Description

technical field [0001] The invention relates to a portable electric converter calibration instrument, which belongs to the field of automatic instrument calibration instruments. Background technique [0002] The electrical converter is an instrument installed on site. Due to the poor environment and the influence of the air source dirt, it is very prone to failure. Now the calibration and maintenance of the electrical converter is to remove it and take it to the instrument calibration room for calibration. It is not only inefficient but also inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a portable electrical converter calibrator that is easy to carry, convenient for on-site calibration, does not require a pressure pump, and can be quickly and accurately calibrated. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: the porta...
