PTB workshop "Ultrastable Low-Noise Current Amplifier"


On March 20 and 21, 2019, the workshop "Ultrastable Low-Noise Current Amplifier (ULCA) in Laboratory Practice" was held at PTB. The ULCA is a commercially available instrument, developed by PTB, that enables the measurement and generation of small currents with the highest accuracy.


Sixteen participants from national metrology institutes, the BIPM, as well as from industrial calibration laboratories and manufacturers of small current measuring instruments were made familiar in practical demonstrations and lectures with the most important application aspects of the ULCA in calibration and measuring operations. The workshop was organized and held as part of the EMPIR research project "e-SI-Amp", which aims to improve small-current metrology and the transfer of appropriate methods to users in calibration laboratories and industry.
