In the process described, a test voltage is applied to an electromagnetic component, and the instantaneous test voltage at which this component responds is maintained and displayed. To do this, the variation in the current passing through said component is detected and is used for fixing and displaying the instantaneous value of the test voltage. The device according to the invention has a display system (8) which can be controlled in such a way as to display and maintain the test voltage at the electromagnetic component, as soon as the latter responds to the test voltage. |
