Abstract
A measuring instrument and a method checks the functional capability of an electric heating wire of a surface heating system before it is installed and indicates damage to the heating wire while it is being installed. The instrument includes a power supply, connecting devices electrically connected to the power supply and to which the free ends of an electric heating wire can be connected such as to form a current circuit on the power supply, a resistance measuring device designed to record the electric resistance of a heating wire connected to the power supply, a display device which displays an electric resistance of a heating wire recorded by the resistance measuring device, and a warning device designed to emit an acoustic signal when the electric resistance of a heating wire recorded by the resistance measuring device strays from a target value range defined by the measuring instrument.
