Authors attempt to determine the accuracy of the measurements of wave-form fine structures which were recorded on photographic films during the observation period. It has been discussed first the accuracy of width measurement of pulse which usually presents itself frequently on the wave-form during thunder-storm and it has been pointed out the possibilities of over-estimation of pulse width owing to a fast sweeping speed of the bright spot on C. R. T. screen and those of underestimation of that owing to a slow sweeping speed. The weep length of the bright spot on C. R. T. screen generally fluctuates within 6% of its mean length, which is attributed to the instabilities of one shot sweeping device and supplying voltage in power line. It has been also made clear that the width of sweeping line broadens from wave-top to wave-tail and that this effect can be explained rather reasonably from the possible distortion of one shot sweeping wave form. Finally it has been made clear from our estimation that the width of a sweeping line represents almost the diameter of bright spot on C. R. T. screen when the time of weeping of bright spot is larger than 6 milli-seconds.
