6.15 Instantaneous Measurement Principles

The M650 measures all signals at an effective rate of 64 samples/cycle,
accommodating fundamental signal frequencies from 45 to 65Hz depending on model.
Samples of all bus signals are taken using a 16-Bit A/D converter, effectively creating
64 "snapshots" of the system voltage and current per cycle.

6.15.1 Sampling Rate and System Frequency

The sampling rate is synchronized to the frequency of any of the bus voltages
prioritized as follows: V1

A-N

, V1

B-N

, V1

C-N

. This is the frequency reported as the

"System Frequency". The sampling rate is the same for all channels.
