Aircraft activation resistance measuring system and method

The invention discloses an aircraft activation resistance measuring system and method. The system comprises a digital multimeter, a plurality of measurement channels, a switch array, a short circuit calibration plug, an equivalent cable, a thermometer, and a processing module, wherein the digital multimeter communicates with one of a plurality of measurement channels or the equivalent cable through the opening and closing of the switch array, so as to measure the resistance of the to-be-measured activation resistor or the equivalent cable, which is recorded via the processing module; a guide wire is arranged in the short circuit calibration plug corresponding to the measurement channel; when the short circuit calibration plug is connected with the measurement channel, the digital multimeter communicates with the measurement channel to measure the cable resistance of the measurement channel, which is recorded by the processing module; the thermometer is used for measuring the environment temperature, which is
