AEMC ML912 AC Simple Logger II Current Logger

The Simple Logger II ML912 is a 2-channel AC current data logger powered by 2 alkaline batteries.

The ML912 has 2 user-selectable measurement ranges of zero to 100 Amps and zero to 1000 Amps. The user can line track to receive 64 samples over one line cycle. The user can perform frequency tracking 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 DataView software). The ML912 stores TRMS values at user-programmable rates of up to 8 times per second; the TRMS calculations are performed on a single line cycle. The ML912 can perform a variety of recording tasks with easy setup from a computer using Data View software. Analog information on the input is sampled and converted to a digital signal, which is processed and stored along with time and scale information. Using the optically isolated USB port, data can be transferred from the unit’s internal memory to a computer for analysis.
