16.4 Internal Block Diagram
The voltage value is converted by attenuator and range circuits to a voltage
signal waveform proportional to the measured voltage, then isolated by an
isolating amplifier.
The sensor input is converted in a range circuit to a voltage signal waveform
proportional to the measurement current.
For details on RMS value, MEAN value, active power, waveform peak value
measurement circuit, peakover detect circuit, see Chapter 14.
