The Extech EX540 is a True RMS wireless digital multimeter and datalogger offers wireless data streaming to a laptop or PC for datalogging or real-time monitoring. The EX540 transmits real-time data for monitoring, trending and analysis. In addition to wireless datalogging, the EX540 can log up to 9,999 readings internally and also reads voltage, current, resistance, capacitance, frequency (with dual-range sensitivity for electrical and electronic work), duty cycle, continuity, diode testing (2.8 volts), and even temperature (using its Type K thermistor bead probe). It features 0.06 percent accuracy that is a tough-to-beat, and a CAT IV-600-volt overvoltage safety rating, protecting users even on outdoor wiring. Several one-button data functions include minimum/maximum, relative, hold, and peak hold as well as selectable auto-ranging or manual-ranging.
