The RO4 is designed to allow for testing of Thermoelectric Generators undergoing long duration transients requiring high accuracy measurements of current and voltage.
It features a high accuracy Keysight 34972A data acquisition unit with integrated Digital Multimeter.
A USB interface connects to a computer. A PC software is provided to simultaneously control or monitor the RO4 and export data to a csv file.
TEG(s) connected to the RO4 can operate at-load and dissipate the power generated.
