The Radian Research RM-12 Metronic Portable Watthour Standard is a high accuracy portable standard. The RM-12 has the core Radian features introduced with the popular RM-10 Portable Standard while providing an increased capacity current input. The RM-12 provides one current input with a high capacity range of 0.2 to 100 Amperes.

The RM-12 is totally autoranging on the potential input, current input and auxiliary power input. Totally autoranging inputs, a feature pioneered by Radian, make it impossible to damage the unit by applying a signal to the wrong input. The RM-12 provides a true watthour display with a Kh of 1 for its entire operating range. This feature, introduced by Radian, allows for a much simpler percent registration calculation.

At only 5.5 pounds, the RM-12 is the lightest standard available making it desirable for field testing applications. Optimum field testing is achieved by using the RM-111 Automated Comparator in conjunction with the RM-12 Portable Standard. RS232-Link™ Test Software can be used to maximize automation of meter testing and results data management. A full line of additional test accessories supporting the RM-12 are also available from Radian to enhance testing of solid state or induction meters.

The RM-12 can be effectively tested and its accuracy certified by either a Radian RM-11 Primary Watthour Standard, the RS-703A Syntron Automated Calibration System, or the RS-600 Syntron Multifunction Test System.
