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 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.
