The Simple Logger II Model L564 is a 4-channel AC voltage and current recording device powered by alkaline batteries. Voltage inputs are directly measured up to 600VAC. 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 company’s free DataView software. In addition, the product stores TRMS measurements at user-programmable rates from eight times per second to one per day. TRMS calculations are performed on a single line cycle.
