Direct Calibration Chain for Hand Torque Screwdrivers from the National Torque Standard
ACTA IMEKO, 2015Co-Authors: K Ogushi, A Nishino, K Maeda, K UedaAbstract:Hand torque screwdrivers are used for the fastening control of screws in almost all precise mechanical and electrical parts. This paper describes the realization of a direct Calibration Chain for hand torque screwdrivers traceable to the national torque standard. The Calibration methods for a reference torque screwdriver using a primary torque standard machine, a torque screwdriver tester using the reference torque screwdriver, and hand torque screwdrivers using the torque screwdriver tester are described respectively. Uncertainty evaluation methods for each Calibration level are also explained. The effectiveness of the Calibration Chain for hand torque screwdrivers could be demonstrated.

Advantages of the Calibration Chain for hand torque screwdrivers traceable to the national torque standard
2012 Proceedings of SICE Annual Conference (SICE), 2012Co-Authors: K Ogushi, A Nishino, K Maeda, K UedaAbstract:Hand torque screwdrivers (HTDs) are ordinarily calibrated (or verified) by using torque screwdriver testers (TDTs). Weights, bars, wires and pulley devices (called Weights and Bar System: WBS) have been conventionally used for the Calibration of the TDTs as reference standards, where the mass of weights and the length of bars are separately calibrated by using each reference standard of much higher grade. However, the consistency of torque realized by the weights and bars with the torque traceable to the national torque standard has been unclear. The authors tried to establish a Calibration Chain for HTD traceable to the national standard of torque, utilizing a reference torque screwdriver (RTD), which is directly calibrated by the torque standard machine at NMIJ / AIST. The authors also compared TDT Calibration results using RTD and WBS.

A Voltage Calibration Chain for Meters Used in Measurements of EV Inductive Power Charging
'Institute of Electrical and Electronics Engineers (IEEE)', 2019Co-Authors: Zucca M., Pogliano U., Modarres M., Giordano D., Crotti G., Serazio D.Abstract:The inductive charging of electric vehicles requires specific measurement and Calibration systems. In fact, the measurement of power on board involves DC signals, which are superimposed to a significant AC ripple up to or over 150 kHz, depending on the type of charging system. A Calibration method that makes use of a phantom power, based on two independent but synchronized circuits, is considered, simulating the charging voltage and current. This paper describes in detail a solution in the realization of the voltage Calibration Chain, based on the use of a DC voltage calibrator, an injector and a voltage divider.Comment: 2 pages, Conference on Precision Electromagnetic Measurements (CPEM 2018), Paris
