The Chroma 16502 MilliOhm meter has been added to the already extensive product portfolio. With a basic accuracy of 0.05%, the instrument offers a 0.001 mΩ to 1.9999 MΩ measurement range and 4½ digit resolution. Measurement time is fast at 65 ms. This makes it possible to use it as a component evaluation in a production line.
The instrument offers three ways of measuring for different material applications. The pulse-current test method is used to limit thermal EMF on the milliOhm measurement. A DC test current is used to quickly measure inductive DUTs. The dry-circuit test current is used to measure transition resistors where the maximum open-circuit voltage should not exceed 20 mV. These three ways allow the Chroma 16502 to properly measure DC resistance for various inductive components such as coils, chokes, filters and transformer windings, cables, contacts in connectors, relays, switches and conductive materials.
The Chroma 16502 offers temperature correction regardless of material or temperature. In addition, it offers a temperature conversion function for evaluation of motor and coil. To ensure the integrity of the measurement, the test tool is connected via a four-wire Kelvin connection and measurement errors are compensated by the wiring through an automatic zero function.
The built-in interfaces such as RS-232 and an optional GPIB interface allow use in both the lab and production environment.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
