1. A method for calibrating a short temperature measuring device using a dry body temperature calibrator, wherein a heat soaking block is placed in a furnace of the dry body temperature calibrator and a first temperature measuring hole and a second temperature measuring hole are provided in the heat soaking block, the method comprising the following steps:
Step S1: obtaining a temperature field model library of the heat soaking block and storing the temperature field model library in memory of the dry body temperature calibrator;
Step S2: inserting a probe of a first standard temperature sensor and a probe of the short temperature measuring device into the first temperature measuring hole and the second temperature measuring hole of the heat soaking block in the dry body temperature calibrator, respectively, keeping temperature of the first standard temperature sensor at temperature T1, and obtaining measured temperature T1′ of the short temperature measuring device;
Step S3: obtaining a temperature difference value ΔT1 for the heat soaking block at the temperature T1 according to the temperature field model library stored in the dry body temperature calibrator, wherein the temperature difference value ΔT1 is the temperature difference value between position of the probe of the first standard temperature sensor placed in the first temperature measuring hole and position of the probe of the short temperature measuring device placed in the second temperature measuring hole; and
Step S4: calculating actual temperature T1″=T1+ΔT1 at location of the probe of the short temperature measuring device, and comparing T1″ and T1′ to calibrate the short temperature measuring device at a single temperature point.
