<p>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 (for example 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.</p> |
