Abstract

The invention relates to an output calibration device for a digital temperature instrument and a use method of the output calibration device. The output calibration device comprises a digital storageoscilloscope, a rho measurement instrument, a direct current digital ampere-voltage meter, a direct-current current voltage input terminal, a direct-current voltage input terminal, a direct-current current input terminal, a first switching value signal input terminal, a second switching value signal input terminal and the like. According to the output calibration device formed by the main parts, apointer type direct current ammeter is replaced with the intuitional and miniature direct current digital ampere-voltage meter, and an automatic potentiometer is replaced with the portable digital storage oscilloscope with storage and memory functions, so that the output calibration device is simple in structure, convenient to use and high in calibration precision. The invention simultaneously provides the use method of the calibration device. By utilizing the output calibration device and the use method, control parts of digital temperature instruments with different output control manners can be calibrated, the convenience is provided for verification and calibration workers, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to a digital temperature instrument output calibration device and a using method thereof. Background technique [0002] As we all know, digital temperature instruments can accurately and timely reflect the operating status of thermal equipment and systems, and provide reliable operating basis for operators. The quality of the digital temperature instrument will directly affect the quality of the heat treatment workpiece. Therefore, these temperature control instruments must be calibrated regularly to ensure the normal operation of these temperature measuring instruments. [0003] For the verification of digital temperature instruments, not only the verification and calibration of the temperature display part of the instrument must be carried out, but also the verification and calibration of the output control part if the instrument has a control part. At present, we know that th...
