November 3, 2009 -- The Simple Logger® II Model ML912 is a two-channel AC current recording device powered by alkaline batteries. It incorporates two user selectable measurement ranges of 0.5 to 100A and 5 to 1000 A. 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 (and are only available from the Simple Logger® II Control Panel within the DataView® software).
The Simple Logger® II stores TRMS at user programmable rates of up to eight times per second. TRMS calculations are performed on a single line cycle.
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.
