FIELD: measurement technology, equipment for dynamometer calibration. SUBSTANCE: device to calibrate dynamometers has base carrying loader, screw mechanism of preliminary loading, heater, power supply source, reference and calibrated dynamometers. Loader comes in the form of cylinder against which butt rocker leans. Rocker is hinged to column fixed on base. Calibrated and reference dynamometers are connected through joints. Loader is put on cylinder of loader and is connected to power supply source. EFFECT: expanded range of loads to which dynamometer is subjected, simplified loading system. 2 dwg
