Evaluation Techniques
EN50160 Evaluation Counters
Evaluation Counters and Evaluation Period
The PM175 uses a set of the evaluation counters for collecting
EN50160 statistics within a specified evaluation period.
The evaluation period is the period of time within which the
meter collects statistical evaluation data. Supply voltage
characteristics can be evaluated on a weekly or daily basis.
The evaluation period being normally preset in your meter to a
week can be changed via the EN50160 Advanced setup.
At the end of the evaluation period, the meter records
collected statistical evaluation data to a log file, and then
clears the evaluation registers and counters so that each
evaluation period’s statistics is stored in a separate record.
You can upload and view the online statistics data via PAS
reports, using data collected since the beginning of the
present evaluation interval. You can also manually clear the
present contents of the counters though PAS before starting
your EN50160 evaluation.
Observation Period
The observation period is the period of time within which the
voltage characteristics shall be assessed to ensure
compliance with the standard. The observation periods
