AEMC's Simple Logger II Model L564 is a four-channel AC voltage and current recording device
AEMC's Simple Logger II Model L564 is a four-channel AC voltage and current recording device powered by alkaline batteries. Voltage inputs are directly measured up to 600VAC. According to the company, harmonic measurements are calculated from these 64 samples taken on each cycle measured and are available from the Simple Logger II Control Panel in the DataView software.
The Simple Logger II, Model L564, is designed to store TRMS measurements at user-programmable rates from eight times per second to one per day. TRMS calculations are engineered to be performed on a single line cycle.
According to the company, 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. Bluetooth communication is designed to provide for the transfer of data from the instrument's internal memory to the computer for analysis.
