; the resolution is 1649 values/second.
The waveform buffers can also be started or stopped individually via the communication channels (PROFIBUS-DP, MODBUS,
c
).
The waveform buffers can be parameterized via:
- the test socket with the BDA
- the PROFIBUS-DP
- the MODBUS
- the graphical display (ETU776)
