The MR-4 meter adapter recorder, available from Megger, is the perfect solution for high performance power monitoring of both split-phase residential and light commercial applications. The MR-4 is capable of recording voltage and current at the meter, and it will detect sags, swells, flickers, loose neutrals and harmonic events.
The MR-4 is fast and simple to install and use. There is no need for external boxes or connections. All that's required is to pull the meter, plug in the MR-4, and then plug the meter into the MR-4 and attach the seal.
Capabilities and features of the MR-4
The MR-4 will record the currents and voltages of the two lines simultaneously, and compute line to line voltage and neutral current. This information can help determine the source of problems by identifying whether issues are on the system side or load side.
One key feature of the MR-4 is that it allows the viewing of real-time data while recording. The unit includes a built-in real-time display, as well as descriptive LEDs that can indicate problems at a glance. In addition, the MR-4 can easily record continuously for over a week, as it has 128 kilobytes of standard memory. Because the device uses flash memory, it is easy to upgrade anytime.
Additional features include a high-speed processor that enables a sample rate of 256 samples per cycle, and the ability to capture subcycle events as fast as 65 microseconds. Also, the recorder response time is adjustable from one to 60 cycles, and the data storage interval can be set from one cycle up to four hours. The MR-4 will automatically compute the TRMS value according to these settings.
