Design of Tensimeter Calibrators Completed with Pressure Leak Measurement Mode

Calibration is a technical activity which consists of determining and determining one or more characteristics of a product, according to a predetermined specific procedure. The purpose of calibration is to ensure the measurement results are in accordance with national and international standards. One of the medical tools that need to be calibrated is the tensimeter, while the tool for calibrating the tensimeter is the Digital Preassure Meter. The purpose of this research is to design a tensimeter calibrator equipped with a leak mode. The research design used is pure experimental research, namely the independent variable is pressure, and the dependent variable is time. The stages used are circuit design, testing and calibration. After testing, the pressure sensor can accept pressures from 0 - 250 mmHg, with an average error of 0.080 % in upward measurements and 0.063 % in downward measurements. And the average error timer from the test results obtained an error of 0.000833 %.
