• In the actual detection, it should be noted that the bounce frequency of the digital rebound test hammer should not be too fast, and the time interval of the second bounce should not be less than 1 second, so as to avoid the impact on the sampling accuracy caused by the bounce of the sensor tension spring when it has not been completely reset
• Do not place the test hammer near magnets, motors or other equipment that will produce strong magnetic fields, and do not use the test hammer in an environment with strong magnetic fields. Exposure to strong magnetic field may cause abnormal operation of the test hammer or damage the test data stored in the test hammer.
• .Please do not bring the test hammer from high-temperature environment to low-temperature environment or from low-temperature environment to high-temperature environment in a short time, which may cause water vapor condensation on the internal and external surfaces of the test hammer.
