structural principle
The instrument is supplied with pressure from an external air source (or a medical pressure ball), and the air pressure is simultaneously input into the elastic element of the tested instrument and the instrument through the input nozzle and intake valve. The elastic element is displaced at its free end under the action of air pressure, and this displacement is amplified by the connecting rod and gear transmission mechanism. The measured pressure is indicated on the dial by the pointer, and the indicated value of the tested instrument is checked.
