Meter Test Systems - Portable DevicesPortable meter test systems of ZERA covers reference meters, primary standards, test systems as well as current and power sources. All measurements can be performed according to IEC standard.Reference meters with accuracy classes 0.2 to 0.02 are commonly used for testing of meter installations and for observing error limits of electricity meters on-site.The primary standard with accuracy class 0.01 is used for very accurate testing of meters and reference meters. Test systems are reference meters with integrated source. You can choose between systems with current source or current and voltage source. Test systems are especially useful if you need user-defined values for current and voltage while testing meter installation with only one device.

Meter Test Systems – Stationary SystemsStationary meter test systems are suitable for economic testing of all types of meters as well as static meter of class 0.2. The wide range reference standard EPZ is used as working standard class 0.02 of the meter test system. If a higher accuracy is required the EPZ can be replaced by a comparator COM with accuracy class 0.01. All measurements can be performed according to actual standards e.g. IEC. The modular system allows an individual and customized configuration for hard- and software.A system upgrade is possible at any time.

Software for Controlling, Visualization and SimulationZERA provides a series of software for simplifying the control of test sequences, visualization and management of measured data or simulating circuit errors. Our main focus of controlling stationary Meter Test Systems is on WinSAM. Data management between portable de-vices and a PC as well as visualization of data can be realized by MTVis. If you want to control portable devices via PC your prefered choice would be SSM3000. With CheckCon 3 you can control transformer testing system. In addition to data management of CT/PT under test and evaluation of test results a big range of individual adjustable features is offered in this software package.
