 Extech Instruments says its EX540 digital multimeter is the first hand-held multimeter to offer wireless data streaming to a laptop or PC for data logging or "real-time" monitoring. The new DMM is part of the EX500 series of industrial multimeters, considered the "toughbook" of multimeters, says the company. The new Extech is a true RMS DMM that, in addition to wireless data logging, can log up to 9,999 readings internally. It also reads voltage, current, resistance, capacitance, frequency (with dual-range sensitivity for electrical and electronic work), duty cycle (dwell), continuity, diode testing (2.8V), and even temperature (using its Type K thermistor bead probe), says the company. The Extech EX540 includes double-moulded test leads, USB wireless receiver, temperature probe, magnetic hanging strap, 9-volt battery and carrying case. Additionally, NIST calibration is available.
