When an energy meter was tested with the help of a rotary substandard meter, the test meter made 5 turns and the rotary substandard meter disc made 2.6 turns in the same time. Rotary substandard meter and test meter constants are a 600 revolution/KWh and 1300 revolution/KWh respectively. Find the percentage error of test meter and determine if meter is running slow or fast ??
