EXTECH INSTRUMENTS EX540 True RMS Wireless Digital Multimeter and Datalogger

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.

Clipping
Clipping is the limiting of a signal so that it never exceeds some threshold.

Line Regulation
Line regulation is the capability to maintain a constant output voltage level on the output channel of a power supply despite changes to the input voltage level.

Peak Envelope Power
Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.

RMS
RMS or root mean square is a statistical measure of the magnitude of a varying quantity
