The process of diagnosis of milking parlors should be carried out using measuring instruments. Measuring instruments must have a maximum error which together with the statistical error of measurements guarantees that according to the requirements of ISO 5707: 2007 the data can be recorded with sufficient accuracy. Instruments must be calibrated regularly to ensure the required measurement accuracy (ISO 6690: 2007). Developed Milking machine tester v. 2.0, which consists of an automated control system with the ability to connect additional external sensors (air flow, temperature and Hall sensors), two built-in pressure sensors (based on MPX 5100DP) and batteries. The automated control system is made on the basis of the Arduino Mega 2560 hardware platform with the control keyboard and the graphic display 3.2 "320 × 480 TFT LCD. The purpose of researches is to carry out calibration of experimental sample Tester of milking installations v. 2.0 As a result of calibration of the pressure sensor included in the Tester of milking installations v. 2.0, the following was established: the calibration characteristic of the sensor is linear in the investigated pressure range (4.75-62.00 kPa); the equation describing the calibration characteristic coincides with the equation given in the technical documentation for the sensor, the error of measuring the pressure in the specified range is about 1 kPa, the calibration results do not suggest that the pressure sensor has a hysteresis effect. found that the determination of the duration of the pulse phases is characterized by a resolution of 19.70 ms and a measurement error of ± 31 ms in the frequency range of pulsations 37.3-131.0 pulses/min The magnitude of this error does not depend on the pulsation frequency in the specified range.
