13 - 14 Sept Training on AC/DC held at DMDM Serbia, Belgrade

„Training on AC-DC Current and Resistance“ at DMDM Serbia, Belgrade

A professional training in the field of measuring AC-DC Current and Resistance was held on 13th and 14th September 2011 at Directorate of Measures and Precious Metals (DMDM) in Belgrade with 14 participants coming from Albania, Bosnia and Herzegovina, FYR Macedonia, Montenegro and Serbia. The training was organized within the Focus Group on Facilitating National Metrology Infrastructure Development and carried out by the PTB expert Mr.Torsten Funck.

The following activities were realized:

Resistance calibration
