The DL150 single-channel and DL160 dual-channel true RMS ac voltage and current dataloggers are designed for extended recording of in-depth readings for electrical motors, components, or circuits. The compact true RMS dataloggers measure and log ac voltage to 600V and current to 200A. Sampling rates range from 1 per second to 1 per 24-hour period and recording capacity of 100,000 (DL150) or 256,000 readings (DL160). Readings can be easily downloaded via USB to a laptop or PC for analysis, trending, or exporting to Excel format using the dataloggers’ software application. The two-line LCD displays time/date, current measurement, and min/max values. The loggers can operate in both continuous (overwrite) or stop-when-full recording modes. The DL150 offers users three operating modes: normal, peak, and capture. The DL160 is useful for simultaneously logging both the current and voltage of one component or one metric from two components. A channel button alternates the display between each channel’s values. Each datalogger comes complete with current clamps, test leads, USB cable, Windows®-compatible software, universal ac adaptor, and 3.6-V lithium battery.
