64 samples over one line cycle are taken. Frequency tracking is performed

over the range of ±2Hz around the nominal line frequency (50 or 60Hz).

Harmonic measurements are calculated from these 64 samples (Harmon-

second. The measurement process is performed no more than eight times

per second. TRMS calculations are performed on a single line cycle. This

means that the input(s) are ignored between measurement intervals.

The main advantage of the logger is its ability to perform a variety of

recording tasks with easy and intuitive setup from a computer using

DataView

software.

Analog information on the input is sampled and converted to a digital

signal. This digital signal is processed and stored along with scale and

time information. An optically isolated Universal Serial Bus (USB) port

provides for the transfer of data from the instrument's internal memory

to the computer for analysis. Figure 2-1 shows a block diagram of the

logger.
