Using PowerLogic software from a remote PC, initiate a waveform capture manually by 
selecting the power meter and issuing the acquire command. The software will 
automatically retrieve the waveform capture from the power 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 your software’s online help or documentation for 
instructions. 

The power meter can store multiple captured waveforms in its non-volatile 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 power meter senses the trigger—that is, when the digital input transitions from 
OFF to ON, or an alarm condition is met—the power meter transfers the cycle data from its 
data buffer into the memory allocated for event captures. 

Using PowerLogic software, you can select up to six channels to include in the waveform 
capture. See your software’s online help or documentation for instructions.
