Clamp-on AC logger

The Simple Logger II Model CL601 is a battery-powered, 1-channel recording device with an alkaline battery pack. Line tracking is performed such that 64 samples over one line cycle are taken. Harmonic measurements are calculated from these 64 samples. Frequency tracking is performed over the range of ±2 Hz around the nominal line frequency (50 or 60 Hz).

The device records true RMS AC current at user-selectable rates from 8/s to one every seven days. Currents up to 600 AAC can be measured and recorded with 0.1 A resolution. Up to 240,000 measurements can be stored.

The main advantage of the logger is its ability to perform a variety of recording tasks with intuitive set-up from a computer using DataView software. This software also provides for instrument configuration, data analysis and report generation.
