1. A rivet placing tool comprising:
- a head piece for admission of a rivet;
a mechanism for seizing and/or pulling a riveting bolt;
hauling equipment connected to said mechanism for seizing and/or pulling;
means for measuring values occurring with the rivet placing tool;
a mechanism for comparing said measured values with stored values; and
a mechanism for the determination of a cause of a deviation of said measured values from said stored values from a quantity of stored causes.

Abstract
A rivet setting tool is provided to provide improved monitoring of riveted connections during rivet setting. The rivet setting tool includes a head piece for holding a rivet, a device for gripping a rivet pin, a pulling apparatus connected to the device for gripping a rivet pin, and a device for measuring the tension of the pulling apparatus. Using the setting implement according to the invention, a cause of a fault can be determined by means of a comparison between measured values and stored values.
