The Simple Logger® II Model L101 is a one channel recording device powered by an alkaline battery pack. Line tracking is performed such that 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. Harmonics are only available from the Simple Logger® II Control Panel within the free DataView® software included with the unit. The L101 records TRMS at a rate of up to eight times per 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 inputs are ignored between measurement intervals.
