by Ryan Egbert & Joseph Rindone The following article is part one of a four-part Metrology 101 series focusing on temperature. The written content provided here is also intended to be combined with demonstration videos […]
by Flavio Galliana, Roberto Cerri, & Davide Corona At the National Institute of Metrological Research (INRIM) an automatable precision DC voltage fixed-ratios divider allows the division ratios of DC Voltages from 10:1 to 107:1. It […]
by Walter Nowocin Selecting a Calibration Management Software System is a critical process for a calibration laboratory, especially in a bio-medical regulated environment. However, there are few examples or documents that explain this process from […]
Today, many of the units coming in for calibration don’t have a GPIB interface. All they have are a Universal Serial Bus (USB) or a TCP/IP Local Area Network (LAN) interface. When connected to the […]
PTB News 2.2021 PTB offers users from industry a new service. It can now validate whether measurement data that are transmitted within IoT networks comply with essential metrological requirements. For this purpose, PTB’s TraCIM service, […]
PTB News 2.2021 Josephson arbitrary waveform synthesizers (JAWS) allow quantized AC voltages to be synthesized with arbitrary and spectrally pure waveforms. At PTB, a pulse-driven Josephson standard for the generation of AC voltages with series […]
In a significant advance toward the future redefinition of the international unit of time, the second, a research team led by the National Institute of Standards and Technology (NIST) has compared three of the world’s […]
Summary Inconsistencies plague the mains power line, and these problems negatively impact the performance quality of electronic (as well as virtually any precision) equipment. Cleaning the power results in one less potential source of error […]
