A practical guide for modern solid-state voltage standards.
This booklet defines what a modern solid-state voltage standard should deliver for reliable laboratory work and accurate transfers between labs.
Based on a detailed review of available high-quality standards, it offers design and performance goals to help define specifications and evaluate instruments. The document describes two relevant types: a laboratory standard for maintaining a local voltage unit and a transport standard for inter-lab comparisons. It aims to set clear, achievable targets using current technology, without prescribing a single device.
- Long-term drift, stability, and how a standard maintains accuracy over time.
- Battery life, charging, and operation when unplugged or during transport.
- Electrical isolation and how outputs stay protected from other equipment and power sources.
- Environmental and physical considerations, including temperature, humidity, and shock during shipping.
Ideal for engineers, metrology staff, and labs evaluating or selecting solid-state voltage standards.
