PURPOSE:To use a compact shock load measuring instrument which is rich in mobility and easily used by anybody by amplifying an electric signal proportional to a shock load placed on a body by impulse hammer, and performing impedance conversion. CONSTITUTION:This measuring instrument is equipped with a signal amplifying and converting means which amplifies the electric signal proportional to the shock load placed on the body by the impulse hammer and performs impedance conversion, a peak holding means which holds the maximum value from the electric signal from this converting means, and a liquid crystal display means which converts the electric signal from the holding means from analog to digital and displays the shock load digitally. Then, the electric signal proportional to the shock load which is generated by the impulse hammer and outputted is amplified by the signal amplifying and converting means and impedance- converted. Then, the maximum value of this electric signal is held by the peak holding means and the maximum value as an analog value is A/D-converted by the liquid crystal display means and displayed as a digital value corresponding to the shock load. |
