Reasons why a simpler blood pressure user manual is imperative 1. The CMC 256 plus is a highly accurate, multifunctional six-phase relay testing and calibration device. Its high precision allows the calibration of energy meters, PQ and PMU devices. CMC 256plus - High precision relay test set and universal calibrator - OMICRON. Cmc 256plus, Technical data.

Protective relays, energy meters, measurement transducers, and power quality devices are vital components of power systems. Regular testing of all these devices is necessary to ensure their reliability. OMICRON entered this industry in 1990, and quickly rose to its leading position through continuous innovation.
Maintenance and commissioning engineers regularly have to test protection relays as well as calibrate measurement transducers, energy meters, and power quality devices. For protection relays, testing on site is common practice, whereas the other devices in many cases are sent to a laboratory for calibration, resulting in considerable efforts and costs. In order to cover all test applications and all calibration tasks on site with a single instrument, reliability, powerful output characteristics and outstanding precision must be combined in one instrument.
The CMC is controlled via a PC or laptop computer. Compatibility is a very important design principle. The software provided with the latest CMC, can also be used to control all existing CMC models. In manual operation mode, the setting of voltage and current values, phase angles, and frequencies can be done either numerically or directly in the vector diagram
The CMC stores all output values, including magnitudes, phases, and frequencies, as well as all changes to the binary inputs together with the associated timings. It also allows for the addition of user comments, and the inclusion of diagrams.

As well as manual testing, the CMC offers a variety of automated testing possibilities especially designed for individual protective functions. In particular, the CMC can be utilized to comprehensively test the protective functions of overcurrent relays, distance relays, or differential relays. In addition to these, there are many other pieces of software individually designed for testing particular protective functions, providing a system capable of testing almost all types of power system protection devices.
Through its outstanding precision, the CMC 256plus can be used for the calibration of many measurement instruments. All common types of energy meters can be tested. Furthermore, the CMC allows simulating power system conditions and thus measuring the output signals of transducers.
In modern power systems, measuring power quality has become increasingly important. Power quality measurement devices need to be periodically calibrated to ensure their continued accuracy. The CMC is capable of simulating various power quality phenomena, such as power system frequency changes, flicker, sags and swells, transients, voltage imbalance, harmonics and interharmonics.

EnerLyzer is a software option for the CMC 256-Plus and CMC 356, which enables powerful analog measurement functions. It offers 4 modes of operation: multimeter, harmonic analysis, transient recording and trend recording. It allows each of the ten measurement inputs of the CMC to be reconfigured for measuring voltages of up to 600 V or, via shunts or current clamps, it can also measure currents.

Using GPS or IRIG-B based synchronization, several CMC's can be used together to allow the user to test phasor devices. Synchronization of CMC units at either end of a power line permits the verification of communication-based distance protection schemes, or line differential protection. OMICRON has also been a driving force in providing testing solutions which utilize IEC 61850 and the UCA2 standards.
