Introduction

This specification is based on JJF 1071-2010 "National Metrology Calibration Code Writing Rules", JJF 1059.1-2012 "Measurement uncertainty assessment and said," JJF 1001-2011 "common measurement terms and definitions" for the preparation. This specification is first released. AC resistance box calibration specification

1 Scope

This specification applies to the frequency range of 0Hz (DC) ~ 100kHz, the resistance range of 1 × 10-3Ω ~ 1 × 107Ω The calibration of AC resistance boxes is also suitable for the AC part of AC/DC resistance boxes.

Laboratory ac resistors resistorsPart 2.Laboratorya.c.resitors For dated references, only the dated version applies to this specification; for undated references The latest version (including all amendments) applies to this specification.

3 Terms and measurement units

3.1 equivalent AC resistance equivalenta.c.resistance The real part of the AC impedance of the resistor, according to different equivalent circuit model, can be divided into series equivalent resistance or Equivalent resistance in parallel. 3.2 AC resistance time constant timeconstantofa.c.resistor Parameters that describe the residual component of the AC resistance are the ratio of the series equivalent inductance of the AC resistance to the equivalent AC resistance or Equivalent shunt capacitance and equivalent AC resistance product, in seconds. 3.3 Resistance AC/DCresistancetransfererror Resistance of the equivalent AC resistance relative to the DC resistance deviation, expressed as a percentage. 3.4 Residual inductance residualinductance Switch devices have zero block AC resistance box, when all the switching devices are placed at zero, the output of the resistance box Residual inductance Switch device without zero block AC resistance box, when all the switching devices are placed in the minimum position, and the resistance box output Resistance less than 1Ω, the resistance of the output impedance box. 3.5 Maximum operating frequency upperlimitofthenominalrangeofuseforfrequency Resistor box work, to ensure that the resistance AC-DC difference does not exceed the corresponding level index DC resistor allows the base This error and the provisions of the upper limit of frequency.
