Description

Technical Field

[0001] The invention relates to the field of thermal instruments, in particular to a protective carrying device for a thermal instrument calibration instrument. Background Art

[0002] The main methods for calibrating thermal instruments are: 1. Dismantling the instrument back to the metering room and placing it on a calibration table for calibration. This is not affected by on-site environmental factors, but disassembly and assembly is time-consuming and labor-intensive. 2. On-site calibration. Because there is no vacant calibration table on site to place the calibration instrument, someone else is required to hold the calibrator and multimeter (signal generator) firmly, or place them on the ground before calibration can be performed. There is also a risk of tools accidentally falling and damaging the instrument display. In summary, existing calibration methods either require time-consuming and labor-intensive disassembly and assembly, or require two to three people to perform on-site instrument calibration and data recording. There is also a risk of damage to the instrument display, and calibration efficiency is generally low. Summary of the Invention
