AEMC ML912 Simple Logger II, Two-Channel TRMS MiniFlex, 1000A AC Input Range

The Simple Logger II is a two channel AC current recording device powered by two alkaline batteries. It incorporates two user selectable measurement ranges of 0 to 100 Amps and 0 to 1000 Amps. 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 (available within DataView). The Simple Logger II stores TRMS values at user programmable rates of up to eight times per second. TRMS calculations are performed on a single line cycle. 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. Accuracy (50/60Hz): 0 to 1A unspecified, 1 to 100A:+/-(1 percent of Reading + 0.5A). 0 to 5A unspecified, 5 to 1000A: +/- (1 percent of Reading + 1A). Storage rate: Programmable from 125ms to 1 day. Recording length: 15 minutes to 8 weeks, programmable using DataView. Communication: USB 2.0 optically isolated. Battery life: 100 hrs to >45 days (dependent on storage rate/recording length).
