Introducción
The Extech DL150 is a True RMS AC voltage and current data logger designed for precise measurement and recording of electrical parameters. It is capable of logging up to 100,000 readings of TRMS AC Voltage (up to 600V) or Current (up to 200 Amp). This device features a user-programmable sample rate ranging from 1 second to 24 hours, providing flexibility for various monitoring needs. The integrated LCD displays real-time data including time/date, current readings, and minimum/maximum values. It also indicates if user-settable high/low alarms have been exceeded. Data can be easily downloaded to a PC via the USB interface for analysis using the included software or for export to a spreadsheet. The DL150 supports Normal, Peak, and Capture (user-specified trigger level) recording modes, making it a versatile tool for electrical diagnostics and monitoring.
