Main Screen with Active Results Frame.
The “Instantaneous Parameters” field contains the recent meter output parameters,
such as Active Power, Reactive Power, Apparent Power, RMS Current, RMS Voltage
and Frequency. The registers in this frame are continuously collected and refreshed on
the PC side periodically.
Table 3-1 shows examples of the meter readings.
