OMICRON Electronics CMC256PLUS


6 Phase Current + 4 Phase Voltage Test Set and Universal Calibrator

The CMC 256plus is the first choice for applications requiring very high
accuracy. This unit is not only an excellent test set for protection devices
of all kinds but also a universal calibration tool. Its high precision allows
the calibration of a wide range of measuring devices, including: electricity
meters of class 0.2, measuring transducers, power quality measurement devices
and phasor measurement units (PMU). Its unique accuracy and flexibility make
the CMC 256plus ideal for protection and measurement equipment manufacturers
for research and development, production and type testing. The CMC 256plus can
either be operated by the Test Universe software running on a PC or by the
front panel control device CMControl.
