Remote calibration system of a DC-low frequency calibtator

摘要

A system for remotely calibrating a DC-low frequency calibrator is provided to enable a central part to calibrate the remote DC-low frequency calibrator without an expert or an experienced person through the network by downloading and installing a calibration program to a client computer, and keep a national standard and retroactive property by determining an inaccurate level from a calibration result. An installer installs the calibration program by downloading an installation program from a web server(22) through the network(10). A reader reads a connection state and address by scanning a GPIB(General Purpose Interface Bus) in the client computer(50). A database server(30) includes/transmits GPIB commands according to a request of the client computer. An MTS(Multifunction Transfer Standard)(60) calibrates the calibrator(70) based on the received GPIB commands and outputs the calibration result as a response signal. An evaluator evaluates the inaccurate level of the calibrator based on the response signal. The client computer includes a display part sequentially displaying the GPIB commands and the corresponding response signal of the MTS.
