  "heading": "Non-registration test",
  "text": "Induction meters\n(1) Meters shall be tested to ensure that when the current circuits are open and a voltage of 110% of the marked voltage is applied to the voltage circuits, rotors cease to rotate before completing one complete revolution.\nStatic meters\n(2) Meters shall be tested for non-registration by one of the following methods–\nMethod 1\n(a) (i) When subjected to the test conditions specified in paragraph 2(1), meters shall not emit more than one output pulse over a minimum time period determined in paragraph (ii);\n(ii) Minimum test period=60000/k minutes, where k=number of pulses per kWh emitted by a meter.\nMethod 2\n(b) When static meters are fitted with inhibiting circuits, they may be tested for non-registration with a current, which is less than the threshold current in respect of a meter of that type, applied to the current circuits and a voltage of 100% of the marked voltage applied to the voltage circuits of the meters under test. Meters shall not emit more than one output pulse over a minimum time period determined as follows–\nMinimumtestperiod=126000V×I×kminutes where V=marked voltage, I=total current and k=number of pulses per kWh emitted by a meter.",
