Table 3-2. Parameter Aggregation Matrix
Symbols: V ... applies to voltage inputs Interpolation for the RMS cycle values with 10,24kHz = 204,8 samples/cycle for 50Hz
I ... applies to current inputs Interpolation for the RMS cycle values with 10,24kHz = 176,4 samples/cycle for 60Hz
Vn ... applies to neutral line voltage (ch4, ch8)
In ... applies to neutral line current (ch8)
P ... applies only to voltage/current systems
V1 ... applies to reference channel (ch1)
Vp ... applies to phase- voltages
( ) ... calculated in PC SW (not available in the instrument)
