The utility model discloses a dynamic strain calibrating device of a foundation pile dynamic tester, which comprises a shell, the inner surface of the shell is fixedly connected with a battery, the shell is internally provided with a display screen, the right inner wall of the shell is fixedly connected with a signal amplifier, the rear inner wall of the shell is fixedly connected with a processor, and the processor is fixedly connected with a power supply. A signal line is fixedly connected to the right surface of the shell, a sensor is fixedly connected to the end, away from the shell, of the signal line, a shell is fixedly connected to the outer surface of the sensor, and a fixing ring is fixedly connected to the outer surface of the shell. By means of the structure, the balancing weight keeps the sensor to be attached to the surface of a detected object, it is avoided that due to the fact that an adhesive tape is directly attached to the lower side of the sensor, the detection precision is affected, in ad
