6.5 Digit Digital Multimeter

Digital Multimeter

A proficiency test for 6.5 digit digital multimeters (DMMs) based on an HP 34401A as the travelling standard is beginning in September 2023. This is a commonly used DMM in NZ and most of the top-end calibration labs can carry out such a calibration.

The calibration will cover all ranges of the following functions:

  • dc voltage and current,
  • ac voltage and current,
  • resistance.

Version 2 of the EURAMET Guide [PDF, 837 KB] is a useful reference document.

Registrations have reopened and the expected measurement period is September 2023 to September 2024.
