1)Reading Data from Registers -> Download file
2)Maximum Memory Size -> Read below
Max Available Memory Locations in 8MB Size = 273030
Actual parameter stored in Each log (Memory locations used) = Date +time+Number of parameter selected by user
Considering your example for 2 parameters:
Number of parameter selected by user = 2 (kwh & kVA)
Actual parameter stored in Each log = 1(Date) +1(time)+ 2 (Parameters) = 4 (memory locations used per log)
Maximum log that can be stored = Max Memory Location/Actual parameter stored in Each log =273030/4= 68257
Timelog Interval setting = 15 minutes
Log in one day = (60 /Timelog Interval setting) * 24 =(60/15)*24 = 96 Logs
Max Days = Maximum log that can be stored / log in one day = 68257 / 96 = 711 days = 1 Year & 11 Months = 23 Months.

3) Frequency bandwidth and phase shift modelling schematic can be provided on request.
4) Referring to the main phase offset of 90 ° (a Rogowski coil is a derivative current transducer)
5) Considering a primary conductor of at least ? 15 mm, perpendicular and in contact with the Rogowski coil.
6) Considering an external conductor of at least ? 15 mm the same current level than internal conductor, perpendicular and in contact with the Rogowski coil.
