Abstract : R. F. I. testing over the range 0.15 MHz to 3000 MHz showed the meters were not susceptable to these frequencies and were not significant radiators from an induced signal when the window was screened with .002 inch nickel mesh. Shielding attenuation was low at the low frequencies. Further temperature tests indicated the need to compensate for current change of the meters in addition to the resistance change when they are checked as voltmeters at the designated temperature levels.
