Loggers can store 700+ years of data

摘要

Designed for users who need extended, in-depth readings, the single-channel DL150 and dual-channel DL160 true-rms ac voltage and current dat-aloggers sample at rates ranging from once a second to once a day. With maximum storage capacity of 100,000 (DL150) or 256,000 (DL160) readings, the units could maximally store over 250 or 700 years worth of data, respectively. The loggers can record signals of 10 to 600 Vac (40 Hz to 1 kHz) and 10 to 200 A (50/60 Hz).
