The cathode-to-anode circuit of the magnetron is open-circuited and short-circuited in turn. If one of these fault conditions results in an input current that increases with decreasing voltage, the test is carried out with the appliance supplied at 0,94 times rated voltage. However, if the input current increases more than proportionally with voltage, the appliance is supplied at 1,06 times rated voltage.5 m! Q5 I0 h: M+ F
