The invention discloses a calibration method for a pulse type lightning protection element tester and a calibration device thereof, and the method employs a high-precision calibration method based on extreme value measurement, data storage and rapid sampling, employs a piezoresistor and a DC resistor as a load together, employs a voltage breakdown simulation device to simulate the breakdown state, and achieves the simulation of the actual use state, a conventional measuring method, a reading method and a sampling method for constant waves are replaced, the defect that required parameters cannot be measured by a traditional metering method which only loads a linear resistor with a fixed resistance value is overcome, and meanwhile the measuring accuracy is guaranteed. According to the invention, the calibration problem of a pulse type lightning protection element tester is solved, especially the accurate measurement of a rapid instantaneous signal and the simulation of the actual use state of the tester are sat
