9624-50 Report Wizard
On the Report Wizard – Detailed Setting page, there is a “Reference Line Low“ and "Reference Line High" setting. What is this used for?
Some customers manage their power quality based on specific guidelines either set by the customer or local authorities, so they can set these reference lows and highs and compare them to the actual measured values for reporting, etc. For example, in Japan there is a standard to measure the harmonics of PV systems before they are put into operation, and the U-THD must always be below 5%. The customer would set the reference high for U-THD at 5% so that if that measured value ever exceeds that level, an anomaly can be identified immediately.
