摘要： The invention relates to an electric heater (4), in particular a plastic moldingplant (2) having a current path (6) comprising a first measurement tap (20), a second

measurement tap (22), a switch (16) and a third measuring tap (24 ) which are connected inseries, in which (between the first measurement tap 20) and the second measurement tap(22) is switchable, a heating element (14). The electric heater (4) also includes a diagnosticpath (28) having a first Diagnoseabgriff (30), a first voltage measuring device (52), asecond Diagnoseabgriff (32), a second voltage measuring device (54) and a thirdDiagnoseabgriff (34) which are connected in series. The first measurement tap (20) by afirst protective impedance (38) with the first Diagnoseabgriff (30), the second

measurement tap (22) by means of a second protective impedance (40) with the secondDiagnoseabgriff (32) and the third measurement tap (24) by means electrically contactedby a third protective impedance (42) to the third Diagnoseabgriff (34). The inventionfurther relates to a method (60) for operating an electric heater (4).
