Measuring lengths with a Stanley device

Abstract

The Stanley device is of interest from the point of view of the possibility of accurately measuring lengths using direct measurement methods using tapes. We present here a description of the research methods and methods for measuring lengths with the Stanley device in the form in which they were proposed by the author of this article and applied by him when measuring the Tsagakshinskii and Kalanguyskii bases of the Balei-Darasun triangulation network. The Tsagakshinskii basis was measured by the Stanley device due to the untimely delivery of the Iederin-Guillaume wires. Kalanguyskii was measured using Iederin-Guillaume wires; the tape is applied in one area for its standardization. Standardization of the tape once again confirmed the need for long-term study of the tape, both at the same and different temperatures, in order to obtain a clear picture of changes in the tape. The result obtained during standardization should be considered as the first experience and the first approximation in the subsequent series of observations to study the tape.
