A low cost, voltage-to-frequency converter was examined. Measurements, made on a batch of 31 units, showed a linearity and long term stability of 0.3%, and a temperature coefficient of 0.05% K-1. The converters proved very satisfactory for field measurements requiring an accuracy of 1%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
