The International Organization for Standardization (ISO) has developed a set of standards for the calibration of vibration and shock transducers. Method 3 of ISO 16063 part 11, deals specifically with the primary calibration of accelerometers over the frequency range 1 Hz to 10 kHz. Many NMIs have implemented the method over a wider frequency range. One of the difficulties faced by said NMI, is the provision of traceable low frequency AC voltage measurements. This paper considers low frequency AC voltage traceability options and investigates in more detail a measurement option defined as DC sampled AC measurements. As part of the investigation; 1) a calibration procedure is developed and implemented, 2) the measurement accuracy of the system is demonstrated.
