AEMC 407 Power Clamp Meter/Data Logger
July 30, 2025
This power clamp meter measures power parameters of single- and three-phase systems, including in rush current and frequency. Records up to 1000 measurements and is enabled with wireless Bluetooth communication.
The AEMC 407 TRMS Clamp-On Meter provides a new standard for safety and measurement capability not available in any other clamp meter sold today. They are 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 AEMC 407 offers several unequaled functions.
True InRush®
Unlike other instruments which only measure the InRush when the installation is first powered up, the AEMC 407 measures all types of InRush, even those due to load increases on and installation which is already up and running. This is an exclusive AEMC feature. 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 AEMC 407 also has the 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 on the AEMC 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 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. A truly unique meter focused on user safety as well as measurement performance.
