Abstract
The principles of the construction and the characteristic features of the operation of an automated system proposed by the author for metrological support of machines for strength tests, which makes it possible to carry out complex monitoring of force-measurement errors, and the presetting and adjustment of test loads, are examined. The characteristic features of continuous and stepwise methods of loading with automated verification are analyzed. Use of the continuous method with slowing of the loading in the vicinity of datum points is recommended as most promising. A procedure is developed for determination of the limiting value of the loading rate with verification, disregarding the dynamic error.
