The AEMC ML912 Simple Logger II is a two channel AC current recording device powered by two alkaline batteries. The AEMC ML912 incorporates two user selectable measurement ranges of 0 to 100 Amps and 0 to 1000 Amps. When the AEMC ML912 performs line tracking, 64 samples are taken over one line cycle. 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 (available within DataView®). The AEMC ML912 stores TRMS values 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 AEMC ML912 Simple Logger II 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 AEMC ML912’s internal memory to the computer for analysis.
