Abstract

The invention relates to the technical field of heat guns, in particular to a heat gun calibrating method. According to the heat gun calibrating method, a thermal coupler which can convert temperature signals into thermoelectromotive signals, a temperature display instrument for displaying temperatures, a second chronograph for calculating time and a tramegger for measuring insulation resistance are included, wherein the temperature display instrument is connected with the thermal coupler. The heat gun calibrating method includes the following steps of inspecting the appearance, inspecting electrical safety, calibrating temperature indicating value errors, calibrating temperature stability, and expressing calibrating results. By means of the heat gun calibrating method, the problems of a measuring and calibrating method of a heat gun are solved, the heat gun can effectively conduct source tracing, confusion in measurement management of the heat gun is solved, the heat gun can normally conduct measurement calibration, management of the heat gun is standardized, the blank of an existing heat gun calibrating method is filled, the measurement calibration of the heat gun is standardized and uniformed, and measurement accuracy is improved. Meanwhile, due to the wide application of the heat gun, when measurement calibration of the heat gun is carried out, immeasurable economic benefits can be certainly brought.

Description

technical field [0001] The present invention relates to the technical field of heat guns, and more particularly, to a heat gun calibration method. Background technique [0002] Wide application of heat gun. A heat gun is a tool that uses the hot air blown out of the gun core of the heating resistance wire to solder and remove components. It is mainly composed of air pumps, airflow stabilizers, linear circuit boards, handles, housings and other basic components. Hot air guns mainly include high-speed hot air guns, constant temperature hot air guns, digital display hot air guns, etc., which are one of the important tools for maintaining communication equipment. , electronics, food and other fields. [0003] At present, there are no national or local regulations, specifications, or industry standards to refer to for the calibration of heat guns. The research on the calibration method of the heat gun is almost blank in the metrology industry, and the calibration of the heat g...
