Abstract
A jewel-bearing oscillating-ring electrodynamic ammeter is described and the method for calibrating it is explained. Data and calculations are presented to show that it is a standard of current at high frequencies. The frequency characteristics of three miniature thermocouple ammeters are measured with it.
