Compliance History
QOS Status
Summary
EN50160 provides a historical summary of the QOS compliance evaluations made. The
standard monitoring period is one week, usually beginning Sunday at 00:00 (midnight).
Any compliance evaluation performed in less than one week will receive an Evaluation
Status marked as Incomplete, and Compliance marked as Undetermined. For
completed monitoring periods, Compliance status may either be PASS or FAIL if all of
the specified parameters is within limits for 95% or more of the monitoring time period.
A PASS or FAIL status is hyperlinked to the compliance statistical bar chart.

History table

Voltage Compliance Report defaults to the Compliance History table as shown below.
Evaluation Status: The EN50160-specified compliance evaluation period is a 7-day
(one week) period. The evaluation status is Complete if monitoring is done within one
full week, or Incomplete if monitoring is done in less than one week. An evaluation
status is Incomplete under the following scenarios:
• It is the current evaluation period and it has simply not completed.
• It is a previous evaluation period but not enough data samples were included in the
statistical analysis. This may be due to the following reasons: data was not collected
or too many samples were tagged as unusable due to rms variations.
Evaluation Period

Each evaluation period is independent of each other. The default length of evaluation
period is a 7-day week period by which the unit calculates information in strict
compliance with the EN50160 standard.
