摘要：
A method with the following steps is described for testing a Peltier element: applying a voltage to the Peltier element; switching off the voltage at the end of a defined period of time; measuring the voltage at the Peltier element; and comparing the measured voltage with a reference value.Furthermore, a small electrical appliance, such as an electric shaver, with a Peltier element is described, which small electrical appliance has a safety device which ensures that a malfunction of the Peltier element cannot result in danger to the user.
