Livingston, O.W. ; Vacuum Tube Engineering Department, General Electric Company, Schenectady, N.Y.

In testing large high-vacuum tubes it is difficult to take positive-grid characteristic data using ordinary voltmeters and ammeters since the heat dissipated would destroy the tube before readings could be taken. This article describes a method of applying the desired voltages for a very short time so that overheating of the tube under test is not excessive. Readings of voltage and current are taken oscillographically.
