Advanced Features
In this chapter we discuss major features that, for the most part, are
found only in the Powermonitor 3000 M6 and M8 models. The
exception is that basic harmonic analysis is supported in the M4 and
M5 models.
Oscillography Oscillography captures waveforms of the voltage and current present
at the power monitor input terminals. A client application reads
oscillography records by using the indexed read method. The main
features of oscillography include the following:
•
Simultaneous capture of all seven voltage and current channels
•
Non-volatile storage of up to 8 (M6) or 2 (M8) captures
•
Configurable sampling rate up to 5.4 kHz or 90 samples per
cycle at 60 Hz
•
Captures may hold up to 408 cycles of data per channel at 60 Hz
•
Configurable data resolution of 13 bit w/ sign or 7 bit w/sign
•
Configurable pre-trigger means the capture includes waveform
information prior to the triggering event
•
Setpoints or communication may trigger oscillogram captures
•
All communication options support oscillography
You may choose to use RSPower, RSPowerPlus, or RSEnergyMetrix
software, or create a custom application, to configure oscillography
and read waveform data. RSPower software may be configured to
automatically download and save waveforms to a disk file, and then
clear the oscillography buffers.
