The invention discloses grounding down lead conductivity single-person wireless measuring equipment, comprising main test equipment and a handheld terminal which are wirelessly connected through a wireless transmission module. A main test module is arranged in the main test equipment, and the handheld terminal includes a microprocessor, a handheld terminal on-off key, a micropore camera, a wireless receiving device and a handheld terminal navigation key. Real-time test data of the grounding down lead conductivity single-person wireless measuring equipment are transmitted to staff handheld terminal from the main test equipment in a wireless communication mode, the handheld terminal can photograph electrical equipment operation serial numbers and recognize and input the equipment operation serial numbers of test points in first time through OCR character recognition software in the microprocessor, automatically enable the serial numbers and the data transmitted wirelessly to be in one-to-one correspondence, and automatically generate a test record table. Completion of an experimental test for conductivity between a transformer substation grounding device grounding down lead and a main earth screen by only one worker efficiently is realized.
