Home » Cropico DO4A MilliOhm meter
The Cropico DO4A is a robust and portable digital milliOhm meter with protection up to 415 Vrms. The four-wire connection eliminates measurement errors caused by the resistance of the connecting leads. Further features are digital calibration and an accurate reading. The measuring range runs from 10 µΩ to 4 kΩ.
The instrument has a direct reading. For example, warning LEDs light up when a fault in the open circuit is detected. There is also an indication of the range and low battery voltage. The DO4A is delivered ready to use with battery, power cord and test leads, normally no extras are needed.
The internal battery of the Cropico DO4A milliOhm meter makes it possible to work for more than 14 hours without an external power supply.

"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.”
