Using WinPM.Net from a remote PC, initiate a waveform capture
manually by selecting the meter and issuing the acquire command.
WinPM.Net will automatically retrieve the waveform capture from the
meter. You can display the waveform for all three phases, or zoom in
on a single waveform, which includes a data block with extensive
harmonic data. See the WinPM.Net online help for instructions.
The meter can store multiple captured waveforms in its nonvolatile
memory. The number of waveforms stored is based on the number
selected. There are a maximum of five stored waveforms. All stored
waveform data is retained on power-loss.
There are two ways to store waveform captures: "FIFO" and "Fill and
Hold." FIFO mode allows the file to fill up the waveform capture file.
After the file is full, the oldest waveform capture is removed, and the
most recent waveform capture is added to the file. The Fill and Hold
mode fills the file until the configured number of waveform captures is
reached. New waveform captures cannot be added until the file is
cleared.
When the meter senses the trigger—that is, when the digital input
transitions from OFF to ON, or an alarm condition is met—the meter
transfers the cycle data from its data buffer into the memory allocated
for event captures.
Using ION Setup, you can select up to six channels to include in the
waveform capture. See the online Help for ION Setup for more
information.
