A new verification scheme for inductance measuring instruments

The basic principles of a new standard in the State Verification Scheme for inductance measuring instruments are considered, which are extended to two areas of measurement – low-frequency up to 1 MHz and high-frequency in the range 1–100 MHz. The requirements imposed on the metrological characteristics of the working standards over the whole working range of 40–10⁶ Hz are presented. Their error, instability and inductance ranges are extended (from 10 H to 10 kH). The main problems, the solution of which will facilitate the successful introduction of a new verification scheme, are indicated.
