Abstract

The invention discloses a fully automatic calibrator, which comprises a meter, a standard source and an RS-485 bus, and the meter is connected with the standard source through the RS-485 bus. The invention also discloses a calibration method for a fully automatic calibrator, which includes the following steps: (a) enter calibration: the instrument enters the calibration state by operating the instrument, and the subsequent steps are all completed automatically; (b) sending commands: the instrument sends commands Let the standard source output a signal; (c) Wait for stability: the meter sends a judgment command to judge whether the output of the standard source is stable; (d) Calibrate: the meter starts to calibrate; (e) Repeat steps (b) to (d) until all points are calibrated; (f) Exit Calibration: Exit the instrument calibration state. The advantages of the present invention are: using the communication of the instrument and cooperating with the protocol of the standard source, the instrument is used as the master and the slave standard source is controlled, so as to achieve a fully automatic calibration process, simplify the instrument calibration process, and make the instrument calibration more flexible, which is beneficial The product reduces the input of personnel and equipment in the production process.

Description

technical field [0001] The invention relates to a fully automatic calibrator, which belongs to the technical field of electronic instruments. [0002] The invention also relates to a calibration method for a fully automatic calibrator. Background technique [0003] Nowadays, with the rapid development of the power meter industry, various power meters have emerged. How to improve the efficiency of calibrating meters is an important part of improving production efficiency. The current calibration methods are mainly manual calibration and upper computer calibration. Manual calibration requires personnel Participation is only suitable for instruments with simple calibration steps; although the calibration of the host computer is efficient, it needs to install software, and its connection is complicated and not flexible enough. Therefore, it is necessary to provide a new technical solution to solve the above technical problems. Contents of the invention [0004] The purpose o...
