There has been a need for a more efficient approach to measurement calibration. Remote calibration will significantly reduce the material and time costs of the client for transportation and calibration of the measuring tools. A method to maximize the possible automation within the framework of modern technology is proposed to reduce human participation in the calibration procedure. The problems of introducing innovative technologies are described. Such a promising way as the creation and constant expansion of the set of measuring tools is discussed which remote calibration is possible for. The software for remote calibration of the NI PXI 4072 digital multimeter in the LabVIEW graphical programming environment has been created. In order to prove the effectiveness of the remote calibration, the demonstration experiments were performed. Calibration of the multimeter in various modes on simple client-server architecture is carried out, the measurement method is given. The experimental results are also shown. Using simulation of the proposed remote calibration setup it is demonstrated that the method ensures good calibration precision. This technology is relevant for use in large network organizations geographically remote from each other.
