Logging 9410 series
Key terms
Term Definition
COMTRADE COMmon format for TRAnsient Data Exchange (COMTRADE) is a common format
for waveform data.
ITI (CBEMA) A curve that graphically describes an AC input voltage envelope which can be
typically tolerated by information technology equipment. Meter waveform
information is plotted on this curve to help evaluate power quality.
Nominal The normal or usual parameter value. For example, the nominal voltage for many
power systems is 120 V.
Sag A power event where the voltage or current drops below the nominal value.
Swell A power event where the voltage or current rises above the nominal value.
See the ION Reference, available from www.usa.siemens.com/pds, for more
information on the Waveform Recorder module and its settings.

Configuring sag/swell logging and waveform recording using ION Setup
You can configure your meter to record sag/swell data and to capture waveforms when
it experiences a sag or swell event, and to export the waveform data to COMTRADE
files.
NOTE: For waveform recording to trigger automatically, enter your system’s
nominal (normal) voltage and current values and the amount of deviation from the
nominal that is considered a sag or a swell using the Alarming screen.
Changing your meter’s waveform recording configuration clears your meter’s existing
waveform records, including its COMTRADE files.
NOTICE
DATA LOSS
Failure to follow these instructions can result in data loss.
Ensure that all important data has been recorded before configuring waveform
recording.
1. Start ION Setup.
2. Open the Setup Assistant for your meter.
3. Navigate to Power Quality and click the Sag/Swell Logging tab.
4. Select the data log and click Edit to configure your meter’s sag/swell logging and
waveform recording parameters.
The Sag/Swell Log Setup wizard appears.
5. Set the Log Depth on the Data Logging Setup screen to specify the number of
records the sag/swell data log can hold.
