| Abstract: | On usual DMM only can measure signal's amplitude of DC and AC from fifty to five hundred Hz,it can not measure signal's frequency or amplitude of high frequency.By circuit design DMM can measure function signal's RMS and frequency.DMM' s measure function is stronger and the use is more convenient. |
