2. Select a file type for your file.
3. Select the number of channels for simultaneous
recording in the file to define the file record size.
4. Select the maximum number of records you want to be
recorded in the file.
The number of records required to store a single
waveform series per event is defined as follows:
Number of Records per Series = Sampling Rate
(Samples per Cycle) x Number of Cycles per Event /
512
The total number of records you should allocate to
store the required number of events (series) is defined
as follows:
Number of Records = Number of Records per Series x
Number of Series
For example, to record 64-cycle waveforms sampled at
a rate of 32 samples per cycle, the number of records
required for one waveform series would be:
Number of Records per Series = (32 x 64)/512 = 4.
To allocate space sufficient to store 20 waveform
events (series), the waveform log file should be set up
for 4 x 20 = 80 records.
5. Click OK, and save your setup to the site database and
then send to the meter.
To configure the waveform duration, sampling rate and
channels to be recorded in the file:
1. Click on the file you wish to configure to highlight it
and then click “Setup Recorder”, or click on the
“Waveform Recorder” tab.
