capture data relevant to user application.

descriptions
Standard Power Quality, Demand, Energy optimizes the instrument to collect data
for troubleshooting using standard power quality parameters, with numerous trigger
conditions set.
Current Inrush is ideal for recording motor start-up and inrush conditions. This
setting is used when recording is triggered on change in current with longer cycle-by-
cycle waveform capture than Standard Power Quality.
Fault Recorder is similar to Inrush but with a voltage trigger.
Long-term Timed Recording, Demand, Energy sets the instrument to use periodic
measurements only. This setting is used for long-term statistical studies and
benchmarking field-based equipment testing and evaluation. No triggers are set so only
trended values are available.
Continuous Data Logging, Demand, Energy sets the instrument to log rms and
power values once per second until memory is filled or for specified time period.
EN50160 Power Quality monitors and reports Quality of Supply (QOS) compliance
as specified by the EN50160 standard. A full discussion on EN50160 is found on
Chapter 8 Reports.
NOTE
Users can override the default settings to customize the instrument to their application.
For the default settings of parameters in each monitoring mode, see Appendix B
Technical Specifications - Parameter Settings in Each Monitoring Mode on page B-10.
