The AEMC 407 (2139.51) True-RMS Power Clamp-On Meter provides a new standard for safety and measurement capability not available in any other clamp meter sold today. Safety Rated at 1000V CAT IV, it is safe to operate in all electrical environments. It is rugged enough for the most demanding work environments and will withstand both dust and water spray with its IP54 rating. It is ergonomically designed and easily used by one hand, including function selection and button pushing even with a glove on. In addition to the standard measurement of volts, amps, frequency, resistance, diode checking and continuity, the Model 407 offers several unequaled functions including: AC, DC and AC+DC volts, amps and power, True InRush, power measurements, harmonic analysis, data logging, and more.

Unlike other instruments which only measure the InRush when the installation is first powered up, the Model 407 measures all types of InRush, even those due to load increases on an installation which is already up and running. Both peak and RMS InRush values are captured at a 1ms sample rate and 100ms duration windows.

Power measurements are available for Watts, VARs and VA, including Min and Max tracking. The Model 407 also has the unique capability to display single- and three-phase power measurements. Total Harmonic Distortion both total and referenced to the fundamental are also available taking in harmonic frequencies to the 25th order.

Harmonic analysis on individual harmonics is available up to the 25th harmonic of either 50 or 60Hz fundamental and up to the 7th harmonic on a 400Hz fundamental.

Data logging is a standard feature in the Model 407. Up to 1000 measurements can be stored from any of the function positions. Max, Min and present values are stored each time. Storage rate is programmable from 1 per second to 1 every 600 seconds. Communication to the PC is wireless via Bluetooth. Graphing and analysis of the data is accomplished by a comprehensive software package called DataView.

Other functions include Power Factor, Min/Max monitoring of measurement from any function position and Peak +/- display is available. A Hold function is provided to retain the last reading on any of the functions. The Model 407 is a truly unique meter focused on user safety, as well as measurement performance.
