National Institute of Standards (NIS), Egypt. The system consists mainly of a fabricated thermal current converter (TCC) associated with a definite hardware and a flexible software. The new system has been harmonized to cover a wideband range from 5 mA to 20 A at frequencies from 10 Hz to 100 kHz. In addition, the system has been used in measuring specific characteristics of the TCC, such as the time response, dc reversal errors, and the transfer errors at different frequencies. The design of the fabricated TCC was re-modified then re-calibrated in PTB, Germany to promote the system reliability.
