SMIIC MC Training on Calibration of DC Current Source

The 38st SMIIC MC Training within the SMIIC MC Work Plan 2021 – 2023 V2 was the Calibration of DC Current Source that took place on the 20 December 2022 virtually, technically hosted by SMIIC General Secretariat. 22 experts participated in the training.

The training was hosted by NMI: SASO National Metrology and Calibration Center (NMCC)

General Description: The training covers the calibration of DC current source and its uncertainty calculations.

Objective, expected outcome: To provide knowledge and to develop skills of participants in the calibration of DC current source device and calculating its uncertainty.

Who should attend: The training would be attended by staff working in metrology laboratories at the level of National Metrology Institutes or secondary level calibration laboratories
