6.5 Digit Digital Multimeter
A proficiency test for 6.5 digit digital multimeters (DMMs) based on an HP 34401A as the travelling standard is proposed. This is a commonly used DMM in NZ and most of the top-end calibration labs can carry out such a calibration.
It is expected that the calibration should cover all ranges of the following functions:
- dc voltage and current,
- ac voltage and current,
This profiency test will be modeled on a similar exercise used in Europe. Version 2 of the EURAMET Guide is a useful reference document:
Registrations will reopen in January 2023 for this proficiency test.
Expected measurement period: May 2023 to September 2024.
The Protocol Document will be available in March 2023.
